BIOS ROMs are actually nowhere to be found on a regular MK5 system. They can be used to change the system configurations on a PCB board
|

by swapping them with the game ROMs u7/u11 locations.

TODO (MK-5 specific):
|
||||
- Fix remaining errors
|
||||
- If all tests passes, this msg is printed on the keyboard serial port:
|
||||
"System Startup Code Entered \n Gos_create could not allocate stack for the new process \n Unrecoverable error occurred. System will now restart"

"System Startup Code Entered \n Gos_create could not allocate stack for the new process \n

Apparently it looks like some sort of protection device ...
