INSTALLATION

2.4I/O ADDRESS SPACE REQUIREMENTS

The I/O address space for the E1100 and E2100 Series adapters occupies 20 Hex of the selected I/O base address. For example, if you select 220 Hex, the adapter I/O address range will extend through 23F Hex.

Note that 23F lies within the address space (230 to 240) allotted to the bus mouse. If your system uses a bus mouse, address 220 cannot be used for the adapter because of the address conflict with the bus mouse. Appendix A, Address/Interrupt Tables, lists the I/O addresses of commonly used devices.

2.5INSTALLING A BOOT PROM

The E1100 and E2100 Series adapters have a socket for an optional Boot PROM. The Boot PROM plugs into the empty 28-pin socket shown in Figures 2-1 and 2-2.

By installing a Boot PROM, you can use the adapter to boot up your PC, without a hard drive, onto a network running, for example, the Novell® NetWare network operating system. A Boot PROM address jumper (JP2) must be set before the Boot PROM can be used, however.

CAUTION: Observe all precautions when handling the Boot PROM. Static discharges may damage the Boot PROM.
