PC I/O Channel Check
The factory default setting (J1-2 to J1-3 connected) for the DCP386i
provides an interrupt line to the PC for parity errors in the shared memory.
This is the I/O Channel Check signal on the PC bus.
A parity error may instead interrupt the local processor at level 0 of the local
82C59. This can be done by placing the jumper in the LCL position (J1-1 to
J1-2 connected). Refer to Figure 2-12 for the factory default jumper settings.
Window Group Select
The DCP386i contains memory that is shared by the host. The host software
can select the size of the window that is shared using Jumper J3. The factory
default setting (J3-1 to J3-2 connected) allows window sizes of 16K, 32K,
64K or 1M. Changing this jumper plug position (J3-2 to J3-3 connected),
allows window sizes of 16K, 64K or 128K. Figure 2-13 shows the Window
Group Select jumper settings.
