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 a similar machine. Perhaps I need to take out some of the drivers that are on the original XP disk as they hinted at, while putting the proper driver in there? And the search continues...

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 load drivers at the F6 option, it seems that the easiest option is to use nLite (I've just started using, and really dig it!) and shove the driver into the XP boot CD and re-burn. My main issue is that... I can't figure out/ find which driver to use. ! I tried to add the ahcix64s.inf via nLite to a couple of boot disc burn attempts, but to no avail. It still stops at the same point with the same error. I suppose that's ok, because those useless burnt CD-Rs make for good microwave oven entertainment. Anyway, if you've made it this far in my saga, below are some possibly relevant specs from the machine. I would sincerely appreciate your help. Thanks in advance! HP actually gives a non-nLite way to accomplish the install of XP on SATA drive without floppy, but it seemed much trickier than nLite: [http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c00758841&dlc=en&product=3795407] Hewlett-Packard Pavilion Notebook dv7-1130us [http://h10025.www1.hp.com/ewfrf/wc/product?lc=en&dlc=en&cc=us&docname=c00042629&product=3795407&] [above link is the HP support for this laptop] OS [current]: Windows Vista Home Premium (x64) Service Pack 1, build 6001 MAIN CIRCUIT BOARD: Hewlett-Packard 30FC 01.54 BIOS: Hewlett-Packard F.21 07/18/2008 DRIVE: WDC WD25 00BEVS-60UST0 SCSI Disk Device (250.06 GB) [in two partitions, NTFS formatted - Western Digital Scorpio Blue WD2500BEVS] [http://support.wdc.com/product/download.asp?groupid=702〈=en] [drivers being used are disk.sys, hpdskflt.sys] CONTROLLERS: [all using atapi.sys, ataport.sys] ATA Channel 0 ATA Channel 1 Standard Dual Channel PCI IDE Controller [also using pciide.sys, pciidex.sys] BUS ADAPTERS: AMD AHCI Compatible RAID Controller [using ahcix64s.sys] AMD RAID Console [this is not being used, apparently - there are no drivers installed and it's not running] Microsoft iSCSI Initiator [for network devices, right? -nothing to do with my hdd? using msiscsi.sys, iscsilog.sys] Standard Enhanced PCI to USB Host Controller (2x) [not for hdd, right?] Standard OpenHCD USB Host Controller (4x) [not for hdd, right?] Cheers and thanks!
