Re: questions and report on setting up UMAX Apus 2000 boxes

Hi,

I dig out my Apus2000/200, and it still works.

It looks Apus2000's OpenFirmware doesn't probe CD-ROM drives
at boot time. Probably it doesn't reset CD-ROM drives or scsibus
properly so we have to reset twice to boot from the CD-ROM.

No idea, but I wonder if it's rechargable.

cmd-alt-p-r will work to initialize NVRAM variables,
but if some important variables (like real-base etc) have
fatal wrong values, cmd-alt-p-r didn't help.
(I had to remove a battery whole a day to reset them)

At least 3c905B (ex(4) on NetBSD) and SMC83C170 (epic(4)) work
on my Apus2000.

Yes, Apus2000's PCI slots are a bit fragile, and it will
really help to cleanup contacts of boards and slots.

Incomplete electrical contacts (bad data bus, address bus, interrupts
lines etc.) could cause kernel traps or silent hang before boot.

Here is a log of 6.1 INSTALL CD on my Apus2000/200:

The first time I tried I got a "can't map interrupt" error
on ex(4) attach, but it worked after cleanup.
