I have had a lot of answers to my first question about an age old problem of HD capacity issues with earlier versions of XP. I have found that my Dell copy of XP Pro seems to have SP1, but that doesn't really matter for this question. I have created a slipstream with nLite putting XP and SP2 together and made a direct burn from that program. I tried to make an install from that CD and it started loading drivers and after awhile it stopped with an error of usbehci.sys is missing or corrupted. Any ideas of where I went wrong? I read some articles about slipstreaming SP3 and it seemed slightly more complicated than SP2. I figured I'm doing something wrong during my slipstream that is causing this problem.

I'd guess it was a bad burn. but could really be alot of things.  burn these disk at half the speed the media is rated for and have it verified by the program.  That should take care of corruption issues.  You could also try putting in your orginal disk to see if it will pull the file from there.

I burned it at 16X and I believe it is a SP2 sys. since I couldn't find it on my disk. It was on the SP2 though. I didn't verify it though so I might try that.

Does anyone know how to slipstream an XP SP2 (XP that has SP2) with SATA drivers (for e.g., from the Gigabyte site)?  
 
Most writeups are for XP that needs SP2 added.   But, I have SP2 already and would just like to add the SATA drivers so I can use AHCI mode.  
 
Adding/slipstreaming SP3 is interesting but I think if I can learn how to do the more common XP SP2 w/ drivers, then I can try that later.

I guess you could try nLite and see if it would allow you to add your drivers. Never needed to add my drivers for a HD though. In fact, the last HD I got from Seagate didn't even have drivers.
