4. BIOS SETUP

Notes for JumperFree Mode

CPU Upgrade/Reinstallation

To ensure that your system can enter BIOS setup after the processor has been changed

or reinstalled, your system will start up running at a bus speed of 100MHz and a fail-

safe CPU internal frequency (8x100MHz). It will then automatically take you to the

Advanced menu with a popup menu of all the officially possible CPU internal fre-

quencies.

JumperFree Mode

USB Legacy Support [Auto]

This motherboard supports Universal Serial Bus (USB) devices. The default of [Auto]

allows the system to detect a USB device on startup. If detected, USB controller

legacy mode will be enabled. If not detected, USB controller legacy mode will be

disabled. When this field is set to [Disabled], USB controller legacy mode is dis-

abled no matter whether you are using a USB device or not. Configuration options:

[Disabled] [Enabled] [Auto]

OS/2 Onboard Memory > 64M [Disabled]

When using OS/2 operating systems with installed DRAM of greater than 64MB,

you need to set this option to [Enabled]; otherwise, leave this on [Disabled]. Con-

figuration options: [Disabled] [Enabled]
