[asxzy]

Hi, I need change my HD4000 graphic card's shared memory on my laptop - Acer V5-471. To do so, the BIOS advanced option need to be unlocked.
Is there anybody to help me with it? Some useful link would help, too.

Thx.

Since nobody would help, which is pretty sad, I dig lots of posts and articles and manage to mod this BIOS by myself. Basically, this Bios shares the same structure with V5-471PG, V5-471G, even other V5 series like V5-571.
The work is still under progressing and I am not sure if I can get it done. Here I changed this topic into a discuss topic and kindly ask for some help. Hope there would be someone would come and work it out.

Here is what I have got now.

Accroding to (UEFI) Dell XPS 15/15z L502x/L511z BIOS MOD HOWTO

1.This is a Phoenix SecureCore Tiano BIOS, same structure with Dell UEFI Bios but not exactly the same.
2.Bios can be extracted with phoenixtool V2.14.
3.There is a "EFI IFR SUPPRESS IF" code in the PlatformHiiAdvancedDxe.efi(CFEF94C4-***.efi) and SystemSetupMainDxe.efi(76016A54-***.efi). But all the pattern 0A 82 45 8A (**) is set as 0A 82 45 8A (01) already. So basically, the advanced menu is not suppressed, at least not in this part.
I tried to find this pattern in all the files extracted from Bios and did not find any luck.
4.Native speed steep can be enabled in PowerManagement2.efi (F7731B4C-***.efi)
Change (75) 08 0F BA E8 0F to (EB) 08 0F BA E8 0F (to enable native speed steep)

What is next
Find out where Acer blocked the advanced Menu.

Other options
1.Access Bios options through EFI shell, provied by [HOWTO] access you BIOS settings through EFI shell.
This is a way to access options in Insyde. However, I could not find the map for my Bios and the EFIshell not working on my laptop.
2.Unlock the Video Memory statement.
Since I only require to mod the video memory which showed in Main Menu, and the block looks like a Locked selector. According to the define of EFI_IFR_LOCKED, we may try to disable this statement and access the selector. However, i am not able to find the hex pattern of this part. I would be appreciated if anyone would verify this idea or help me find this pattern.

Sorry about my English

If there is anyone would like to take part in this Bios, please let me know.

I have tried a lot of things but I am unable to update the bios to a newer version.
I have a weird bug that let's my V5-471g boot up after a shutdown action, it happens after about 8 seconds of being off.

Thought it might be a Linux issue, but it also happens in Windows and I am unable to update bios 1.22 to any 2.x version.

It is a phoenix bios, so the regular insyde bios tricks do not apply.
This issue might be caused by my replacement screen somehow, I have no clue why else it would happen.

If anyone has a 1.22 bios with unlocked options or a working v2 bios, I am happy .

Hi, I'm really new at this, but I would like to request an unlocking of the V5-471G v2.18
Here's a link to the BIOS image:
http://www.mediafire.com/download/z7x76n...8/BIOS.cap

I've been searching for an unlocked version of this for days, but to no avail.
As a last resort, I've made an account for the sole purpose of asking for one since I don't think it exists yet. Or at least, those who have it, haven't shared it on the net.

I just need to access the advanced settings of the BIOS and change the USB wake setting. That's all I really need right now.

If anyone could provide me the BIOS, I would be forever indebted to you.
Please help.

Hello bien112793 and welcome to bios-mods,

This BIOS is Insyde UEFI. I am going to move this thread to the Insyde BIOS Unlocking Requests forum so that it can get more attention from Insyde BIOS modders.

Hi there. May I request for an Unlocked BIOS for Acer Aspire V5-471? I'm running on the latest V1.22 Phoenix BIOS. Here's the link for the BIOS File.

also, there's a V2 BIOS for the same laptop. V2 BIOS has UEFI enabled but there's a problem, I cannot flash a V2 BIOS on a V1 laptop! It just throws me an error when I do so. Please update to the same type of BIOS(V1.xx)!. Any idea how to flash a V2 BIOS on my laptop with V1 BIOS? Here's the link for the V2 BIOS.

http://global-download.acer.com/GDFiles/...R&SC=AAP_5

I still don't get it why Acer really need to do this. V1 BIOS for laptops that run Windows 7 or doesn't include an OS and V2 BIOS for the same laptop shipped with Windows 8! It's easy to flash V2 bios on Insyde BIOS but not Phoenix



Thanks in Advance!

Hello MrChezco1995,

I will take a look at the first BIOS image that you linked to to see what can be unlocked.

I am afraid that I will not be able to help you with matters regarding UEFI though, as that is beyond my field of expertise.
