Troubleshooting

Keyboard

If your keyboard is not functional, not detected, or there is a keyboard

error on boot-up, check the following:

• Make sure that the keyboard is properly connected to the

KVM-121. Check that the purple coated keyboard cable is securely

plugged into the correct PS/2 keyboard port (purple colored) and

not the PS/2 mouse port (green colored).

• Verify that the keyboard works when plugged into the computer

directly. You will have to shut down your computer ﬁrst to do this.

• Read your motherboard documentation and make sure that

the PS/2 keyboard’s IRQ is enabled. This can be set for most

computers in the BIOS setup.

• Try using a different keyboard.

on boot-up, check the following:

correct PS/2 mouse port (green colored) and not the PS/2

keyboard port (purple colored).

• Verify that the mouse works when plugged into the computer

directly. You will have to shut down your computer ﬁrst to do this.

• Read your motherboard documentation and make sure that the

PS/2 mouse’s IRQ is enabled. This can be set for most computers

in the BIOS setup.

• Try using a different mouse.

• If mouse movement is random when switching between computers,

try shutting down your computer and rebooting.

• Verify that your computers do not have more than one mouse

driver installed (check your conﬁg.sys and autoexec.bat ﬁles for
