Can't boot without changing memory

I have an old FIC PA-2007 mobo (VIA VP2 chipset) that doesn't seem to like Infineon PC133 64MB SDRAM. I can get the SDRAM to work on it, but only if I first run it with only EDO SIMMs installed I can get into the CMOS. Erasing the CMOS or holding down the Ctrl key during boot don't help, and I can't boot with the BIOS defaults. My worry is, what if the CMOS is erased one day, and I don't have SIMMs to boot the computer?

The wierd thing is, with my VA-503+ (also VIA chip set) has the opposite problem - I can't get EDO SIMMs to work in it unless I first set the CMOS with SDRAM installed.
 
I have a FIC VA-503+ and I had EDO SIMMS in it for a long time until I upgraded the memory on my main computer and put the old PC100 from that into the FIC. They both booted fine with any change in the CMOS. Are you changing the jumper settings to reflect the change in memory according to your manual? I know that's probably a stupid question, but I had to ask.
 
I tried all sorts of BIOS settings, even the defaults, and I also set the memory bus speed to 66 MHz (even tried PC100 settings, just in case).

This and the problems I'm having getting a PCI TNT2 card to work in the thing make me want to give up on FIC and VIA chip sets in the future.
