HARDWARE CONFIGURATION

The FHL-8135 has only one jumper block for the clocking source. All other configuration is done using the configuration options on the reference diskette. The ADF file for the FHL-8135 is @6DBE.ADF.

PC MEMORY WINDOW ADDRESSES

The FHL-8135 supports two 16 KB windows in the PC memory space to access the memory on the board. There are seven possible choices of segment address for each window. The defaults are D000 for Window 0 and D400 for Window 1.

WINDOW 0: C000, C400, C800, CC00, D000, D400, D800
WINDOW 1: C400, C800, CC00, D000, D400, D800, DC00

PC I/O BASE ADDRESS

There are seven possible choices for the base PC I/O address for accessing the FHL-8135 adapter card. The default I/O base address is 300.

I/O ADDR: 300, 320, 340, 360, 380, 3A0, 3E0

PC INTERRUPT REQUEST LEVEL

There are five choices for the PC interrupt request level to be used when the board microcode wants to interrupt the PC. The default interrupt request level is IRQ 3.

IRQ: IRQ2, IRQ3, IRQ4, IRQ5, IRQ7

J1 - MODEM POWER

This jumper selects the source (external or internal) for the synchronous clocking signals.
external clocks: two shunts horizontal on right two pins
internal clocks: two shunts horizontal on left two pins
