DAPTER

ARD

(PC473C)

If you are installing this adapter in a Plug-and-Play computer, please read Section

4.2.1.2 prior to installing the adapter.

4.2.1.1 I/O Board Configuration

The default selection for the I/O address is 2718H (318H in the 10-address-bit

terms used by most other PC adapter manufacturers).

The Interrupt level and Memory address defaults are set by the software for IRQ 5

and Memory address DC00H.

Only the I/O address is hardware-selected. If you have an I/O conflict with the

default address, reconfigure your adapter for an alternate I/O address. Two

alternate I/O addresses that rarely conflict with other devices are 2508H (108H)—

all switches off—or 2688H (288H)—switches 1, 2, 3 off and 4, 5, 6 on. We highly

recommend that you do not use any address settings in the range 2408H-24F8H

(008H-0F8H).

Figure 4-1. Configured for address 2718.
