If the second BIOS was not found and initialized there is not much chance it will function :)
The first MSX BIOS (which will be at slot 0-0 due to the way the hardware i have seen is initialized) must find the second MSX BIOS in the standard way, if that BIOS is designed well and let it initialize. So the RAM will be filled in with the correct information or the second BIOS (and e.g. MSX2 upgrade)will not function. I wonder how many MSX-1s are still being used with that MSX2 upgrade? I know of Brasil, never seen one here in the Netherlands. -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html
