HP DC7900 CMT xeon x3363 Bios Mod

[kuzma2000]

Hi! I have a DC7900 with E5300 processor. I want to replace it with Xeon. I can buy x3363 and i have E5450. I have a hardware programmer and I can read and write the firmware. What kind of Xeon I can put on this board? How to modify the BIOS for it?

Make current BIOS dump by a hardware programmer, zip and attach.

Xeon E5450 isn't supported.
I think that BIOS can be modded for X3363.

[kuzma2000]

Yes, now it's clear why the PC didn't work with E5450
Question:
I will order X3363 on e-bay
You wrote that you can try to add X3363 support to Bios. While I wait for Х3363 can I solder flash on the board and use the old processor?
Or I must use only X3363&

[DeathBringer]

Yes, you can solder it back but save the file with BIOS dump.

Do you mean the option of using 786G_ucode? Upgrading microcodes after a successful start PC witch X3363?
Or are you modifying the dump and I'll write it on a flash?

[DeathBringer]

As you wish

I'm sorry, but I don't understand
I don't really want to disassemble the PC again...
If you can change my BIOS dump to add X3363 support, I'm ready to wait.
After that, I'll write new dump on the flash, solder it on the board and will stay waiting for the X3363 which I have already bought.
Or the system will start without modification BIOS dump? I need only use 786G_ucode to add microcodes?

No CPU - no help.
