PC/104 Expansion Bus
EPM-15 has limited support of the PC/104 bus. Most PC/104 cards will work, but be sure to
check the requirements of your PC/104 card against the list below.
PC/104
I/O

UPPORT
The following I/O ranges are supported:
100h – 1CFh
1D3h – 1D9h
1DBh – 1DFh
200h – 377h
37Fh – 3AFh
3E0h – 3F5h

S
UPPORT
Memory ranges supported:
C8000h-DBFFFh, 8-bit transfers only
DFBF4h
DFE88h
DFE94
IRQ
S
UPPORT
The following IRQs are available on the PC/104 bus:
IRQ 3, IRQ 4, IRQ 10
Each of the three IRQs must be enabled in CMOS Setup before they can be used on the ISA bus.
Because ISA IRQ sharing is not supported, make sure that any IRQ channel used for an ISA
device is not used elsewhere. For example, if ISA IRQ 4 is enabled, you must use a different IRQ
for COM1.
DMA
S
UPPORT
The current revision of the board does not support PC/104 DMA.
