Acer BIOS Modding

Anyone interested in Acer BIOS modding give me a PM.

 

WOW! You know how to create BIOS!?
OMG!
However, BIOS flashing is too dangerous especially playing with non-official 1. >.<
I know you're kind and willing to help. But I am scared and afraid(coward).

 

Does acer encode their bios files?
Also is the BIOS chip removable/replaceable?

 

It would be good to program in higher RAM support ... actually to the level of what the chipset supports.
I guess C2Q support would be of benefit ... but that's more of a physical limitation.

 

There's something with my 9300M GS, probably a BIOS lock, maybe? It doesn't allow me to OC at all..mine's an InSyde BIOS though, and when I download it it shows up as a .exe file.

 

Interesting.
It seems Acer haven't release 8GB RAM support for many of its laptop.
More precisely, Intel haven't fully release 8GB RAM BIOS support for its products. However, I heard some people already got it(8GB ram) because they edited the BIOS.

Question:
Will 8GB of RAM improve the system a lot?

 

I think the thread starter is on about slic modding of bios.

To activate windows, lol.

 

so you did you own mod?

The 9300M GS BIOS is on the GPU ROM editable by Nibitor
No actually a lot of intel board can utilise 8GB

 

Depends really.
Acer is sketchy on BIOS releases at best, plus they don't really include the information on what was included in the new BIOS to begin with.
So for example ... my chipset is PM45 and by it's own physical capability it should be able to support 8GB of RAM (16 possibly, but I think it's debatable).
The old BIOS my laptop came with supported up to 3GB of RAM ... and it wasn't until I decided to upgrade to 4GB that I saw this limitation ... so I upgraded the BIOS and the x64 OS was able to see and use all 4GB of RAM.

As I already said ... Acer has released a BIOS for my laptop (5930G) some time ago which has a PM45 chipset inside for up to 4GB for sure ... however I have no clue if I'd be able to stick 8GB inside (if the BIOS would support it despite the fact the chipset can).
For one thing, we are lacking 4GB RAM sticks for laptops ... well, they ARE in scarcity apparently and quite expensive, so not really worth the price.

As for if 8GB would improve the system a lot ...
For the average user who browses the Internet, does word processing and similar non-intensive tasks ... I would say 4GB would be more than enough and performance-wise you'd experience no difference.

If however you are using multiple programs at once that are RAM intensive (such as 3d Studio Max like myself for creation of 3d Art ... processing heavy images in Photoshop and other types of applications ... perhaps even intensive games) then 8GB would be more along the lines of 'not running out of RAM and risk system slowdown'.
In terms of working with 3d graphics or processing images, the more RAM you've got, the more images you can process, or you can work on larger ones.

Scenes in 3d programs such as Max can take up lots of RAM depending on how heavy the polygon count is and how high textures you're using.

It's not a matter of improving speed and responsiveness of the OS or programs as much as it comes down to the capacity itself.
The more RAM you have, you can run more applications at once of course or work in programs that are RAM intensive with comfort.

2GB RAM would be a minimum recommendation for comfortable use of the latest OS ... 3GB extends the use for games and medium to heavier RAM intensive applications ... 4GB easily allows you more heavier use.
8GB ... like I said ... use of numerous applications at one time or RAM intensive ones.

 

I explred it with NiBiTor..won't budge.

I think, although the 9300M GS has its vBIOS on the chip itself, it's being locked out of overclocking by the system BIOS..

 

Support for 9300M GS has just been added to release version 5.2
Check out http://www.mvktech.net/content/view/4777/143/

 

WOHHHHOAAAA! So that's why I was having this urge to check that out again..I mailed them saying 9300M GS isn't being supported..

Thanks weinter! +rep

 

So, weinter has modify it for you?
OMG!
It works???

 

No I just happened to inform him support was added in the latest version release recently.
Don't worry about no boot.
Nvidia has special boot clock it only revert to the value you modded after booting into Windows.
So if you have a boot disk you can always flash it back to default.

 

So, the nvidia GPU won't be dead if we have the boot disk?
I mean flashing(bad).

 

Of Course if flashing goes bad like you unplug the bootdisk while flashing halfway it is a gonna.
What I mean is if you undervolted too much it will not kill the GPU (it wil still boot) but of course it will crash in Windows

 

Ohhhhh! I see!
So, power is very important during flashing. Thanks for the information.
Actually, I do plan to undervolt 9500M GS, so, I can overclock it more.
But it is very hard to do it T.T and nobody teach me about it. If you don't mind, can you teach me? Maybe a guide with details. Yet, I am not sure that I would do it or not.

 

If it can allow overclocking the cpu, then yes Possible ?

 

It is possible.
However, it seems it is harder too. Previously, Weinter tried to do something about DSDT table to fix the stupid CPU throttle(downclock) issue for AS 6920G.
But, the solution failed.
I don't know about the BIOS modification(to fix the throttle). Maybe Weinter should give it a try.
Lastly, Nvidia Geforce 9500M GS 512MB DDR2 flashing BIOS(undervolt) guide(super detail) please?

 

Actually I did a new DSDT but no one tried and feedback it just disappeared.
Anyway VGA BIOS Mod is simple.
1)Download eVGA Precision.
Run Test Overclock settings.
Stress Test watch for temps and stability.
Record the frequency.
2)Download Nibitor
Tools > Read VGA BIOS > Select Device > Select Adapter
Modify ClockRates or Voltages
3)File Save BIOS
4)Create a DOS boot disk
Download NVFLASH throw the ROM + nvflash into the boot disk
5)Boot from Boot disk run nvflash to flash the VGA BIOS
Reboot

Note:You might want to backup your original BIOS before modifying.

