I'm running a Turtle Beach Malibu, which seems unaffected, but it does prompt me to hit F1 for a voltage error when I boot, which is irritating. That does sound annoying. If the motherboard's really not using the -5v for anything but to measure then you might be able to trick it with just a …

You're not likely to run into ISA cards with -5v requirement on a PIII system. The most prominent cards I can think of are one of the 8-bit Sound Blasters (which one I don't recall exactly, maybe 2.0?) and maybe the SB Pro 1 but I could be wrong about that. If I had to guess, you're probably looking …

I like 5:4... Maybe it's just because I'm used to it. Basically every XP machine I ever interacted with that had a good monitor was 1280x1024. XP looks perfectly at home on those goofy almost-square LCD monitors. Of course in a perfect world we would have just gotten 1280x960 LCDs and in that world …

Fascinating. Interesting that the FSB bottleneck at high mult is significant enough that the cache reduction makes that big a difference.

With Slot 1 it should be pretty easy to try both and check. That's one of a small number of reasons I do like the slotted form factor. Cooler comes away with the cpu, no need to fool around with coolers or thermal paste when you swap as long as both still have coolers.

1GHz celeron w/100MHz FSB is extremely likely to slap around a 750MHz PIII w/100MHz FSB for games. Having twice the cache will not save the PIII from the fact it's only running at 75% of the clock speed of the celeron.

EMS can be nice for some things. A 386 can simulate it through EMM386, but hardware EMS is always faster.

Memory expansion card may be an EMS card. If so, the RAM on it wouldn't be counted at startup, just by programs that used it.

You're not going to damage it by using it, and even if it did stop working, it'd be worth probably almost as much money still.
