The option to change the 1MB chip RAM configuration is "unavailable", presumably because I already have 1MB CHIP RAM. Yes, it is the motherboard hack.
Good thought on checking the ROM setting, but "keep current" is an okay choice to not map the ROM. It is the default, as well. I cycled through to "on board" and when I went to save the profile, it said "already saved" meaning no difference was made. Still, I kept "on board" and tried to boot up. Still only 1.4MB FAST. When I turned off the A500 and went back into the expert menu, the setting reverted back to "keep current".
MapROM is OFF
AUX CF is OFF
I also tried toggling options F4 and F5 to no aviail.

The "Keep current" setting is a bit in the way since you'd like to know what setting it's keeping.
Make sure it's set to "On-board", then turn off MapROM and second CF slot.
If that doesn't help, please take a pic of the Expert Menu settings.
