I'm sorry I didnt give enough information. I guess I was hoping some one had already done the same thing with this card. I understand VirtualPC doenst emulate my hardware. Alright. First I am installing Windows XP Professional SP 2 from CD. I am trying to modify the TXTSETUP.SIF in the i386 directory, as well as the WINNT.SIF. Here is the list of my drivers: WIN2000\AAR1210.CAT WIN2000\AAR1210.SYS WIN2000\ADHRAID.CAT WIN2000\ADHRAID.INF WIN2000\OEMSETUP.INF WIN2000\TRANS.TBL HRAIDSK1 TRANS.TBL TXTSETUP.OEM I put the in directory: $OEM$\$1\DRIVERS\RAID\AAR1210 while also taking out the ones in the WIN2000 directory and putting them in this directory as well. Its redundancy put I'm unsure how it works. I put the AAR1210.SYS file into the \i386\ directory. Here are my entries in TXTSETUP.SIF: [HardwareIdsDatabase] PCI\VEN_1095&DEV_0240 = "aar1210" [SourceDisksFiles] aar1210.sys = 1,,,,,,_x,4,1 [SCSI.Load] aar1210 = aar1210.sys,4 [SCSI] aar1210 = "Adaptec SATA RAID 1210SA" Here are my entries in WINNT.SIF: [Data] AutoPartition=0 MsDosInitiated="0" UnattendedInstall="Yes" [Unattended] UnattendMode=ProvideDefault OemPreinstall=Yes OemSkipEula=Yes DriverSigningPolicy=Ignore OemPnPDriversPath=drivers\RAID\AAR1210 im unsure what the DOSNET.INF file does Thank you for your help once again.
