Unsupported CPU Detected

[Kenneth_73]

I tried to boot up a ML570 ProLiant server and received the following error:

Compaq System BIOS-P20 (01/21/2001)

Processor 1 Initialized at 900/100 MHZ with 2MB Cache
Processor 2 Initialized at 900/100 MHZ with 2MB Cache
Processor 3 Initialized at 900/100 MHZ with 2MB Cache
Processor 4 Initialized at 900/100 MHZ with 2MB Cache
Unsupported processor detected
system halted.

Can anyone help me solve this problem

Run over reset
Try to downgrade to dual CPU (I believe you will be needed Terminator board instead others CPU)
Invalidate CMOS Settings, use jumper #6 from System Maintenance box (use side panel for legend)
Disconnect any additional Cards
Swap CPU around
See if Error will go away when nothing connected
Verify Latest System ROM

I/O board might be defective

KOV nailed it, you need the ROM at a minimum of 4/15/2001 to support the 900Mhz CPU:

Just upgrade to the latest ROMPAQ and you are rocking.
