I ran across a little problem I thought I would throw at you and
see what you think. It concerns the ST506 side of the 2090A.
I have a Kronos controller hooked up to an ST157N, and I boot
off it, and use it as my primary drive. Okay fine.
I then added a 2090A in an empty slot, and hooked the Rodime
3055 to it, and a old 10 meg ST412 drive in an external box.
The system boots up fine, and I can see and use all the drives
with no problem. BTW the 2090A thinks it is a second controller, and
assigned the drives an address of DI0: and DI1: respectively.
That's okay with me.
Now, if I do not power on the external 10 meg drive and try to boot,
the system hangs apparently waiting for the drive to come ready.
If the system is booted, and I power off the external 10 meg drive, the
internal Rodime shuts itself down.
I do not mount these devices from s/startup-sequence or s/startupii.
I removed the auto-boot ROMs from the 2090A.
I would like to be able to boot without powering on the external
drive, as it is really just work space.
Any ideas are appreciated.
