Move the Mouse Port to Some Other IRQ than 3/4

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.  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
 * CHA 1813  891E890181E3000FB705
