<p style="text-align: justify;">Aunque falte tiempo para la era de los androides o robots capaces de &#8220;pensar&#8221; por si mismos, ese momento esta un poco mas cerca debido a que investigadores de la Universidad del Sur de California han logrado crear una sinapsis artificial utilizando nanotubos de carbono. El circuito es una versión artificial de las conexiones que permiten el paso de los impulsos eléctricos entre las neuronas de nuestro cerebro, este circuito puede convertirse en el futuro componente de un cerebro artificial.</p>
<p style="text-align: justify;">El equipo de la Escuela de Ingeniería de la USC Viterbi fue dirigido por los profesores Alice Parker y Zhou Chongwu. Parker ha estado estudiando la viabilidad de crear un cerebro sintético durante los últimos cinco años, como parte del proyecto de Corteza Cerebral Biomimética en Tiempo Real (<a title="Proyecto de Corteza Cerebral Biomimetica en tiempo real" href="http://ceng.usc.edu/~parker/BioRC_research.html" target="_blank">Biomimetic Real-Time Cortex</a>).</p>
<p style="text-align: justify;"><span id="more-1496"></span>El circuito consta de  nanotubos de carbono alineados que se mantienen en una oblea de cuarzo, luego son trasladados a un substrato de silicio. El circuito  imita una sinapsis real porque es capaz de recibir y enviar impulsos u ondas en la misma forma, amplitud y duración que las neuronas en nuestro cerebro, es más pueden aun variar la intensidad de los impulsos.</p>
<p style="text-align: center;"><a title="artificialsynapse.sinapsis.artificial.circuit.cerebro.sintetico.usc.synapse.neurona.biorc por QuierounDemo, en Flickr" href="http://www.flickr.com/photos/61965272@N03/5659925647/"><img src="http://farm6.static.flickr.com/5026/5659925647_2dfbb81056_z.jpg" alt="artificialsynapse.sinapsis.artificial.circuit.cerebro.sintetico.usc.synapse.neurona.biorc" width="517" height="372" /></a></p>
<p style="text-align: justify;">Este avance es importante para el desarrollo de la inteligencia artificial (IA), pero el equipo aun no ha logrado superar el problema del alcance o magnitud, nuestros cerebros son el hogar de mas de 100 billones de neuronas, si 100 billones, y cada una de las cuales tiene aproximadamente 10,000 sinapsis. Otro problema es que los nanotubos no pueden formar nuevas conexiones , producir nuevas neuronas o adaptarse con el tiempo. Pero los cientificos estan siempre innovando y encontrando soluciones, asi que es posible que en decadas sea posible un cerebro artificial, y es más su aplicación practica en la medicina para personas que han padecido daño cerebral o terribles accidentes que han afectado su capacidad cognitiva.</p>
<p style="text-align: justify;">Comunicado de Prensa Original:</p>
<p style="text-align: justify;"><span style="color: #003366;"><strong><em>Researchers create functioning synapse using carbon nanotubes<br />
Devices might be used in brain prostheses – or combined into massive network of synthetic neurons to create a synthetic brain</em></strong><em></em></span></p>
<p><em>Engineering researchers at USC Viterbi have made a significant  breakthrough in the use of nanotechnologies for the construction of a  synthetic brain. They have built a carbon nanotube synapse circuit whose  behavior in tests reproduces the function of a neuron input, the  synapse, the a building block of the brain.</p>
<p>The team, which was led by Professor Alice Parker and Professor Chongwu  Zhou in the Ming Hsieh Department of Electrical Engineering, used an  interdisciplinary approach combining circuit design with nanotechnology  to address the complex problem of capturing brain function.</p>
<p>In a paper published in the proceedings of the Life Science Systems and  Applications Workshop in April 2011, the Viterbi team detailed how they  were able to use carbon nanotubes to create a synapse. Carbon nanotubes  are molecular carbon structures that are extremely small, with a  diameter a million times smaller than a pencil point. These nanotubes  can be used in electronic circuits, acting as metallic conductors or  semiconductors.</p>
