Microcode Update Listing

[KachiWachi]

I didn't know where to actually put this so...

I'm looking for a list of microcode updates and what is contained in the actual update.

mu168314.txt
mu168a01.txt
mu168608.txt

Thanks.

[edwin]

Good question. But shouldn't that be .inc files instead of .txt files?

[KachiWachi]

".txt" was what was written in my BIOS update release notes...

[KachiWachi]

I've found out how to read the Microcode revision from the CPU, Platform ID (BIOS), and update.sys.

Everest can show you the CPU and Platform ID (see this Everest Forum thread entitled Incorrect "Microcode Update Revision". It also explains how to read the revisions loaded from update.sys.

Note: Additional reading -> http://www.intel.com/support/processors ... 001670.htm

My question now becomes how do I find out what is available to the system natively in the BIOS...from the "mu" items I initially listed...so I know what CPU's are supported there?

Example info -

CPU is PIII Coppermine 667 MHz, CA2 stepping, CPUID 681h, MC 11h
Platform ID is 04h (Socket 370), MC 10h
Update.sys is 681-4, 10 (CPUID-Platform ID, MC) (XP SP1, XPClient.010817-1148)

PS - Thanks edwin for the link (also mentioned in the Everest article).

By running CBROM, if it's an Award BIOS.

It's an HP 8766C with v2.02 BIOS (Phoenix)...though Everest says it is AWARD v6.0.

The HP download includes a "bios.rom" (256KB), and uses "smflash.exe".

[edwin]

email the bios and I'll disect it to see what it actually is, phoenix or phoenix/award. Award and Phoenix have merged recently.

[KachiWachi]

Sent.

[edwin]

not received, I'll PM you another email address to try.

[edwin]

It's an award bios allright, the Pegasus-U board for which I didn't have a bios string yet.

Code: Select all

I have the 2.01 BIOS...if you want/need it.

[NickS]

@Edwin: That's a bit odd. The cpucode module is shown as larger than in my example and yet has no entries?
I see the source file is called cpucode.exe instead of cpucode.bin - any significance, do you think?

[edwin]

it is weird but you have to remember this is an OEM bios so it might not entirely follow Award rules. I had too little time yet to do some more research with that individual module, I might have to take the bios apart and check cpucode.exe for what it is.

[KachiWachi]

Hey edwin...

Did you ever get a chance to do this?

Thanks.

0. System BIOS 20000h(128.00K)11EACh(71.67K)stn.bin

It is Asus Award BIOS - use Asus CPU-microcodes filetype.
