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

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

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]
