My FIC KA-6100 motherboard has similar specs, it's currently running a GeForce 2 without issues in DOS, though I haven't installed any games yet.

I'm waiting for a TNT2 Pro to arrive, I hear it has better compatibility with both DOS and Windows 98.

Interesting abomination, ZX, AGP slot and Rage Turbo AGP. Hopefully Rage is on PCI bus, but suspiciously a lot of tracks from it go to AGP slot suggesting it needs to be hard disabled first. Have you played with VEN_DIS jumper?

I have an ASUS P2-99 motherboard as indicated in my signature, which has the Intel 440ZX chipset and 3.3V AGP slot but without any integrated video chip. Compatible nVidia cards that I used and worked well on it were the TNT2 Pro, GeForce2 GTS, GeForce3 Ti 200 and GeForce4 Ti 4200.

It's by no means a bad motherboard. The limitations of the ZX chipset over BX hardly matter for retro use and the ISA slot means very capable dos machine.
I'd think something like a GF2 MX is a safe bet, not cost too much, nice pairing with the PIII 450.

I would also think you could probably upgrade to a P3 600 Katmai trouble free. We ran a C500 on a slocket adapter on our Ausus ZX motherboard back in the day. however ours was generic Asus.

Yeah the ZX is really nothing more than an updated LX, both locked at 66Mhz (Intel says a limited 440BX designed for Celerons <but I beg to differ on that one:D >)

To avoid confusion, there are two versions of the Intel 440ZX chipset which are the ZX-66 variant that you mentioned and the one officially supporting 100 MHz FSB without being necessarily restricted to Celeron CPUs.

This was it! I had no idea those jumpers existed and probably would have never noticed. I set both VEN_DIS and VGA-INT to disabled and after clearing the CMOS it was able to boot with the cards I mentioned earlier.

I was considering this upgrade but wasn't really sure if it would be compatible. I also noticed the pins for the FSB clock are missing 🤣. You can see it in the pic rasz_pl posted.

Yeah forgot the Slot boards were ZX-100, the soc 370's were ZX-66 like the pos Intel micro board from a Compaq, still have the celeron 366 soc370 with Intel fan but the board had issues not worth fixing since I have better one 🤣.....

zida had ZX doing reliable 100MHz https://theretroweb.com/motherboards/10673
worked with C366@550, afaik even coppermines after socket modding
I dont remember if it had fsb selection in bios (doubt) or if I was soldering pins on the back to force 100MHz (most likely as I was putting 366 in there and those needed 2.2V)

Nice ! The picture shows a standard 443ZX (the 100mhz version) and The manual shows bios setting for cpu "overclocking".
Think the board I had was this BI440ZX and was horrid: https://theretroweb.com/motherboards/s/intel-bi440zx-bimini, it is faint but you can see the -66 on the 443ZX chip in the picture...
Almost zero bios features and was def locked at 66Mhz, also had vrm issues even with replaced caps iirc
