TODO:
- The Retro Web MB pic has a Winbond w83877tf Super I/O but neither BIOSes accesses it, is it specific to the (unavailable) ECS P5TX-LA BIOS?
- pf2012: enters service mode no matter what (failed EEPROM? bad data bank?),
fully resets the machine if exited;
- pf2012: cannot be coined in (lockout read? Enters into gameplay if set to free play);
- pf2012: boots in service mode the first time around, needs default EEPROM set;
- pf2012: PC portion returns an EMM386 "WARNING: Unable to set page frame base address"
during boot up, safe to ignore?
- According to manual hold A+B+service button for 10 seconds for entering test mode during initial bootup
sequence. Board and input test menu doesn't seem to have a dedicated test mode switch.
This statement needs verification once we get there;

Notes:
- pf2012: -isa1 svga_et4k if you need PC side logs;
