HP Compaq DC5800: Xeon Support

[kokos76]

Right now i have two processors officially supported by dc5800: Pentium Dual-Core E5300 (2600 MHz / 800 MHz / 2Mb) and Core 2 Duo E7500 (2933 MHz / 1066 MHz / 3Mb). Like the Q9650, these processors have a CPUID 1067A, Family: 6 (06h), Model: 23 (017h), Stepping: 10 (0Ah) but "core stepping" R0.
To create a microcode patch, I have to purchase a Xeon X3363 SLBC3 (CPUID 1067A) and let you know, right?

Right.

I got a processor. After turning on, the computer with it shows a black screen, and after 15 seconds the cooler turns on at full power.

Make current dump of BIOS by Universal BIOS Backup ToolKit 2.0.

OK. Did you modify the socket of your motherboard?

Make photos of your Xeon from bottom and of the socket.

I already cut the plastic tabs in the socket. Didn’t hurt anything.

Install my version of microcode with your Pentium E5300.
