First off, excellent forum...lots good information here collected by Fernanado and the community.

My only experience with modding bios is adding slic records...so I'm pretty much a newb to this.


I have an ASUS Sabertooth z77 (bios 2104) and want to update the asmedia 106x firmware. After reading around this forum, I have an idea how to do it but I'm unsure where to place the module into the bios.

Observations:
- I ran the UBU tool, no asmedia entry so I assume I have to do it manually with MMTool.



- I've seen examples that mention using CSMCORE to insert the asmedia orom. I've extracted this module and checked it with a hex editor and found no mention of asmedia.

- Using MMTool, I found 2 other entries that mention asmedia:

ASMedia1061 |A05F5C06-1782-48AA-962A-86A0892022B6|00309D60|001252|DRVR|
ASM1061Pei |77B35E10-AC21-4DFB-B094-DDA8878A6521|004EC6C0|000D9E|PEIM|

Now I'm totally confused...where do I place the module? Any advice would be appreciated, I don't want to brick my mb.

Here's the original un-modded bios for reference:

Edit: Ok after a little more reading and investigating I am going to assume that...
- There is no asmedia orom present in this bios. Judging by the available links present in the mmtool, I only see intel vendors.
- I am still confused about the 2 asmedia entries I found....I'm going to write it off as unexplained newbness and assume that they have nothing to do with orom info.
- So the only solution appears to be to insert the orom into the csmcore module with proper vender and device id.

Am I on the right track?

Thank you Fernando for your prompt reply and for clearing things up!
