#1 Microcode Update of Insyde UEFI BIOSes by FPSUsername 28.08.2018 14:30

This thread is about updating microcode on Insyde UEFI BIOSes. In this case, for the Acer Aspire 5741(G). It has added UEFI support.

I tried updating the microcode using EzH2O v2.1.0.13 but that can only add microcode. UBU can only read the microcodes, so there's no chance of updating it that way.
The phoenixtools application seems rather difficult to understand, read further for more comments and help.

------------------------
For me the CBROM programs aren't working. It hangs after this part:
CBROM198 NEW70X64.fd /nc_cpucode NCPUCODE.BIN
CBROM198 V1.98 [08/27/08] (C)Phoenix Technologies 2001-2008


TLDR;
Latest unlocked bios + UEFI + updated microcode for the Acer Aspire 5741(G) can be found in post #87

Hello,

you are wrong in this thread with your Insyde UEFI BIOS.
Btw. editing an Insyde BIOS files is mostly not easy, because there are made secure to changes.
But maybe there's a way ... it's a "Phoenix" inside. Phoenix Tool v2.73 could read this .fd-file.
And also tell us which processor is in it (CPUID 20652 or 20655 ?). You can find it in the UEFI-BIOS or AIDA64.

Please write further answers/questions in one of this threads here, here or here.
You could create a new thread, if you like.

Best regards, MiMo

P.S.
You could try flashing the DOS version, I've made (most important microcodes 20652, 20655 and 106E5 updated).
!! I give no guarantee/warranty for using/flashing this BIOS file, but I made it with best surposes by using PhoenixTool v2.73 !!

This BIOS v1.23 is ONLY for Acer Aspire 5741G.

Clarification is needed possibly, here is stock 5471 BIOS link (Not 5471G), in case you could not locate MiesMosel - https://global-download.acer.com/GDFiles...er_1.23_A_A.zip
First padding above NVRAM in UEFITool NE is the microcodes.

Okay, to be clear, I use the bios from here: https://www.bios-mods.com/forum/Thread-U...26930#pid126930

I know it's a 5741G bios, but it works fine on the normal version (only difference is that the non G variant doesn't have the nvidia GT 320 GPU).

This bios has already all unlocked tabs (nothing useful there) and UEFI support. As written in that post, Rainer says he updated the vbios and microcodes (at that time).
I have no idea how he did that.

My CPUID is 20655.

Thanks, so we both had right boards/BIOS there

If you are unsure of BIOS edit @MeisMosel let me know and I can edit my way too if you guys want (not using PhoenixTool SLIC app)

What is the direct link to the BIOS from BIOS-Mods that you are using, so I can edit from there (If you guys wanted), is it the meganz link in post #43?

#7 RE: Microcode Update of Insyde UEFI BIOSes by FPSUsername 28.08.2018 18:41

avatar

Yes, the latest modded bios is from post 43.
I'd like to know how to modify it myself. I want to update the microcodes and as I said in post 53, the intel ME firmware as well

#8 RE: Microcode Update of Insyde UEFI BIOSes by Lost_N_BIOS 28.08.2018 18:43

avatar

OK, I will look into editing the microcode and ME and then let you know methods used. Do you have recovery tools in hand in case of bad flash? CH341A flash programmer and SOIC8 text clip jumper type cable? May be best to order now in case you need later, they are cheap $3 + 2.50

Hello,

UEFI Tool NE seams to be older than the UEFI Tool v0.25.1

So I did it in 2 ways:
- with HxD
- with Phoenix Tool v2.73

I only replaced the three important MCs.

regards, MiMo

P.S.
With my DOS download files you could flash only BIOS or BIOS+ME

@Lost_N_BIOS There is a simple recovery method for bad flashes.
1. Empty fat32 usb (under 2GB) with the bios file called NEW70X64.fd (for the aspire 5741)
2. Remove battery
3. Insert USB
4. Press FN + ESC and boot

Edit:
About @MiesMosel's bios, I believe you only updated the official Acer bios, that one doesn't have UEFI support.
(A few posts later the modded bios is mentioned)

#11 RE: Microcode Update of Insyde UEFI BIOSes by Lost_N_BIOS 28.08.2018 18:48

Yes, I only mentioned to show you another way to see the ucodes location in case you were only using MMTool or hex etc.
For this, age of UEFITool does not matter, they are not years apart, and this BIOS is older than either

Simple recovery like that does not always work if bad flash, that is why I asked, you cannot rely on that in all instances.

@FPSUsername

Which BIOS version w/ UEFI support do you prefer -> mod3 or mod6 ?

#13 RE: Microcode Update of Insyde UEFI BIOSes by FPSUsername 28.08.2018 18:59

avatar

I don't know what the difference is between mod3 and mod6, but before Rainer updated the modded bios (post 43), MarcoMjet said to use mod3

#14 RE: Microcode Update of Insyde UEFI BIOSes by MiesMosel 28.08.2018 19:10

avatar

Okay, I took mod3+VB+MC version.



For mod6, Rainer said

Zitat
I have added the 2120 ironlake bios


Could he mean ironlake vbios?
Then I could update this mod6 version, too.

!! I give no guarantee/warranty for using/flashing this BIOS file, but I made it with best surposes by using PhoenixTool v2.73 !!

#15 RE: Microcode Update of Insyde UEFI BIOSes by FPSUsername 28.08.2018 19:13

Okay, I'll see if I can flash it, I usually flashed the modded bios using the recovery mode, but I don't have the original ram to be able to use it. I'll try the DOS mode.
Could you also update the intel ME firmware? I don't know which version you used in the first attachment.

I attached the latest 1.5MB firmware (I think that one is the latest one for the HM55 chipset)

Edit:
Yes, rainer meant the Ironlake vbios.

But I don't know what mod3 and mod6 means.

2nd edit:
I successfully flashed your mod3 bios.
