    First thing you'll need to do is replace the CMOS battery (without that, any changes you make to the CMOS/BIOS would be lost when you power the machine down).

    If you can find either, Win95 B &C (2.1/2.5) were far less problematic than the originals (95/95A).

    A better suggestion might be an nLighted version of Win2k. Cut a copy to install on a 486DX4-100/64MB. Usable, as long as I don't push it too hard.

    Win98 is pretty much a slug on a 486. Already tried (and reverted back to Win95). MS "minimum" requirements are a 486-66/16MB and realistic minimum is a P120/64MB.

    If you're thinking of jumpering over the resistor, you may damage the keyboard port circuit or other circuit. Best to determine the value of the resistor and replace it.

    And there's no reason you couldn't replace radials with axials (or vice-versa) either, as long as the leads are long enough and there's not any issue with clearance.

    Shouldn't be a problem. Make sure you observe correct polarity when replacing. As long as a capacitors stated voltage is equal or greater (up to a point), then it theoretically should work.
