overflowed source buffer ... segment exceeding memory

[Bill Rugolsky Jr.]

I'm still trying to get LinuxBIOS booting on my Tyan S2462 board,
and encountering some problems.

This is with mkelfImage-1.17, binutils 2.13.90.0.2, etherboot-5.1.0.eb1,
and LinuxBIOS from CVS.

[ Building the LinuxBIOS CVS tree requires:
  perl -ni -e 'print if !/secondary\.inc/' src/mainboard/tyan/guiness/Config
  perl -pi -e 's/w832627hf/w83627hf/' src/mainboard/tyan/guiness/mainboard.c
]

What I've done is produce a "normal" and a "fallback" romimage, catenated
them together, and written the whole 512kB to the flash chip. 
[ At first glance I couldn't grok the whole fallback logic. ]

Normal:

option USE_FALLBACK_IMAGE=0
option ROM_SIZE=524288
option ROM_IMAGE_SIZE=65536

Fallback:

option USE_FALLBACK_IMAGE=1
option ROM_SIZE=524288
option ROM_IMAGE_SIZE=45056

I tried several kernels with/without ramdisk; same results.
At this point the sun was coming up and it was time to go to work. :-/

The boot log follows.

Regards,

	Bill Rugolsky
