Board Status/Error Register Jumpers - Intel SYSTEM 310 Configuration Manual

System 310
056 Board Jumpers
In order to read this register with a software I/O command, you must
first give it an address. Usually, the status/error register resides at
OOOOOH. To select this starting address, connect four pairs of
jumpers: E110 to Elll, E110 to E112, E110 to E113, and E110 to
El 14. Figure 4-4 shows the location of these jumpers. Like the
address select jumpers discussed in an earlier section, the bracket in
this figure indicates that jumper E110 is made up of four stake pins,
all electrically connected.
When you have two or more MULTIBUS R M boards, such as a second
056 board or the 012B board, you must relocate the status/error
register on one of them. This manual recommends that you relocate
the 012B board, and it provides instructions for changing the jumpers
(in Chapter 3). Refer to the iSBC 016A/032A/064A/028A/056A RAM
Board Hardware Reference Manual for the jumper changes on this
board.
