[ This is a second post. I don't know what happened to the first. ]
I am trying to help someone out with a problem. He is trying to boot
a large kernel on a SCO Xenix 2.3.2 386 machine. WHen the kernel is
too large, the bootstrap program (boot) seems to start to load the
kernel and then silently retruns to the boot: prompt. The size of his
kernel which boots is:
288588 + 79648 + 207960 = 576196 = 0x8cac4
while the one that doesn't boot is:
288588 + 79648 + 208680 = 576916 = 0x8cd94
I made a large kernel that wouldn't boot. I was running SCO Xenix
2.3.3 on a 386. The one I made would cause boot to spit out the error
message:
invalid xs_rbase!
and then return to the boot: prompt. Its size was:
242192 + 39536 + 547828= 829556 = 0xca874
If I decreased the BSS done by 4k, it would boot.
Can someone please explain to me what the restrictions are with the
bootstrap program?
Thanks,
