PC IEEE Reference
Installation Guide.
DIP switches at the upper left hand corner of the board.
The PC IEEE board i/o address can be set be set to reside
at any 4 byte boundary within the address space 0200h to
03FFh. The factory set address, 0300H, is set as shown in
Figure 2-1. The DIP switch numbers 2-8 refer to the I/O address
lines A2 - A8 of the computer. Since the PC IEEE card requires
an address space 4 bytes wide, only address lines A2-A8 have
any effect on the cards I/O address. Consequently A0 and A1
are not connected to the address decoder. DIP 1 is a DON’T
CARE switch, always set DIP 1 ON!

If you need to run the board at a different address then set
the dip switches accordingly. In all, the PC IEEE may be set to
one of 128 possible i/o addresses. There are certain address that
it is always good to avoid, these are given in the following table.
