Configuration options: [Disabled] [Enabled] [Auto]
OS/2 Onboard Memory > 64M [Disabled]

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.