 

Sounds simple. But how to create a DOS boot disk?
I don't really want to modify clockspeed(So, should I skip EVGA Clock test?). I am concern about voltages.
What voltage level should I put? I mean how much should I lower the voltage? 0.1V? 0.2V?
In addition, should I uninstall the driver 1st before flashing?

 

Create a DOS boot disk by using the Bootdisk creation method in this download
If you don't do overclocking you can skip eVGA
A safe voltage lowering level will be 0.05V
Don't need to uninstall the Driver.
Driver initialise in Windows, doesn't control voltage level, BIOS is much lower level, Driver will take Voltage Values from VGA BIOS so there is no need to uninstall.

 

The Boot Disk mean I need a DVD/CD right? or USB flash drive(pendrive)?
Mind gives(links) all the software needed, such as Nibitor, Nvflash and blah blah.
Spoon feed me please. LOL.
0.05V have any different in temperature? Sounds nothing. LOL.

 

0.05 at first to test if it can remain stable.
If you want 0.1 also can.
Boot disk refer to bootable thumbdrive preferably <2GB
OMG I hate spoon feeding.
All @ mvktech go search don't be lazy.

 

Where is NVflash download link? LOL.
Anyway, have you flashed your Nvidia Geforce 9500M GS?
Lastly, thanks!

 

Ok, in brief, what would be the potential benefits of a bios modding ????? 8 gb ram compatibilty ? Is that all ???

 

Nope.
You can also gain overclocking abilities, EIST controlling and memory clock speed adjustment too.

 

I have no point in OCing memory. It's totally useless. Only a cpu overclocking would convince me but i hardly think it's possible since the setfsb programmer said to me the clock generator on my Acer doesn't allow it. Sounds like a physical limitation.

 

Correct
And btw nvflash can be found on techpowerup

 

After I throw everything to the USB flash drive.
Then, I should enter BIOS and make my laptop to boot the USB 1st?

 

I think you have TME mode enabled. I had the same problem. It's easy to fix.
check the thread in my sig about setfsb and clockgen.

I can help you do the mod.

 

Why the hell the Nibitor said Can't start driver: 1275 while I press Tools> Read BIOS > Select Device??

 

Tried running with admin permission? (Right Click)
Need special permission to load driver to read BIOS

 

Same(still can't read). I run it as Administrator(using right click). Moreover, I am the Administrator(logon as) too.

 

What OS are you running on? x86 or x86_64?
GPUZ also dumps video BIOS.
Last resort is to use nvflash on boot thumbdrive to dump Video BIOS.

 

What you mean by that?
I am on Vista Home Premium 64bit.

 

There is a button to dump BIOS in GPUZ,
if it doesn't work
make the bootable thumbdrive from the link I have given.
Put nvflash on it
Boot from it
Run
nvflash /b BIOS.ROM
to save the BIOS to thumbdrive.

 

How to backup my original BIOS?
So, I throw all those Nvflash folder or files into the thumbdrive?
I should set the BIOS to boot USB 1st right?

EDIT:
I don't want to flash it anymore.
It sucks. I try to edit the Voltage in the Nibitor, it only allow me to lower 0.05V for the 3D(Maximal).
2D and Throttle = can't adjust at all.
0.05V =.=! Is like nothing. Changes only appear if undervolt about 0.1V.

 

I think I know why.
Because the voltages have to be descending order.
If you have 3 clocks
3D Clock has to have higher voltage than 2D Clock and 2D Clock has to have higher voltage than Default clock.
So you have to start adjusting the default and the 2D clock by 0.1V first.

 

LOL. Same.
I tried the 2D and the Throttle Clock. Both of them is 1.15V and the minimum all is 1.15V too. While the 3D clock is 1.2V, minimum will be 1.15V only.

EDIT:
About the bootable USB drive.
If I already have a bootable USB flash drive(using command prompt + Windows 7 disc bootsec), should I use the HP Activator stuffs to do it again? Moreover, it is quite confusing about the activator, I read the "read me" and it makes me even more confuse.

 

If that is the case there probably isn't much you can do.

About the boot disk it is different.
What you need is the DOS boot disk.
Windows 7 doesn't load DOS so use it to create a DOS disk

 

So, I need to install the activator and make my thumbdrive become a bootable DOS?

 

Read the README on how to create the boot disk part.

 

Well, I gave up already.
Because 0.05V undervolt doesn't really help.
It only lower 1-2C(I google around).
My GPU doesn't overheat, I just want to have lower VID of the GPU, so, I can have more OC. With my current OC, I only get 75C as max temperature(need along time to get this temperature though). I wish the flashing undervolt GPU can give me 70C as max temperature. However, 0.05V can't do it.

Lastly, thanks for your help.

 

Anyone know if I can use this to enable VT on my 5720? I really need it for Windows 7 XP Mode.

 

Is-it possible to enable raid on 8935g bios? and enable other options?

Thanks.

 

Hello,
Im interested in That bios thing. My Acer aspire 5100 wont boot. Bad flash!!!

Can you help me?

 

Intel VT anyone?

 

hmmm...how about OCing with a modded bios then?

 

Ignore the 3d 2d etc, the one you want to undervolt is the "Extra" bit, is that showing?

I thought you have undervolted etc before by the way you explain stuff in other threads?