<p>&#8220;This is a necessary first step in the process,&#8221; said Parker, who began  the complex project of looking at the possibility of developing a  synthetic brain in 2006. &#8220;We wanted to answer the question: Can you  build a circuit that would act like a neuron? The next step is even more  complex. How can we build structures out of these circuits that mimic  the neuron, and eventually the function of the brain, which has 100  billion neurons and 10,000 synapses?&#8221;</p>
<p>Parker emphasized that the fabricated synapse is simplified, the actual  development of a synthetic brain is decades away, and she said the next  hurdle for the research centers on reproducing brain plasticity in the  circuits. The human brain continually produces new neurons and adapts  throughout life, and creating this process through analog circuits will  be a monumental task, according to Parker. She believes the ongoing  research of understanding the process of human intelligence could have  long-term implications for everything from developing prosthetic  nanotechnology that would heal traumatic brain injuries to developing  intelligent, safe cars that would protect drivers in bold new ways.</p>
<p>For Jonathan Joshi, a USC Viterbi Ph.D. student who is a co-author of  the paper, the interdisciplinary approach to the problem was key to the  initial progress. Joshi said that working with Zhou and his group of  nanotechnology researchers provided the ideal dynamic of circuit  technology and nanotechnology.</p>
<p>&#8220;The interdisciplinary approach is the only approach that will lead to a  solution. We need more than one type of engineer working on this  solution,&#8221; said Joshi. &#8220;We should constantly be in search of new  technologies to solve this problem.&#8221;</p>

<p style="text-align: justify;">Una parte muy importante de la gestión del <strong>ciclo de vida de la información</strong> es la destrucción de datos al final de su vida útil. Si esto se pasa por alto, puede llevar a resultados desastrosos. Sin embargo, el método por el cual los datos en un medio en particular se destruye depende del tipo de medio. Diferentes mecanismos de destrucción de datos deben ser empleados para registros en papel, medios magnéticos, como cintas y discos duros, y medios de almacenamiento tales como unidades flash o CD / DVD que puedan contener información sensible.</p>
<p>Existen muchas formas en que puede asegurarse de que las posibilidades de que alguien pueda recuperar sus datos sean casi nulas. A continuación se presentan cinco métodos recomendados para la destrucción de datos en medios magnético.</p>
<p><span id="more-1488"></span></p>
<p style="text-align: justify;"><strong>1: Trituración</strong></p>
<p style="text-align: justify;">Hay servicios que, literalmente, destrozan la información incluyendo el disco duro. Dale una mirada al video debajo de este parrafo, en el se muestra una unidad de disco duro siendo completamente destruida. Para cualquiera que desee reconstruir los datos &#8211; <strong> sobre todo cuando los desechos de un disco duro  se mezclan con otros  residuos</strong> &#8211; sería casi imposible.</p>
<p style="text-align: center;"><object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="540" height="435" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="src" value="http://www.youtube.com/v/CTm36fcYCOc?fs=1&amp;hl=es_ES&amp;rel=0" /><param name="allowfullscreen" value="true" /><embed type="application/x-shockwave-flash" width="540" height="435" src="http://www.youtube.com/v/CTm36fcYCOc?fs=1&amp;hl=es_ES&amp;rel=0" allowscriptaccess="always" allowfullscreen="true"></embed></object></p>
<p style="text-align: justify;">En muchos casos, puede enviar los discos duros a las empresas para su destrucción. Pero  para mantener un control sobre la cadena de custodia, la empresas tambien brindan el servicio in situ, evitando que sus datos puedan caer en manos equivocadas durante el trayecto. Pero si es muy celoso con la información que posee puede comprar su propia mega-máquina tritura de datos, el unico problema es que son realmente caras.</p>
<p style="text-align: justify;"><strong>2: Desmagnetización</strong></p>
