Appendix D - System I/O Map
The following table lists the I/O addresses used
by the system. This is all a very standard PC
compatible I/O map. All other I/O locations from
100h through 3FFh are available on the PC/104
expansion bus.
The I/O ranges of 100h – 13Fh and 200h – 26Fh
are excellent choices for PC/104 daughter board
I/O usage. When designing a custom PC/104
daughter board, a User Chip Select is available
on PC/104 Bus pin B19 that decodes the I/O
range 140h – 15Fh. This can make for a simpler
and more cost-effective design.
