; B/P Bios System Z3 Definition File.
|
||
|
||
; This file is adapted from the basic Z3BASE.LIB configuration file used for
|
||
; most ZCPR33 systems. It has added the new definitions for the Resident
|
||
; User Space defined in B/P Bios descriptions.
|
||
;=========================================================================
|
||
;== NOTE: The Starting Address of the User Space marks the lower ==
|
||
;== base of memory and MUST be entered. B/P Bios Utilities use ==
|
||
;== this address to locate many portions of the operating system. ==
|
||
;=========================================================================
|
||
; To change your systems definition, first sketch out the memory map in the
|
||
; comment table, then set the equates to reflect the memory map, doing any
|
||
; required calculations for element sizes and required spaces. As an
|
||
; alternative, just leave this file alone and configure everything with
|
||
; the utilities provided.
