Hi,

I'm trying to install a SCSI fuji 2266SH (1.2Gb) on a DECstation-3100.
The drive has 512byte sectors.

The drive is recognized by ``test -c'' in the prom and by the 'scsi'
prom commands. I can probe it, and can run read/write tests on it with
no problem.

However, when attempting to boot, the drive isn't recognized. It
doesn't even come up with device name 'unknown' -- it just probes the
drive (light goes on) and then skips over the RZ entry.

I tried booting with the Ultrix 4.1 tapes, and it gave me some message about

	(1) SCSI communiction XXXXXX ID = 1, SOMETHING = 0x12
	(2) SCSI bus reset
	(3) message (1) repeated

message (1) is garbled here because the display clears immediately,
and then you need to reboot from TK50, a pain unto itself. A ``press
return to reboot'' message would be nice here, DECdudes.

So, has anyone seen such a problem before? Any possible fixes? I'll
list the disk configuration below -- it's derived from descriptions in
the manual. Cable lengths seem reasonable, but I'll double check that
if nothing else.

SCSI ID					= 1 

SCSI Time monitoring			= enabled (def)

Read ahead (256K)			= enabled

SCSI level				= tried both 2 and 1/ccs

Message mode				= SAVE DATA POINTER issued for
					  disconnection after xfr

MODE Select				= check condition status not reported

PER default value			= 0

Motor start mode			= start on powerup

SCSI bus parity				= enabled

synch mode xfr rate			= 0.96 to 4.8Mb/s

sync mode data transfer request		= enabled

SCSI time monitor mode			= ACK signal wait is unlimited time
					  Selection monitoring time is
						250ms, 128 retries (def)

UNIT Attention condition		= SCSI standard
					  (for command other than INQ,
					   REQ SENSE or PRIO RESERVE,
					   respond with 'CHECK CONDITION')
