hello folks so here's what i did: i edited the txtsetup.oem to make it look like this: # # TXTSETUP.OEM for HPT3xx UDMA/ATA100 RAID Controller # [Disks] d1 = "HPT3xx ATA RAID Controller Driver Diskette", \Disk1, \ [Defaults] scsi = hpt3xxXP [scsi] hpt3xxXP = "HighPoint HPT3xx ATA RAID Controller (WinXP)", hpt3xx [Files.scsi.hpt3xxXP] driver = d1, hpt3xx.sys, hpt3xx driver = d1, hptpro.sys, hpt3xx inf = d1, hpt3xx.inf, hpt3xx [Config.scsi.hpt3xxXP] value = "", Tag, REG_DWORD, 1 value = "Parameters\PnpInterface", 5, REG_DWORD, 1 [HardwareIds.scsi.hpt3xxXP] id = "PCI\VEN_1103&DEV_0005","hpt3xx" id = "PCI\VEN_1103&DEV_0004","hpt3xx" then i copied the XP directory from my drivers disk to $OEM$\$1\driver\raid the txtsetup.oem resides there as well. then i added the following to my winnt.sif: [MassStorageDrivers] "HighPoint HPT3xx ATA RAID Controller (WinXP)" = "OEM" "IDE CD-ROM (ATAPI 1.2)/PCI IDE Controller" = "RETAIL" [OEMBOOTFILES] hpt3xx.cat hpt3xx.inf hpt3xx.sys hptpro.sys TXTSETUP.OEM I'm not sure about the winnt.sif part actually... So far so good. my question is now: is this correct, is this going to work? i'm asking because i read several sources and they didn't agree to each other 100% so i did what i thought that should work. thanks in advance kokett
