- 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
