9) Now choose de “don’t search. I will choose de driver to install” option
10) Click next
11) Now highlight de Standard Dual Channel PCI IDE Controller
12) Click next
13) The Standard controller will install
14) Reboot and log in
15) The standard controller is completely installed

First of all, this tweak only apply to those who only have one HDD on deir primary IDE channel (nothin’ else on device 0 or 1) and a CD-ROM and/or DVD-ROM on de secondary IDE channel. Each time you boot Windows XP, dere’s an updated file called NTOSBOOT-*.pf who appears in your prefetch directory (%SystemRoot%Prefetch) and dere’s no need to erase any oder files as de new prefetch option in XP really improves loadin’ time of installed programs. We only want WindowsXP to boot faster and not decrease its performance. Channel tweak as those two tricks, coupled togeder with a little modification, result in an EXTREMELY fast bootup:

1. Open notepad.exe, type “del c:windowsprefetch tosboot-*.* /q” (without de quotes) & save as “ntosboot.bat” in c:
2. From de Start menu, select “Run…” & type “gpedit.msc”.
3. Double click “Windows Settin’s” under “Computer Configuration” and double click again on “Shutdown” in de right window.
4. In de new window, click “add”, “Browse”, locate your “ntosboot.bat” file & click “Open”.
5. Click “OK”, “Apply” & “OK” once again to exit.
6. From de Start menu, select “Run…” & type “devmgmt.msc”.
7. Double click on “IDE ATA/ATAPI controllers”
8. Right click on “Primary IDE Channel” and select “Properties”.
9. Select de “Advanced Settin’s” tab den on de device 0 or 1 that doesn’t have ‘device type’ greyed out select ‘none’ instead of ‘autodetect’ & click “OK”.
10. Right click on “Secondary IDE channel”, select “Properties” and repeat step 9.
11. Reboot your computer.

Windows XP should now boot REALLY faster.
