Troubleshooting
To determine the interrupt for bus touchscreen controllers, run the INFO
utility (typically in \TOUCH). See page 108.
To determine the interrupt for a non-serial mouse, check your mouse
documentation. You may also use the DOS DEBUG utility as in the following
example. Keystrokes are in bold.
C:\>debug
-a
2018:0100 mov ax,24
2018:0103 int 33
2018:0105 int 3
2018:0106 [Enter]
-g
AX=0024
DS=2018
2018:0105 CC
-q
C:\>
In this example the CX register is 0105. The last digit, 5, is the IRQ.
The mouse IRQ is important even if you are using NOMOUSE.COM. The
NOMOUSE.COM on the DOS and Windows Driver Disk does not use an
IRQ. Use this version if possible.
If NOMOUSE.COM was created with PATCHMSE, the above procedure can
be used to determine the IRQ.
Try
AUTOEXEC.BAT and CONFIG.SYS. Check for interrupt contention with
other devices. Remove other devices and drivers to see if they may be
contending with the touchscreen controller or drivers.