<p style="text-align: justify;">Los discos duros no son más que envases de datos, datos que se mantienen unidos a traves de una <strong>&#8220;cola magnetica</strong>&#8220;. Al  eliminar esta cola magnética, se rompe el orden en que los bits y bytes se encuentran, haciendo dificil la recuperación de información. Si  el dispositivo de desmagnetización utilizado es realmente  bueno, borrara todos los bits y bytes a nivel de usuario, así como  el formato de bajo nivel que permite el funcionamiento del disco duro. (Si realmente te preocupa la seguridad de tus  datos, utilizarás un desmagnetizador de gran alcance.)</p>
<p style="text-align: justify;">A  pesar de que la desmagnetización podría ser vista como una forma simple de borrar un disco, en realidad es un proceso destructivo &#8211;  aunque no es tan divertido de ver como una maquina trituradora, pero cumple su objetivo.</p>
<p style="text-align: center;"><object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="540" height="435" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="src" value="http://www.youtube.com/v/5zKjGQAPhUs?fs=1&amp;hl=es_ES&amp;rel=0" /><param name="allowfullscreen" value="true" /><embed type="application/x-shockwave-flash" width="540" height="435" src="http://www.youtube.com/v/5zKjGQAPhUs?fs=1&amp;hl=es_ES&amp;rel=0" allowscriptaccess="always" allowfullscreen="true"></embed></object></p>
<p style="text-align: justify;">Un  desmagnetizador realmente bueno es caro, pero no cuesta tanto como una maquina  trituradora, y podría ser suficiente para sus  necesidades. Además, es un proceso rápido. Echa un vistazo a este vídeo de YouTube de un desmagnetizador en acción.</p>
<p><strong>3: Borrado de datos con el nivel del Departamento de Defensa</strong></p>
<p style="text-align: justify;">Si cuentas con ciertos conocimientos en informática, sabrás que la eliminación de un archivo no significa que el archivo se haya &#8220;eliminado fisicamente&#8221; del disco duro, simplemente significa que el sistema operativo no lo muestra más. Por lo que recuperar archivos eliminados por el sistema puede ser una tarea bastante trivial.</p>
<p style="text-align: justify;">Entonces, ¿<strong>cómo asegurarse de que el proceso de eliminación realmente logra sus objetivos de protección de datos</strong>? Use un proceso que cumpla con las directrices del Departamento de Defensa para sobrescribir los datos. Este  proceso consiste básicamente en sobreescribir cada área del disco repetidas veces con diferentes tipos de datos (patrones).</p>
<p style="text-align: justify;">Hay todo tipo de programas destinados a eliminar de forma segura archivos e incluso todo el disco duro. Por  ejemplo, el programa SDelete de Sysinternals permite eliminar de  forma segura un solo archivo, mientras que programas tales como  East-Tec DisposeSecure extiende esta protección a los discos duros e incluyen informes críticos de validación que demuestran el  éxito del proceso. Otros ejemplos de programas similares son Active @  KillDisk,  Darik Boot y Nuke (DBAN).</p>
<p><strong>4: Fundición</strong></p>
<p style="text-align: justify;">Las personas más experimentadas pueden encontrar una forma de frustrar  sus esfuerzos de destrucción de datos, incluso si destruye físicamente  el disco duro o borra su campo magnético.</p>
<p><strong>El  problema</strong>: Incluso después de la destrucción, aunque ya no tenga campo  magnético o este hecho pedazos, el disco duro se encuentra  todavía en el mismo estado físico.<br />
<strong>La solución</strong>: Realizar un proceso que cambie el disco duro de sólido a líquido. Esto es extremo, pero puede ser necesario para algunos tipos de datos.</p>
<p><a title="fundir disco duro metal aluminio " href="http://eecue.com/c/driveslag/index.php?artid=1" target="_blank">Estos muchachos han tomado medidas extremas</a> para asegurarse que nadie puede recuperar sus datos.</p>
<p style="text-align: justify;">Cambiando el tono a uno más serio, existe una  temperatura en la que los medios magnéticos pierden su magnetismo y no son capaces de mantener los datos. Llamado punto de Curie, después de que esta temperatura es alcanzada, los bits y bytes ya no están perfectamente ordenados. He elaborado el siguiente cuadro  para mostrar los puntos de Curie de cada metal generalmente utilizado en soportes magnéticos:</p>
