SeaBIOS seems to be a possibility for the ancient ISA bus machine reactivation project I have begun.  What's currently in ROM lacks INT 13H extension support and is not Y2K compliant.  When last used in the early 2000s, entering a 2nnn year seemed to be OK.  An EEPROM is not present and any "load" would have to burned into 1 or more EPROMs.

TIA, for any replies.
