Thank you very much!

I don't mind being a guinea pig. This machine is a "just for fun"
machine anyway. I picked it up for $10!

I was going to use either an old Sparc LX or a 486-DX4 100.

I'm not at the machine right now. but as soon as I get to it, I'll
get you the information.

I've only used local video. I have not yet tried serial console.

I tried booting with this kernel and my machine did nothing.

There is no OpenFirmware-like interface, as far as I know. I can get
into something that resembles a PC BIOS, and do some things in there,
just like a PC.

I'll try that out. Which program should I use for communications?
Kermit, minicom, anything else?

I see what I can come up with.

I'll get you this info too.
Thanks for your help! I thought I was going to have to tackle this on
my own.
