I found your site through googling my issue and finding this thread. I think I'm having a similar issue, but I tried what it said in that thread, and was unable to fix my issue.

I just purchaced a completely new computer(well, parts), that includes:
Pentium D 940 Pressler
ASUS p5WD2-E Premium Mobo
Kingston HyperX DDR800 1GB Ram(x2)
Western Digital Caviar 250GB SATA 3.0Gb/s HD's (x2, I want to do Raid 0 eventually).

Upon trying to install windows(off my XP non servicepacked install disk), I go through the loading drivers screen(and load the sata drivers off a floppy as well), and it errors on PCI.sys. I tried creating a slipstream disk using the latest version of nlite, but the disk I made wasn't recognized as bootable.

Here are my issues:
upon installing, I get this:
STOP: 0X0000007E (0XC0000005, 0XF748E0BF, 0XF78DA208, 0XF78D9F08)

pci.sys - Address F748E0BF base at F7487000, Datestamp 3b7d855c

Is this an issue that can be fixed by slipstreaming a SP2 install?

And, if so, is there some trick with nlite(its different now than the version that has examples that is linked to in that thread), that allows me to create a bootable image? right now all it does it create a set of files that I can burn onto a disk that acts as a SP2 install disk, but its not boot-ready.

Any help is greatly appreciated.
