Hi all, I've added three lines to the txtsetup.sif file of my Windows XP install CD: [SCSI.Load] wvblk32 = wvblk32.sys,4 ... [SourceDisksFiles] wvblk32.sys = 1,,,,,,,4 ... [SCSI] wvblk32 = "WinVBlock Driver" It successfully loads during setup, but the wvblk32.sys driver also gets installed as a "Boot" service in Windows, which is not what I want. In order to prevent this from happening I tried grasping at a few straws: Different combinations of flags in the [sourceDisksFiles] "wvblk32" entry Adding 'wvblk32" to [NetServicesToDisable] section Adding "wvblk32" to [RootDevicesToDelete.clean] section None of which prevent the driver from being installed. Some of the default [sCSI.load] entries (such as cpqarray) are not installed after setup is complete, so I think it should be possible. I just can't figure out how. Any help from the experts would be greatly appreciated! Cheers