<p style="text-align: center;"><a title="punto.curie.point.metales.metals.celsius.centigrados.temperatura.temperature.fundicion por QuierounDemo, en Flickr" href="http://www.flickr.com/photos/61965272@N03/5654858046/"><img src="http://farm6.static.flickr.com/5029/5654858046_8dabc93508.jpg" alt="punto.curie.point.metales.metals.celsius.centigrados.temperatura.temperature.fundicion" width="363" height="127" /></a></p>
<p>Ya sea que incineres o fundas el disco duro, una vez alcanzadas  estas temperaturas o cambiado su estado de solido a  líquido, es casi imposible recuperar sus datos.</p>
<p style="text-align: justify;"><strong>5: Cifrado Total</strong><br />
Si  bien este método no es destructivo, cifrar los datos es una práctica rutinaria puede  ayudar a protegernos contra las miradas indiscretas a la hora de deshacernos de los soportes magneticos o cualquier otro tipo de dispositivo de almacenamiento. La desventaja de este método es que no es 100% infalible y puede ser violado por alguien con el profundo deseo de obtener dicha información. La ventaja es que el atacante necesita acceso físico al sistema operativo del equipo.</p>

<p align="justify">Pues despues de mucho tiempo logré ejecutar el famoso Ma Os X Leopardo. Mis primeros intentos fueron instalarlo directamente en el computador pero despues de muchos intentos infructuosos y cansado de crear y borrar particiones me decidi por una solución emulada.</p>
<p align="justify"><span id="more-500"></span></p>
<p align="justify">Asi que me dedique a buscar una imagen de Os X Leopard, que pudiera correr sobre VMWare y asi probar este sistema operativo. El sentimiento de satisfacción al ver ejecutandose el &#8220;lindo gatito&#8221; es intenso, en mi caso corre como un gato sano, porque aunque esta emulado no es lento. Hay que aclarar que mi computadora tiene las siguientes especificaciones:</p>
<ul>
<li>Core 2 Duo 2.6 Ghz</li>
<li>4 GB DD3</li>
<li>1 GB DDR3 Video</li>
<li>500 GB disco Duro</li>
<li>Blue Ray Rom Drive</li>
<li>Windows Vista Home Premium 64 Bits</li>
<li> Bluetooth 2.0</li>
</ul>
<p>Esta es mi primera vez con el sistema operativo de apple inc. y la verdad que es muy distinto y a la vez excitante, el manejo de las ventanas, el uso de un menu omnipresente y que cambia de acuerdo a la aplicacion activa, el diseño estilisado, etc. La verdad que yo me enamore del Ipod touch, y desde entonces estoy con la fervorosa intención de desarrollar aplicaciones para esta plataforma.</p>
<p>En la proximas entregas espero poder hacer una guia de como programar con el iphone SDK, pero lo primero es lograr instalarlo. Ya veremos.</p>
<p>Aqui algunas imagenes adicionales y un video.</p>

			<content:encoded><![CDATA[<p>Before you spend a dime on security, there are many precautions you can take that will protect you against the most common threats.</p>
<p>1. Check Windows Update and Office Update regularly.</p>
<p>2. Install a personal firewall.</p>
<p>3. Install a free spyware blocker.</p>
<p>4. Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger service (this is unrelated to the instant messaging program). Open Control Panel | Administrative Tools | Services and you&#8217;ll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. Bye-bye, spam pop-ups! Any good firewall will also stop them.</p>
<p>5. Use strong passwords and change them periodically. Passwords should have at least seven characters; use letters and numbers and have at least one symbol. A decent example would be f8izKro@l. This will make it much harder for anyone to gain access to your accounts.</p>
<p>6. If you&#8217;re using Outlook or Outlook Express, use the current version or one with the Outlook Security Update installed. The update and current versions patch numerous vulnerabilities.</p>
<p>7. Buy antivirus software and keep it up to date.</p>
<p>8. If you have a wireless network, turn on the security features: Use MAC filtering, turn off SSID broadcast, and even use WEP with the biggest key you can get. For more, check out our wireless section or see the expanded coverage in Your Unwired World in our next issue.</p>
<p>9. Join a respectable e-mail security list, then you learn about emerging threats quickly and can take proper precautions.</p>
