Just curious if there's a "most likely" reason here for this message. I am going to clear the CMOS later, though it did not have a battery when I received it so it should already be cleared. I have checked the jumpers for the CPU settings and they appear to be correct. I have not checked the jumpers for the installed cache yet, so I'll check that later as well. What else should I specifically be checking?

Ok I just did another search since I didn't specifically look for "CMOS display type mismatch" and I guess maybe that's it? Forgive my lack of knowledge here but I didn't get into computers until the late 90s so I missed the 486 era. I've never had to set the display type, I assume that's in the setup? Does the setup retain settings even with no CMOS battery installed? The video card is a Diamond Stealth 3D 2000 PCI.

Yes it lost its CMOS settings. No it does retain settings with no battery. You need to install a battery and set the BIOS options, when your keyboard arrives.
BTW: some older PS2 keyboards will work with a PS/2 Female to AT Male Keyboard Adapter.

Yeah I know about the adapters, I don't have any of those either 🤣. It's alright though I wanted a legit AT keyboard anyway for this PC, got one for a good price NIB and it's on the way.
