Summary: Same on 3B2/600's


We had the same problem with a 300Mb ESDI from Priam (Priam 638),
attached to a 3B2/600 via a SCSI and the AT&T SCSI/ESDI bridge
controller.  On powerup, the 600 polled the SCSI host and found the host
OK, but the drive interface electronics came up too slowly, and the system
didn't recognise the disk.  Priam have since changed their controller
electronics, and the problem has gone away.

A work-around (for anyone with the 'old' controller ) was to insert a
non-bootable floppy in the 600 floppy drive (causing the 600 to hang),
leave it there for 1/2 seconds (while the 300M disk sorted itself out)
then remove it. The 600 *then* went into SELF TEST, etc, and recognised
the disk when it (the 600 booted up).
