Hi Jeff and thanks for the reply. This was getting the best of me, so I
took another crack at it.
This installation is a new (fresh) install. No previous os loaded. Hard
drives on the Mylex, a DAT tape drive on the Adaptec. Here is what I have
I was attempting to use the bootable CD for the installation (CD connected
to the Mylex, channel 0, id #5). However, each time the error "fd(44)unix
Bad magic number" would appear after pressing enter at Boot:. (Note that
'defbootstr' does not appear to work off of the CD). So I tried the floppy
route with better success.
SCO osr 5.0.5 does indeed attempt to install the 'blad' driver even though
the adaptec is disabled in the ASUS CMOS (strange). The installation was
* on the 'blad' init, so I changed the CMOS from 'disabled' to 'auto'
and set the 'Use AHA First' option to 'no', this let the Mylex bios install
first on boot and then the adaptec bios.
Using the defaults at Boot:, the adaptec 'blad' driver loaded, then the
Mylex (mdac) driver attempted to load and panicked the system. So I decided
to use the older 'mdac' drivers that came with the board using the boot
command: 'ahslink', then 'mdac' as the driver name and 'r'eplaced the
original driver when prompted. The system booted just fine. Both
controllers are setup as 'ha0' each with their own driver.
The system has been running for a couple of hours now without any errors.
So for now all is right with the world.
