actually think that is overkill. v2 by default and design
enables all of the shadow ranges as memory. So we just need to
use those ranges. That should be much easier having to patch
ADLO each time. It is fairly unlikely a writable ROM segment is
Ok.. Well when you put it that way yeah dosen't sound like its needed
at all. It should probally just work.
Wait a minute. I don't see how this will work. To do the shadows you
need to read from the bios chip, yet write to the RAM. Then re-enable
both read and writes to go to RAM. This requires you to toggle some
bits in the norhtbridge.
it is been a while but looking at loader.s
it mentions sources as 0x8000 and 0x18000, so I guess they have been
aready copied out of rom into the the low memory by linuxbios ???

I't will be awhile but I guess I will find out
when I get there. I'm
planning on still trying to use ADLO when I get V2 up and going on our
I'm looking forward hearing about results.
