All you need is FASTTX2K.SY_ in your I386 folder and the following added to your TXTSETUP.SIF file: under [sourceDisksFiles] fasttx2k.sys = 1,,,,,,4_,4,1,,,1,4 under [HardwareIdsDatabase] PCI\VEN_105A&DEV_3319 = "fasttx2k" PCI\VEN_105A&DEV_3371 = "fasttx2k" PCI\VEN_105A&DEV_3373 = "fasttx2k" PCI\VEN_105A&DEV_3376 = "fasttx2k" PCI\VEN_105A&DEV_6629 = "fasttx2k" under [sCSI.Load] fasttx2k = fasttx2k.sys,4 under [sCSI] fasttx2k = "Promise FastTrak 37x/S150 TX4000 Series Controllers" That should be all you need for it to be recognized during installation.
