First of all thanks for the guide. I'm not sure if you have got this to work, I tried it, but I'm getting an error message and was hoping someone could help me with it. (txtsetup.oem caused an error (18) at line 1742 in D:\xpsp1 ase\setup\oemdisk.c. Press Any Key to Continue) I will paste the lines that I think are important so you guys can take a look at them if you have a chance. this is my txtsetup.oem file: ---------------------------------------------------------------------------- # # TXTSETUP.OEM for HPT374 ATA RAID Controller # [Disks] d1 = "HPT374 UDMA/ATA133 RAID Controller Driver Diskette", \Disk1, \ [Defaults] scsi = hpt3742XP [scsi] hpt374XP = "HPT374 UDMA/ATA133 RAID Controller for WinXP", hpt374 [Files.scsi.hpt374XP] driver = d4, hpt374.sys, hpt374 driver = d4, hptpro.sys, hpt374 inf = d4, hpt374.inf, hpt374 catalog= d4, hpt374.cat [Config.hpt374XP] value = "", Tag, REG_DWORD, 1 value = "Parameters\PnpInterface", 5, REG_DWORD, 1 [HardwareIds.scsi.hpt374XP] id = "PCI\VEN_1103&DEV_0008","hpt374" This is part of my winnt.sif file: ----------------------------------------- [OEMBootFiles] hpt374.sys hpt374.inf hpt374.cat hptpro.sys TXTSETUP.OEM [MassStorageDrivers] "HPT374 UDMA/ATA133 RAID Controller for WinXP"="OEM" I have placed the following files: hpt374.sys hpt374.inf hpt374.cat hptpro.sys TXTSETUP.OEM in these 2 directories: cd:\$OEM$\Textmode cd:\$OEM$\$1\Drivers\Storage I hope I posted everything thats important in troubleshooting this, if not feel free to PM me with any questions.
