OptiPlex 360 380 760 780 960 Xeon LGA 771 E0 1067A Microcode

Leaving my case aside (with the e5335), wouldn't it be ok for everyone with the 1067a xeons to have the ucode platform 44 ?
shouldn't that cover also 01 and 10 ?

just asking here, I haven't figured out how the platform mask works.

shouldn't that cover also 01 and 10 ?

No, It's bits mask.
01 - platform 0
44 - platform 2 & 6
10 - platform 4
1067a mask 44 - 45 hm CPU for 771 socket.
1067a mask 01 & 10 - 45 hm CPU for 775 socket.

Hello,

Could someone please explain how do I flash modified BIOS for Dell Optiplex 380 on PC that does not have Windows installed?
I was trying to boot from USB drive into DOS but then package won't run.
Original Dell package runs from DOS very well but how do I run this modified one ?

Thanks.

I don't know how use this mod in DOS, but I can create my own mod (for DOS & Windows).

Thanks for reply.

Could you please help me to add a Xeon E54XX microcode into original Dell BIOS for O380 attached?

Version A06 & A07 have the digital signature. I've made mod for version A05.

Thank you.
I've tried your bios and it works but CPU is not very stable under ESXi. And I think some instructions are missing like SSE4. Not sure if it is caused by older Bios or not ?

[DeathBringer]

What is S-spec of your CPU?
Post screenshot of CPU tab of CPU-Z.
And download Coreinfo, run it command line and post results.

Sorry for confusion SSE4.1 is recognized by Linux on Dell. As well as other instructions. I guess instability may be caused by weak cooler (orig CPU was Pentium E5800). New CPU is Xeon E5430 which has 20W higher TDP.

I attach HW dump from Linux.

[DeathBringer]

You have Xeon E5430 stepping C0 with CPUID=10676, package Socket 771 LGA (platform ID = 6h). Native BIOS version A07 has latest microcode (version 60F, 09/29/2010) for it. You don't need any mod.
