Are you rebooting from RAD: or from floppy? I've found that there's a timing thing involved -- I have had to move the binddrivers command to the first line of my Startup-Sequence (even before FastMemFirst or SetPatch) in order to boot reliably, but then I'm rebooting from floppy disk; the timing may be different if you reboot from RAD:. While I was adding my SCSI drive, I was trying to run off my ST-506 drive. This turned out to be fatal; the first time I rebooted after PREPing the SCSI drive, the system only came up about half-way through the boot script and then GURUed. At that point, the ST-506 drive was trashed, and I could not even run BindDrivers so that I could mount \either/ drive in order to format it. I eventually had to remove the ST-506 drive, format the SCSI drive, remove the SCSI drive and put back the ST-506 drive so that I could format it, and only then would BindDrivers ever bind with both drives. And it was still unreliable, as I've indicated above; if the timing on a boot-up isn't just right, it still hangs. If anybody can explain what to do to fix this problem, please let me know. -- -- Greg Noel, NCR Rancho Bernardo Greg.Noel@SanDiego.NCR.COM or greg@ncr-sd