<p>10. Be skeptical of things on the Internet. Don&#8217;t assume that e-mail &#8220;From:&#8221; a particular person is actually from that person until you have further reason to believe it&#8217;s that person. Don&#8217;t assume that an attachment is what it says it is. Don&#8217;t give out your password to anyone, even if that person claims to be from &#8220;support.&#8221;</p>

			<content:encoded><![CDATA[<p>Some people seem to think our network is a kind of a store a they just pick what they want without sharing anything!<br />
(and other considere our net as a schoolyard where one &#8220;trade&#8221;&#8230; Childish!)</p>
<p>You can help everybody getting rid of them by boycotting them that way:<br />
You &#8220;browse&#8221; each uploading user.</p>
<p>** If he/she shares more than, say, a hundred files (and NOT in the WinMx directory only, putting them elsewhere and unshared when entirely downloaded !!!), OK.<br />
NB: a hundred is not a lot but 1- we don&#8217;t all have a large HDD and some files are big 2- when you begin&#8230;!<br />
** If not:</p>
<p>You can send a message to him/her to ask why there is no real share, or not at all, for they can have forgotten to do so: give them a chance! The first time, I didn&#8217;t understand that I had to choose the shared files types, so I shared nothing, unwillingly. Somebody told it to me in a message.</p>
<p>If no answer and/or still no shared file, you can exclude the selfish beast:<br />
(Thanks to dwhite who gave the modus operandi on the WinMx net)</p>
<p>To block somebody from downloading, add the name to your HOTLIST (right-click the name then &#8220;Add to hotlist&#8221;) then to your IGNORE list.</p>
<p>You won&#8217;t receive any messages nor will they enter your queue, during that session at least.</p>
<p>On the contrary, you can help people who share a lot by starting the tranfer when they are in your queue, or give a higher bandwith priority&#8230;</p>

			<content:encoded><![CDATA[<p>Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.<br />
<u><strong>Network Connectivity</strong></u><br />
The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.</p>
<p>If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).</p>
<p><u><strong>Traffic</strong></u><br />
A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.</p>
<p>Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters &#8211; A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).</p>
<p>If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person&#8217;s file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).</p>
<p><u><strong>Hosting Bandwidth</strong></u><br />
In the example above, we discussed traffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc.) . The page itself is simply a file that creates traffic just like the MP3 file in the example above (however, a web page is usually much smaller than a music file).</p>
<p>A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 Kilobytes = 200,000 bytes = 1,600,000 bits). This is typically large for a web page. In comparison, Yahoo&#8217;s home page is about 70KB.</p>
<p><u><strong>How Much Bandwidth Is Enough?</strong></u><br />
It depends (don&#8217;t you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis<br />
If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:<br />
Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor</p>
<p>If you intend to allow people to download files from your site, your bandwidth calculation should be:<br />
<strong>[(Average Daily Visitors x Average Page Views x Average Page Size) +<br />
(Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor</strong><br />
Let us examine each item in the formula:</p>
<ul>
<li>Average Daily Visitors &#8211; The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.</li>
<li>Average Page Views &#8211; On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.</li>
<li>Average Page Size &#8211; The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.</li>
<li>Average Daily File Downloads &#8211; The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.</li>
<li>Average File Size &#8211; Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.</li>
