If not detected, USB controller legacy mode will be disabled. When this field is set to [Disabled], USB controller legacy mode is disabled 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]. Configuration options: [Disabled] [Enabled]

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 (4x100MHz for the Intel Coppermine processor or 2x100MHz for non-Coppermine processors). It will then automatically take you to the Advanced menu with a popup menu of all the officially possible CPU internal frequencies.
