Does anyone out there have an AT&T 6300 with a Western Digital controller
and ST225 hard disk(s) and the new 1.43 BIOS? We are trying to upgrade to
the new BIOS and are having problems. We have two hard disks on the WD
controller, which worked fine on the old 1.21 ROMS. We are having major
problems getting both drives to work with the new ROMS. There seems to
be some sort of conflict between the hard disk controlling code in the
new ROMS and with the ROM on the controller card itself. We've tried using
both settings on the third switch of SW1 on the AT&T. These supposedly
switch between internal (1.43 ROMS) and external (controller ROMS) control
of the hard disks. On internal control, the 6300's diagnostics recognize
that two hard disks are installed, but then says "Optional ROM at c800"
and dies. On external control, it doesn't say anything about the hard disks,
does the optional ROM message and boots up on drive C, but claims drive D
doesn't exist. What I'd like to be able to try is disabling the ROM on
the controller card and trying it on internal control. So (finally) does
anyone out there know how to disable the controller's ROM? I would hope
it would be one of the jumpers on the controller, but the pitiful docs
I got with it don't tell me sh*t. Thanks for any help.

Jumper installed ---> ROM enabled Jumper not installed ---> ROM disabled W3 is to the right of U11 with the board oriented with the connector fingers to the right and down. W3 may actually be closed (comes from factory this way) by a printed path on the board; the path must cut (carefully and cleanly) to disable the ROM. Dave Braune AT&T ihnp4!ihlpe!dpbaudra
