Steps to do:

1. First of all it is absolutely necessary to create Vista Recovery DVDs!!!!

2. be sure there are the XP device drivers

3. Download the drivers from hp for intel (sp37005.exe) or amd (sp39719.exe)( Intel SATA AHCI Controller Driver or AMD SATA AHCI Controller Driver )

4. Create a “SATA” directory and unpack the driver file downloaded from hp in it..
If the “SATA” file, is an EXE file, unpack it with the command:

START -> RUN -> CMD

C:\sata\FILENAME.exe -a -a -pc:\sata

This command is a sort of fictional installation that does not write anything on the system.

5. Download and install NLITE

6. Create a “XP” directory and (copy) unpack the ISO cd within the same directory.

7.Create also a “XPnLite” directory, where NLITE will create a bootable modified XP image.

Choose “ALL” to confirm the inclusion of driver and when the list of driver it appears, choose “Driver Textmode”. Hold on the CTRL button and select them all.

13. Press OK

14. When Nlite has developed and calculated the size of the new Iso, press Next
