SD DISK][ PLUS ROM BIOS V1.90N

Applicable product: SD DISK ][ PLUS card

Major Updates

SmartPort support in HDD mode

• Support for selected games that require SmartPort functionality
• Support for HDD images up to 512 MB

The existing ProDOS Block Device interface remains fully supported, so current programs and disk images can be used without any changes.

ROM BIOS V1.90N adds SmartPort and large-capacity HDD support while maintaining compatibility with existing software.

Updating the ROM BIOS requires replacing or reprogramming the ROM chip installed on the card.
