Subject: NorthStar's Split BIOS and ZEX
To: northStar-users@simtel20
cc: rbloom@apg-1
For those that have bothered to try to run Rich Conn's ZEX with
the NorthStar CP/M with a split BIOS - it dona work!
Here is a way you can make it work:
;zexmod.asm 1 July 84 rwb2
;
;This will run ONLY on a NorthStar "64k" CP/M system with the Split BIOS
;with the BIOS located at F300 (which is the default implementation.)
;
;Rich Conn's ZEX (and other "clever" programs) will not run under this
;configuration. This little memory patch allows ZEX to run. Once
;installed, it will stay put until a cold boot. It "should" not bother
;any other programs.
;
;In NorthStar's implementation, the BIOS is split away from the rest of the
;CP/M system. (It was moved to the other side of the PROM at E800h.) In
;order that CP/M will "look" continuous, a copy of the BIOS jump table is
;placed at E700h on the bottom side of the PROM and simply duplicates the
;"real" jump table now located at F300h on the top side of the PROM.
;
;This program alters the jump table at E700 so that it points TO
;the jump table at F300 instead of being copy of the table at F300.
;
; -->THIS SHOULD NOT BE LOADED AS A COM FILE<--
; (unless you "like" 58k files)
;
;Load the patch with the following:
;
; A>DDT ZEXMOD.HEX
; NEXT PC
; E733 0000
; -^C
; A>
;
;that's it! Now Zex and QK will run.
