On-board flash file system
The Phoenix PICO FA flash file system controls the on-board SSDs,
which allows read/write DOS access to the flash/SRAM devices. SSD0
can also use EPROM/OTPROM. For certain types of flash devices, the
flash file system uses “wear leveling” to spread the usage and maximize
the lifetime of these devices.
Octagon BIOS extensions
On-board BIOS extensions allow easy access to digital I/O, serial
EEPROM, LCD bias control, watchdog timer functions, etc.
Interrupt routing: In system and programmable
Software is on-board the PC-510 to change the interrupt routing and
some other features. The software allows more flexible use of inter-
rupts on the PC-510 and outboard systems such as the PC/104 expan-
sion card.

The floppy disk port supports two drives with either 720 KB or 1.44 MB
