yes. i started researching setpci data and the addresses to mingle with
are probably addressed in the openbios/devbios project as "devbios" does
apparently allow writing (including reading) the bios chip -- but not
the mtd doc -- this is probably why a kernel oops allowed the setpci
address to not be reset (or turn-off write access) before unloading the
devbios module. ...very possible.
however, once I'm able to do this, the problem is, how to get the DOC to
be recognized via linuxbios on a machine cold start? I'm guessing some
changes will have to be introduced into the mtd kernel drivers (setpci
write enable on the intel 440bx board before attempting to mount the mtd
I'm guessing the best thing to do is to probably buy extra original
motherboard bios chips first. then once there's a successful boot, then
try converging stuff to a DOC.
well. i will continue to dabble into this -- but the sun is *finally*
out in San Diego... finally.
