[LinuxBIOS] Problems with elfboot

[Hanoi Santos Hung]

Hi :
I'm working with this hardware configuration :
North  : vt8605
South  : vt82C686B
RAM : 128 MB SODIMM

I begin modifying the code from vt8601 and LinuxBIOS V1.0 version of
vt82c686 and I have my system working until it tries to load the
payload (filo). I think the problem was the memory, but
ram_check(0x00000000, 0xA0000);
ram_check(0x00100000, 0x8000000);

works perfectly, another symptom : when the board make a cold start it
freeze at "Jumping  to  LinuxBIOS".

I'll apreciate any help

Best Regards

Wow, 1.0 is really old. Was there no board in 2.0 that was similar to
your board? Perhaps one of the EPIA boards?

ram_check() is a _VERY_ simplistic memory test, RAM is not
neccessarily working properly just because it does not fail.

Please try to use memtest86 as payload before FILO or anything else.

Please send the full serial output you get from the board.