<li>Fudge Factor &#8211; A number greater than 1. Using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.</li>
</ul>
<p>Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.</p>
<p><u><strong>Summary</strong></u></p>
<p>Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth allocated in your plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.</p>

			<content:encoded><![CDATA[<p align="justify">First of all, this tweak only apply to those who only have one HDD on their primary IDE channel (nothing else on device 0 or 1) and a CD-ROM and/or DVD-ROM on the secondary IDE channel. Each time you boot Windows XP, there&#8217;s an updated file called NTOSBOOT-*.pf who appears in your prefetch directory (%SystemRoot%Prefetch) and there&#8217;s no need to erease any other files as the new prefetch option in XP really improves loading time of installed programs. We only want WindowsXP to boot faster and not decrease its performance. Thanks to Rod Cahoon (for the prefetch automation process&#8230;with a minor change of mine) and Zeb for the IDE Channel tweak as those two tricks, coupled together with a little modification, result in an EXTREMELY fast bootup:</p>
<p>1. Open notepad.exe, type &#8220;del c:windowsprefetch tosboot-*.* /q&#8221; (without the quotes) &amp; save as &#8220;ntosboot.bat&#8221; in c:<br />
2. From the Start menu, select &#8220;Run&#8230;&#8221; &amp; type &#8220;gpedit.msc&#8221;.<br />
3. Double click &#8220;Windows Settings&#8221; under &#8220;Computer Configuration&#8221; and double click again on &#8220;Shutdown&#8221; in the right window.<br />
4. In the new window, click &#8220;add&#8221;, &#8220;Browse&#8221;, locate your &#8220;ntosboot.bat&#8221; file &amp; click &#8220;Open&#8221;.<br />
5. Click &#8220;OK&#8221;, &#8220;Apply&#8221; &amp; &#8220;OK&#8221; once again to exit.<br />
6. From the Start menu, select &#8220;Run&#8230;&#8221; &amp; type &#8220;devmgmt.msc&#8221;.<br />
7. Double click on &#8220;IDE ATA/ATAPI controllers&#8221;<br />
8. Right click on &#8220;Primary IDE Channel&#8221; and select &#8220;Properties&#8221;.<br />
9. Select the &#8220;Advanced Settings&#8221; tab then on the device 0 or 1 that doesn&#8217;t have &#8216;device type&#8217; greyed out select &#8216;none&#8217; instead of &#8216;autodetect&#8217; &amp; click &#8220;OK&#8221;.<br />
10. Right click on &#8220;Secondary IDE channel&#8221;, select &#8220;Properties&#8221; and repeat step 9.<br />
11. Reboot your computer.</p>
<p>WindowsXP should now boot REALLY faster.</p>

We only want WindowsXP to boot faster and not decrease its performance. Thanks to Rod Cahoon (for the prefetch automation process&#8230;with a minor change of mine) and Zeb for the IDE Channel tweak as those two tricks, coupled together with a little modification, result in an EXTREMELY fast bootup:</p>
<p>1. Open notepad.exe, type &#8220;del c:windowsprefetch tosboot-*.* /q&#8221; (without the quotes) &amp; save as &#8220;ntosboot.bat&#8221; in c:<br />
2. From the Start menu, select &#8220;Run&#8230;&#8221; &amp; type &#8220;gpedit.msc&#8221;.<br />
3. Double click &#8220;Windows Settings&#8221; under &#8220;Computer Configuration&#8221; and double click again on &#8220;Shutdown&#8221; in the right window.<br />
4. In the new window, click &#8220;add&#8221;, &#8220;Browse&#8221;, locate your &#8220;ntosboot.bat&#8221; file &amp; click &#8220;Open&#8221;.<br />
5. Click &#8220;OK&#8221;, &#8220;Apply&#8221; &amp; &#8220;OK&#8221; once again to exit.<br />
6. From the Start menu, select &#8220;Run&#8230;&#8221; &amp; type &#8220;devmgmt.msc&#8221;.<br />
7. Double click on &#8220;IDE ATA/ATAPI controllers&#8221;<br />
8. Right click on &#8220;Primary IDE Channel&#8221; and select &#8220;Properties&#8221;.<br />
9. Select the &#8220;Advanced Settings&#8221; tab then on the device 0 or 1 that doesn&#8217;t have &#8216;device type&#8217; greyed out select &#8216;none&#8217; instead of &#8216;autodetect&#8217; &amp; click &#8220;OK&#8221;.<br />
10. Right click on &#8220;Secondary IDE channel&#8221;, select &#8220;Properties&#8221; and repeat step 9.<br />
11. Reboot your computer.</p>
<p>WindowsXP should now boot REALLY faster.</p>
