Handling Mismatching Processors

This section lists facts and considerations about how the server handles mismatching processors.

■The BIOS performs a complete POST.

■The BIOS displays a report of any mismatching CPUs, as shown in the following example:

AMIBIOS(C)2003 American Megatrends, Inc.

BIOS Date: 08/10/05 14:51:11 Ver: 08.00.10

CPU : AMD Opteron(tm) Processor 254, Speed : 2.4 GHz

Press F2 to run Setup (CTRL+E on Remote Keyboard)

Press F12 to boot from the network (CTRL+N on Remote Keyboard) Press F8 for BBS POPUP (CTRL+P on Remote Keyboard)

■No SEL or DMI event is recorded.
