2.3.2 Checking Board Addresses
The Peritek VMEbus graphics boards have three address ranges:

Control Registers Jumper programmable

Line Buffer Software Programmable

Before installing the board into your backplane, make sure no other
devices in your computer respond to Peritek's graphics board addresses,
listed in Table 2-1:

The xxxx is a place holder for digits that are processor specific. Some
common values are shown in Table 2-2. Full memory settings are only
used in multiple Peritek board configurations. The y in the line buffer
address is a placeholder for a digit which is processor specific. The table
on the following page gives you values for xxxx and y for some common
CPUs.
Consult Chapter 6 for more information on determining addresses for
boards not shown in the table.
