It looks like those are all x86 drivers. I tried a 'slightly' different driver: ahcix64.sys (not ahcix64s.sys). This one had an associated txtsetup.oem file, so I used that to integrate via nLite, and the boot stopped at a new screen: file ahcix64.sys not found. This is where I downloaded the driver: http://www.drivers-software-download.org/d...068-for-xp.html

Right, right. Well, which drivers do you suggest that I try to put into my genuine XP x64 disc? The one I've been trying doesn't have a txtsetup.oem, I assume because it is a PnP driver. Does this mean that it is certainly not the correct driver? Do I need to acquire another [free] driver? If so, could someone give me a hint? Do I need to have the atapi.sys or ataport.sys to load XP onto this SATA drive? I thought that those are on the XP disc. ? Thanks for your continued patience with me.

There is no such option in this pc's bios. I did find an 'authentic' (MSDN) download of XP64, and put the ahcix64s.inf driver into a fresh image of it with nLite. Install stopped at the same point: Stop: 0x0000007B (0xFFFFFADF976323C0, 0xFFFFFFFFC0000034, 0x000000000000000, 0x0000000000000000) Does anybody concur that I'm trying to insert the correct driver for this situation, or should I be scouring the net for something else? I haven't gone through all the links on this page yet [ http://forums13.itrc.hp.com/service/forums...hreadId=1254700 ] but it does show that somebody has put XP32 on

No. The only useful BIOS option is that I can choose to boot from a USB diskette key/USB hard drive. HP is a little control freakish? It still seems to me that the ahcix64s.sys (et al) is the correct SATA Controller Driver. Does anybody else have an opinion on that? If this is the correct driver, all I need is a true XP64 disk, and I need to integrate this amd64 driver into this disk (which I don't seem to have?) Thanks,

Howdy, all. Thanks for the nice forum, and for helping me out. I just got a laptop with Vistax64 Home on it and I want to "downgrade" to XP x64 Pro. I downloaded a supposedly untouched iso of XP Pro x64. I burned it and tried to install it, but it hung up with "STOP: 0x0000007b ...." error check your hard drive for errors and try again. Well, chkdsk found nothing wrong with the hard drive, and finally after looking about, I realize that that error is probably coming up because I need a SATA controller driver because XP doesn't have one on the install CD. Hmmm, having no floppy drive to
