If the ISA module you are installing does not have an ISA CFG ﬁle shipped

with it, and there is not one listed on the library diskette, you can use the

generic ISA conﬁguration ﬁle, "ISA0000.CFG." This ﬁle can be used to specify

the I/O address, IRQ setting, DMA channel, and memory resources used by the

ISA module.

You must conﬁgure the ISA CFG ﬁle to accurately represent the conﬁguration

of the ISA module. Use the "View or edit details" step to do this.

1. Select "View or edit details" from the "Conﬁgure computer" menu.

2. Use the arrow keys to highlight the module feature you need to set. Items

such as addresses are shown.

3. Press

to see a list of resources used by the option. These resources

include items such as IRQ settings. Many resources displayed by the F6

key are informational only and cannot be changed. If a resource can be

changed, it is displayed with a plus (+) or minus (–) symbol. Press the plus

or minus symbol at the top of the keyboard to select the resource used by

the module.

Note

Setting an ISA module feature in the SCU does not set the feature on

the module. You must ensure that the ISA feature in the SCU matches

the physical conﬁguration of the module.
