BIOS Setup

BIOS Setup

To enable/disable Legacy USB Support and/or assign an interrupt to the USB
controller, perform the appropriate actions as outlined below:

1. Immediately after the CPU has been powered on or reset, press F2 to enter the

‘Phoenix BIOS Setup Utility’.

2. Using the arrow keys, select the ‘Advanced’ menu.

3. Using the arrow keys, select the ‘Installed OS’ setting. Press + or - on the number

keypad to toggle the setting between ‘Other’, ‘Win 95’ and ‘Win 98/Win2000’.

4. Using the arrow keys, select the ‘Assign Interrupt to USB’ setting. Press + or –

on the number keypad to toggle the setting between ‘Enabled’ and ‘Disabled’.

NOTE:

See “Using USB Keyboard/Mouse with Microsoft Windows Operating

Systems” on page 86 for proper setting.

5. Using the arrow keys, select the ‘Legacy USB Support’ setting. Press the + or -

keys on the number keypad to toggle the setting between ‘Enabled’ and
‘Disabled’.

6. Press
