How does the EEPROM flashing work? I have almost completed the setup program for XTIDE Universal BIOS but i'd like to include flashing to it.
It basically writes to the EEPROM as if it was a big SRAM, however, it have to be timed as most EEPROMs require some pauses between each 1 Byte, 32 Byte or 64 Byte write. The flasher does reprogram the system timer in order to get the pauses rigth.
See http://wiki.vintage-computer.com/index.php/XTIDE_project#The_Flasher for more info on the different timings currently supported.
