I've been trying to get a Maxtor LXT-200A to work in my Dell System 310. Ole Juul showed me ANYDRIVE.EXE, which lets any hard drive work with any BIOS, since mine isn't listed in the list of availlable hard drive types. When setting up ANYDRIVE, you're supposed to set a hard drive type that has lower settings than the actual hard drive in the BIOS. However, I accidentally set one higher than mine, and now ANYDRIVE won't boot to my hard drive. Even worse, it doesn't give me a choice to get back into the BIOS. I've tried disconnecting the clock battery, but somehow, it still retains the settings. Question is, could I somehow "reset" the computer so I can get back into the BIOS?

If you can boot from floppy, try using the GSETUP diskette (search the forum for it).

If you can get into debug, try this (your keystrokes are boldface):

-a100
1407:0100 mov al,10
1407:0102 out 70,al
1407:0104 mov al,ff
1407:0106 out 71,al
1407:0108 int 3
1407:0109
-g=100

AX=00FF BX=0000 CX=0000 DX=0000 SP=FFEE BP=0000 SI=0000 DI=0000
DS=1407 ES=1407 SS=1407 CS=1407 IP=0108 NV UP EI PL NZ NA PO NC
1407:0108 CC INT 3
-q

Note that the addresses will be different on your system.

How was it able to retain the settings even though I removed the battery and had it unplugged?

Different motherboards have different requirements for how long the battery needs to be removed for.
I'm sure that I've encountered motherboards where the battery had to be removed for 5 minutes or more.

Some motherboards have to short the battery terminals (after the battery is removed) for 15 seconds or so to clear the CMOS. Low-power SRAM can be quite tenacious.
