Hello. Sorry to bother you all with a BIOS problem ...
I have a large number of old HP DL145 G1 servers with two Opteron 248 each (single core). I want to upgrade the CPU's to Opteron 280 (dualcore).
I have tried to simply install two 280 CPU's and boot up. The BIOS bootup process first seems to work fine detecting the harddrive, USB, management processor, memory etc. Then there is a warning text "Warning: Unknown processor. Please contact your BIOS vendor for appropriate updates". After that it detects the BMC
I already have the last BIOS available from HP (from 21/7 2005) installed.
Would it be possible to tweak coreboot to make these servers work with dualcore CPU's?
Definitely possible. Probably pretty easy. It's very similar to the amd serengeti_cheetah. If you want to support it, you could start by running superiotool to find out what superio you have. If it is the same as serengeti_cheetah there should be very little work required to support it.
The wiki has useful information about superiotool and getting started.
Thanks, Myles
