1. Creating the Windows XP Boot Image<br />1<br />Set your BIOS so that USB booting is enabled. (Your BIOS must support boot from USB.) Connect the USB external hard drive directly to your computer.<br />2<br />Make an ISO image (an .iso file is an archive disk image of an optical disk) from the Windows XP CD-ROM using your preferred software. Save to your hard drive.<br />3<br />Open the ISO file you just created. Navigate to the I386 folder, and select the following files:TXTSETUP.SIF, DOSNET.INF, USB.IN_, USBPORT.IN_, and USBSTOR.IN_.Extract the files and put them into a folder to work with.<br />4<br />Open a command prompt and use Cab SDK to extract the contents of the .IN_ files; Cab SDK is a Microsoft compression and decompression program available as an .exe file in your Windows directory. Each of the .IN_ files contains exactly one .inf file. An example command line would be: quot;
cabarc x USBSTOR.IN_quot;
. You should end up with three new files in the folder, called usb.inf, usbport.inf and usbstor.inf. Delete the .IN_ files.<br />5<br />Open the files using a simple text editor such as Notepad. Edit them according to the section below titled quot;
Editing Files.quot;
<br />6<br />Open the previously created ISO file and delete the files you extracted earlier. Replace them with the newly modified files.<br />7<br />Save the ISO files and burn them to a CD using the burning software of your choice.<br />8<br />Insert the CD you created and restart the computer. Make sure it is set to boot from CD. Most computers will do this automatically, but if not, hit F8 on startup to choose boot options. When asked, choose the external USB hard drive to install WIndows XP.<br />Editing Files<br />1<br />Open TXTSETUP.SIF and move the following entries from [InputDevicesSupport.Load] to the [BootBusExtenders.Load]:usbehci = usbehci.sysusbohci = usbohci.sysusbuhci = usbuhci.sysusbhub = usbhub.sysusbstor = usbstor.sys<br />2<br />Move the following entries from [InputDevicesSupport] to [BootBusExtenders]:usbehci = quot;
