This actually makes me wonder what do I really want.

My inital dismay from the BIOS came after I got new computer to be
the server. It was just MB/CPU/Ram/HDD. no floppy, no cdrom. I also
don't have eprom for nic (to make it netbootable).

Problem 1: took hdd to other computer and installed Linux there.
Putting it back, it comes out this bios insist to use CHS
instead of LBA like other did, so no go. Few other tries
but still no go. If I use LBA with the 'server' MB it will
declare my hdd to be 528mb (instead of 8.6gb) and confuse LILO.
Bad BIOS, bad.
Problem 2: I have an 3.5 floppy. I did attach it in the middle of cable
(ie as "B") and try booting. Two bugs this time: a) BIOS
allows you to boot off it only if you cfg it as "B", the
'swap floppy' does not work. b) Red Hat assumes that you boot
off A) drive (fd0) so even if you boot off fd1, it still will
want supplementary floppy in df0 even if there is no such device.
Bad BIOS, bad.
I ended up putting Debian which was smart enough to ask each time
what device I want to use. (I did not have Linux bootable CD's)
Problem 3:
It is ATX mb. Thus by default if power goes out and comes back it
stays off (unlike BAT mb). I'm told there is setting in bios
(APM section) to change that. My bios does not have this option.
Bad BIOS, bad.
