I'm getting frustrated with this problem: I have a working XP Service pack 3 installation which I used to do a fresh install on my laptop. However, when I use nlite to make the installation unattended, I get an acpi.sys not found error when I try to install it. I've tried *all kinds* of different options and I get the same error everytime. I've also tried the suggestions in the other threads in this forum with no success. thanks for any suggestions!
