[comp.sys.ibm.pc.rt] 3rd party drive installed - works fine

ra@sun1.ruf.uni-freiburg.de (Christoph Ramshorn) (05/03/90)

We just installed a Fujitsu M2249E hard disk (380 MB
unformatted) in our RT 6150 / EESDI adapter / AIX 2.2.1

To make it work we did the following (installing
the drive in position D or E):

We set jumpers to
	Drive select	2
	Signal gate	yes (daisy)
and removed the terminator resistor.

For formatting, we did NOT use Diagnostics, but
the VRM diskette (when it failed to start up, we removed
the diskette from the drive and then inserted it again; this worked).

For formatting, one needs to choose 
	(7) Maintainance facilities
Enter /* Drive in position E */
	format 3
or /* Drive in position D */
	format 2


Choose to specify your own drive parameters (they
may vary, we give the numbers we used):
	Cylinders		1243
	Heads			15
	Sectors/Track		35	/* Check jumpers on
					   your drive */
	Interleave factor	1
	Skew factor		0

Choose to format the disk. This will take approx. 
half an hour. Afterwards, when your system has been
restarted, the "minidisks" command will show the new
drive as "hdisk2" ("hdisk1" in position D).

You may choose to format the drive again with the
formatting option of "Diagnostics". We did so despite of
an awful lot of warnings output by "Diagnostics" and it
worked all right.

Probably other third party drives w/ ESDI interface will 
work as well. The main trick is to jumper for "drive select 2".

Good luck!
