Sorry, lets take a step back because I think I'm confusing you... What I'm trying to get at is that I know the original XP CD-ROM source to be OK. I was able to perform an installation of XP Pro using the original XP Pro CD as it is and the nforce SATARAID drivers copied to two separate floppy disks and using the F6 method at the beginning of setup. The nLite'd CD I'm trying now is using the source from the known working XP CD and has the nForce SATARAID drivers slipstreamed (by selecting Multi-Drive Folder and TextMode as suggested earlier). But the nLite'd CD I'm using also has SP3 slipstreamed into it along with a handful of hotfixes, the, IE7 and the nForce Ethernet drivers. The original nLite'd CD had all this plus was configured for a fully automated (unattended) setup. This didn't work however, and I get that "Not enough virtual memory or paging file quote to process the specified command" flash up before the system reboots itself at the very start of the GUI installation of XP. So, I made another nLite'd CD only this time took out the entire unattended section, but kept the slipstreamed SP3, nForce drivers and hotfixes (including IE7) but this CD too has the same problem (error at first part of GUI setup followed by automatic reboot of system). I've removed 1GB of RAM (so i'm now down to 1GB from 2GB) and tried the last nLite'd CD again, but still the same problem. Unless anyone can suggest the cause of this I'm going to have to go through a process of elimination. I plan to start off with the original XP CD's source and slipstream the nForce SATARAID driver, but nothing else. If that works, I will repeat the process this time adding SP3, and so on adding in all the components until I find the one causing the problem... I just hope I have enough blank CD-Rs :-)
