Seagate ST-506 DIP switch settings needed - test-drb@ccmp.vtda.org

27 Dec 1998

O.K.  I already LLF'ed it, but that was with the wrong jumper settings, so
it probably didn't do much good.  I'll just have to find another 360k disk
somewhere to copy DEBUG off of my 5170.

 Probably no great point in that.  FDISK cannot usually
see an ST-506/412
interface HD that has not been low level formatted on the controller in
use at the time. Set the switch for the appropriate cable, and power up
the computer.  Bring up DEBUG and at the '-' prompt, enter DC800:0<CR>.
If you see ASCII text that indicates that you are looking at a WD
controller, then enter G=C800:5 and follow the prompts to low level
format the disk.  If this is successful - if the disk is good - then
FDISK should see it on the next bootup and you can go on from there.

If it is not successful, you probably have a bad HD.  Also, if your
DC800:0 search does not yield ASCII, try other addresses in 200H
increments.  That is, such as CA00:0, CC00:0, etc.
