I have been trying to connect a Fujitsu M2261SA disk drive
to the SCSI bus on a 2500. I set the drive to SCSI address 4 since
there is an internal drive at address 6 and another external
drive at address 5. The DEVS command in the mnenomic debugger
finds the drive at address 4 OK. However, when the
mnemonic debugger TE command runs, it hangs up. The last line
displayed is "STORAGE LOAD PATH SELF TEST STARTED". (The
next line should be SCSI Chip test PASSED.) The LED on the
disk drive lights and stays lighted. I have tried some
jumper changes on the drive, but nothing made any significant
difference. Does anyone know how to make this combination
of drive and computer work?
Thanks.

CN9:

Some of the jumper changes I tried (one at a time):
SCSI-1 instead of SCSI-2
Disable SAVE DATA POINTER message
SCSI bus parity check disabled
UNIT ATTENTION does not respond with CHECK CONDITION
--none of these made any difference
I also tried changing the ACK wait time from unlimited to
30-60 seconds. This resulted in the light on the drive
going off after 60 seconds so apparently the drive is
waiting for an ACK for something.
The drive was sold to be used with a Macintosh.
