Hi John,

It seems to me that eisa was an extension to isa and that most modern 
computers don't have an isa bus but have eisa bus instead, In fact I 
have a Gateway Computer (500Mhz PIII) that has an eisa slot on the MB. 
Actually most modern computers don't physically have a slot for either 
isa or eisa. Quite possibly either one would work. I have 'device eisa' 
in my conf, it's also 'device eisa' in the GENERIC conf which is why I 
mentioned it.

I also have a memory of APM and ACPI being incompatible - I think that 
was from the early 5.x days, not sure, could be from earlier. But 
commenting out "device apm' certainly wouldn't hurt since he's probably 
going to have to rebuild anyway.

I think I would also ask: is he trying to do a custom kernel with 6.0 
release sources or 6.0 stable sources? When I went from release to 
stable things worked.

Other things can affect what he's trying to do and cause him to think he 
has an ACPI problem. I had a bad USB mouse that was causing problems on 
one of my computers, in fact anything USB on that computer caused a 
problem with ACPI (it had to be disabled to allow the computer to 
boot-up) if that mouse was plugged in, until I found the mouse was bad 
and switched it with one that was ok. On another computer, I could only 
boot-up if I either disabled ACPI or had the USB mouse unplugged. After 
it was up, the mouse could be plugged back in and it would work, ACPI 
would work, but I would be left wondering about the situation. I 
finally decided to just use a PS-2 mouse and wait a while. That works 
fine, although I hate ball mice.
