+ CAUTION: There is danger of explosion if battery is incorrectly
replaced. Replace only with same or equivalent type recommended by
RadiSys. Dispose of used batteries according to manufacturer’s
instructions.
Peripheral Ports
The I/O address and IRQ of the peripheral ports are determined by the CMOS
parameters established by default and modified via BIOS Setup screens. These
include (2) RS-232 Serial Ports, a bidirectional parallel port, and (2) Universal Serial
Bus (USB) ports. The RS-232 ports and the parallel ports, along with the floppy disk
controller, are implemented by the SMC FDC37C665IR Super I/O Chip.
The address map for the Super I/O Chip is shown in Figure 4-4.
