2.2.8 Compact Flash Connector
GEME’s standard CompactFlash (CF) socket has an ATA interface that is fully
compatible with an IDE HDD and supports both type-I and type-II CF cards. The
CF socket is on the Secondary IDE port.
2.2.9 Parallel Port connector
Parallel I/O interface signals are routed to a DB25 socket on the front panel. This
port supports full IEEE-1284 capability and provides a basic printer interface that
supports EPP and ECP enhanced port modes
IRQ and Address Setting
The IRQ, I/O address range and mode are all assigned by BIOS.
The following table outlines the parallel port default settings:
