hey all. just dropping a note here that I'm having a problem getting the doc2001 module(s) to recognize a diskonchip millenium being placed in the old motherboard bios chip socket.
seems I have to induce a kernel oops to get the diskonchip recognized.
i've already emailed the problem to the mtd mailling lists and david mentioned something about using a memory map module prior to loading.
so my installation of linuxbios has been stalled. basically, on reboot, the both boxes act similar to as if there is no bios chip installed. also have the docipl + 440bx support issue. As a work around tho, I plan on buying spare bios chips. However, mtd is still buggy. So far, openbios/devbios is the only thing that will actively let me read/write to the device.
(Tyan Tiger 1832DL 440BX with a second 440BX board laying around. Both with the same problem. So much for spending the extra buck on intel boards to ensure compatability eh?)

OK, you could try enabling the flash write from the setpci command, and then using MTD.

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 device).
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.
