It appears that I may have jumped the gun a little on my recent posting
concerning upgrading to ROM BIOS 1.43. My long-awaited hardware reference
manual came today, and it contains lots of interesting information about
hard disks and controllers and other related stuff.

Apparently there is a jumper (labeled W3) on the Western Digital controllers
that enables/disables the ROM on the controller card. On my disk controller
this jumper is missing (the solder pads on the PC board are connected by a 
trace, which causes the controller ROM to be enabled). 

It appears that all I have to do to enable the ROM routines on the mother-
board is cut this trace, install shorting blocks for the appropriate drive
type, and set the DIP switch on the motherboard (switch 3 in bank 1) to 
select internal BIOS code for the hard disk.

Before I go hacking up one of my PC boards, can anybody confirm or deny that
this procedure will work? I should point out that it is sufficient to say 
"I did it on my PC 6300 and it worked for me" - I promise not to hold anybody 
personally responsible if they say it will work and it doesn't. I just want 
to make sure that I'm barking up the right tree. Thanks.
