I have a question regarding an old full-length Western Digital
controller (WD1002S-WX2 Revision "C" circa 1984) and a brand new
Seagate ST-225.

Apparently the two don't like each other.  It screws up one of our
Zenith 158s so badly that it won't even boot off the floppy.  A "1701"
error message appears on boot (general hard disk error) and the A:
drive light just flashes on and off continuously.  I can't even boot
the machine to access debug to do a low level (via "g=c800:5")!  (Of
course, the machine will boot when I disconnect the power going to the
fdisk.)

It was my impression that these two got along with one another.  The
disk that I'm replacing is an old half-height 5.25" 20 Mb labelled
"CSA Model CM 3426".  (I didn't know the Cub Scouts made disks...:)

What do I need to do to get these two running?  I've got a half-length
WD1002A-WX1 controller with Zenith firmware (ROM #444-607), but I
don't want to use Zenith's DOS (and CONFIGUR program) to set it up.
I've got MS-DOS 4.01 all ready to go...

Anyone know how to use debug to access the firmware on this card?

Thanks for your help!
