; REBOOT - Allows the user to Cold or Warm Boot the RomWBW System |
|

; Version 1.0 12-October-2024 |
|

;============================================================================== |
|

; |
|
||||
; Author: MartinR (October 2024) |
|
||||
; Based **very heavily** on code by Wayne Warthen (wwarthen@gmail.com) |
|
||||
;______________________________________________________________________________ |
|
||||
; |
|
||||
; Usage: |
|
||||
; REBOOT [/C] [/W] [/?] |
|
||||
; ex: REBOOT Display version and usage |
|
||||
; REBOOT /? Display version and usage |
|
||||
; REBOOT /C Cold boot RomWBW system |
|
||||
; REBOOT /W Warm boot RomWBW system |
|
||||
; |
|
||||
; Operation: |
|
||||
; Cold or warm boots a RomWBW system depending on the user option selected. |
|
||||
; |
|
||||
; This code will only execute on a Z80 CPU (or derivitive) |
|
||||
; |
|
||||
; This source code assembles with TASM V3.2 under Windows-11 using the |
|
||||
; following command line: |
|
||||
; tasm -80 -g3 -l REBOOT.ASM REBOOT.COM |
|
||||
; ie: Z80 CPU; output format 'binary' named .COM (rather than .OBJ) |
|
||||
; and includes a symbol table as part of the listing file. |
