2.4 I/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.
2.5 INSTALLING 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.
