My PC is dell 9150. HD is WD 160GB SATA. SATA setting is RAID/AHCI.

As XP SP3 is out, I want to give my PC a fresh reinstall with SP3. So I find back the Dell XP CD, and slipstreamed it with SP3 I downloaded from MS, and make another CD. I did so using nLite, with no problem.

Then I start the PC with this slipstreamed SP3 CD. However, after EULA, it has problem recognizing my HD. It says 'Unknown Disk (No disk in drive)' twice in lower part of screen, and if I press Enter, it gives blue screen with 0x00000050 error on setupdd.sys.

I tried to start with my original SP2 CD, there is no problem.

I changed in BIOS the SATA configuration to RAID/ATA, then start with the SP3 CD again, there is no problem.

So it seems the slipstremaed SP3 CD has some compatibility issue with my PC. Any clue?

I searched in MS, it says ox00000050 error may be because of RAM faults. But I don't think it's the case for me as the error doesn't occur if I change SATA setting or if I use the original SP2 CD.
