1) when booting linuxbios on a new machine, ALWAYS
kernel as an i386. It's just safer that way. Turn off everything you
make sure what you're doing would work on a 1990-era PC.
Tried with a pure i386-kernel, same result :(
2) always enable serial and, before you try linuxbios,
minicom on the machine and make sure serial REALLY works.
This is also a good cable test. Take nothing for granted.
It works alright! Has been running it from day one ;)
3) If it's legal where you live,
always burn a copy of the fuctory bios and boot with that,
to ensure your burn path is totally working.
Again, if it is legal where you live, keep a spare
copy of fuctory bios around for that inevitable time when you
screw up and flash over it.
I've got a BIOS-savior, and I run the BIOS in that. I don't think it will make
difference pulling the savior out and place LB in the original socket.
4) never try VGA on the first time around. It adds too
I'm not quite sure how to manage that. Everytime I've tried just leaving out the
/root/113mem.bin fallback/linuxbios.rom > ./linuxbios.rom" I end up with a
prom. Is there any other changes to be done to make it work?
5) use earlyprintk! earlyprintk=ttyS0,115200,keep
Tried that, no special output at all. ( See below. ) What I did was to make sure kernel
is compiled with CONFIG_EARLY_PRINTK=y and adding the above line to my commandline:
mkelfImage --kernel=/boot/vmlinuz-126.96.36.199-i386 \
--command-line="ro root=LABEL=/ rhgb quiet console=tty0

6) learn to use initramfs, and have it boot a simple
(I'm just getting the hang of this, but it's very useful)
(you can write a shell in surprisingly small space)
I'd love to, as soon as I can get the kernel to load at all.
7) spontaneous reboots almost always mean that
you have the wrong cpu type. See note (1) above.
very quick reboots are a good hint that memory is
getting errors. Lockups are a sign of bad memory
programming (you wouldn't believe some of the failures
I've seen) or you've got an old VIA chipset with a bug :-)
For any but the worst reboots, earlyprintk is a big help.
