; 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.

;  FFD0 - FFFF	 48 Bytes	ZCPR3 External Stack
;  FF00 - FFCF	208 Bytes	Multiple Command Line Buffer
;  FE00 - FEFF	256 Bytes	Environment Descriptor
;				Bytes 00H-7FH:  Z3 Parameters
;				Bytes 80H-FFH:  Z3 TCAP
;  FDFF		  1 Byte	Wheel byte

;  E900 - EBFF	.75 KBytes	Resident User Space

; The remainder is for the Operating System.  Exact sizes vary depending
; primarily on the Number and sizes of Hard Drive Partitions, but may be:

;  D100 - EBFF	5.0 KBytes	B/P BIOS (unbanked version)
;  C300 - D0FF	3.5 KBytes	ZSDOS 1.0 BDOS
;  BB00 - C2FF	  2 KBytes	ZCPR 3.3 Command Processor
