Dave, I'm pretty loaded at this time (but who isn't), we can work
on things. We have board (custom data acquisition system) which
is very close to AMD eval board, without Keyboard, VGA...etc,
but with bunch of custom FPGA, SRAM etc...
Currently I run qnx on there and it SUCKS. If there are other people
on net who want to do BIOSless/Diskless Linux thing, let's
do it, we can do it in more or less generic way, so PC104
people will be able to reuse code....
At this moment I have real mode init code, switch to protected
etc, can easily load any image to dram and jump to it.
Missing pieces:
1. Clean Setup.s, we need to #ifdef all VGA etc stuff from there.
when I was playing with stuff, I just deleted out code
that I don't need.
2. Initial Flash/ROM file system, I saw very reusable code
in pcmcia drivers source code.
Overall Flash structure is:
0 - ?K - kernel image
?K - FK - file system image
FK - - initial_loader
Aliased 0xFFFFFFFE (look in book for aliasing) - jmp initial_loader
