Here is a patch that will allow you to move the MOUSE port to some
IRQ other than 3/4, and have it work on ISA machines with
Serial mouse..
----- Cut Here -----
FILE C:\MYMOUSE.SYS
VER 1813 891E890181E3000FFEC7
CHA 1813 891E890181E3000FB7xx
; __ change this to IRQ number required
;
; This patch changes the IRQ for a serial mouse
;
; The standard calculation is as follows
;
; Port addresses = 03F8, 02F8, 3220, etc...
;
; use .x.. nibble of port address +1 as IRQ number
;
; the code above is
;
;
; Mov BX,port_address
; AND BX,0h0F00
; INC BH < we are replacing this instruction with
; MOV BH,xx to force a SPECIFIC IRQ number
; For example below to IRQ 5
;
;
; CHA 1813 891E890181E3000FB705
;
;
; Note: this does NOT change the PORT ADDRESS, so these are expected
; at their STANDARD location....(whatever bios say at 40:0)
;
; To apply this patch, copy \OS2\MOUSE.SYS to \MYMOUSE.SYS (or whatever)
; edit the FILE name above to point to MYMOUSE.SYS (if different)
;
; from an OS/2 command prompt type PATCH MOUSE.PAT /A
;
; Edit config.sys, change the DEVICE=\OS2\MOUSE.SYS SERIAL=1
; to DEVICE=\OS2\MYMOUSE.SYS SERIAL=1
;
; REBOOT
