I'm having a lot of problems booting with real-base != -1. This is on a
beige G3 with I think a rev A rom (will check).

Actually, this machine is rather freaky. I'm net booting it.

I have an ofwboot.xcf which was compiled to load at 0x600000. If I set
load-base to 600000, I can't net boot - I get a CLAIM-FAILED in the data
segment. BUT if I set load-base to 6c000000 , it works.

???

Then, if I set real-base to say f00000 or f0000000 , then I can boot a
large kernel. BUT the next time I go into OF (say the next boot), OF
wedges hard. I get a chime, but nothing shows up on any
screen. Cmd-Optioon-P-R doesn't reset the prom either. I have to reverse
the PRAM battery for a while (or let it sit w/o battery even longer) to
get the machine back.

Any one else seen this?

Take care,

Bill
