MS-DOS and UNIX System IPC-1600 Use
Strategy
Native MS-DOS and UNIX System Operation
Requirement:
The host computer must be set up to have base
memory above 512KB (512KB to 640KB) disabled for
the IPC-1600 to use controller memory starting
addresses 080000h or 090000h. Refer to the
customer documentation that came with your
AT&T Work Group System (WGS) for information
on how to disable base memory.
If you plan to use both the native (boot) MS-DOS and the UNIX system
for the operation of the IPC-1600, proceed as follows.
1.
2.
Follow Chapter 3, “UNIX System Device Driver Installation,”
procedures with the following recommendations.
❑
❑
Install the IPC-1600 board(s) using controller memory address
space below 1MB.
Configure multiple IPC-1600 boards to share one Interrupt
ReQuest (IRQ) level and share the same 64-KB controller
memory address space.
After installing hardware (Chapter 4), install MS-DOS software
starting with Step 3 in Chapter 2. Be sure to specify same controller
memory starting address and I/O address(es) that were set when
installing the UNIX system device driver and IPC-1600 hardware.
