    This PXE code targets the onboard Via Rhine II Ethernet. I guess it might be interesting to see if the ROM signature goes away if I disable the port. (There's no utility I see for disabling just the...

    I wasn't saying they were right, just noting that I'm not the first person to inaccurately refer to 2000 as being a minor point release of PC-DOS 7. But if hairs must be split 100% correctly I'll...

    Bingo. The byte there is 60, so it's 48k long.

    Dumping at CC00 the first three bytes are 55 AA 4C, so apparently there's another option ROM that's 38k long immediately after the video bios....

    I did some PEEKs from BASIC and there does seem to be “data” in these locations, or at least they definitely aren’t all zeros. My hope was there might be some kind of mapping/profiling utility to run...

    I guess I should find some software that hits VESA extended modes and try to trip it up. I doubt there’s any native DOS drivers specifically for this card.

    Video is the shared-memory Trident Blade 3D derivative they built into the chipset. Again, maybe I’m just out of touch thinking 96k is big for a video BIOS? Since the board does support some optional...
  7. Via Mini-ITX EPIA as a retro DOS machine: setting up UMBs?

    Inspired by a recent thread on the worst x86 CPUs ever made I've dusted off an old mini-ITX thin client I've had untouched in my garage for at least a decade and decided to see how well it works as a...

    I'd love to know what's on that white EPROM chip bodged onto the middle of the board. It looks like it's a 2kx8 2716-equivalent; if you PEEK around over the 12k mark (where ROM usually ends in a...

    Just eyeballing it I'd guess the DB9 connector is for an Atari 2600-style joystick. (Looks to me like they soldered it so it'd actuate the directional arrows and the button is the spacebar.)

    Oh, I'm not expecting it to be great, I'm mostly just curious if driving the board meaningfully from DOS works at all.

    I hope my particular board supports the DOS soundblaster driver that’s apparently floating around for older EPIA platforms. If I can make that and mTCP work I may suddenly like it. Having a Tandy...

    As an aside, this thread about the C3 just hit the magic point where it’s motivated me to dig out the fanless Eden ITX box from the junk shelf to play with. I thought of the thing as an utter waste...

    About the AIS? Have you actually found any compilers or public command references for it? I dug around and it seems like Via hasn’t done much more than publicly acknowledge it exists and that it’s...

    Transmeta definitely was.

    This paper about the "God Mode" exploit for the C3 chip is certainly interesting reading. The "Alternate Instruction Set" for these CPUs (which is what they apparently...

    That would certainly explain a lot. NatSemi must have been laughing all the way to the bank after foisting that off on poor Via.

    The K6 does do some speculative and out-of-order execution, but has a pretty shallow pipeline and it's also more limited than later processors with regards to what instructions it's capable of...

    I think the reason the C7 particularly gets under my skin is because my first exposure to it was in an HP 2133 notebook, which came out within a couple months of the first batch of Atom 270 netbooks....
