G41M-ES2LosX MAC BIOS

[jeffrey1790]

G41M-ES2L MAC EDITION BIOS f8 (Widescreen) by jeffrey1790

===========================================

 

This is an experimental modified bios for Gigabytes G41M-ES2L motherboard.

If anything happens to your board, I WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGE THAT MAY OCCUR.

 

What Does it include?

 

- Gigabyte Slic2.1 (for windows activation)

- Sleep / Shutdown Fix.

- Loads CPU Power Management properly, however doesnt support Speedstepping yet.

- Splash Screen (Widescreen in this BIOS)

- USB/EHCI Speed Fixes.

- CMOS reset fix.

- HDEF Audio (still need 10.6.2 AppleHDA and LegacyHDA_Alc888b.kext)

 

Instructions

 

- Extract BIOS File to USB. Reboot computer, pressing <end> while booting up. Select Bios file, the computer will automatically reboot. Now you can remove your SleepEnabler, dsdt, and/or OpenHaltRestart/OSXRestart.

 

 

Special Thanks to:

Catri - making the mac edition bios / giving me an idea to create my own.

Ridgeline - writing an amazing guide on how to install mac osx on this machine.

 

G41MES2L osx1.1

Renamed devices to mac specific ones.

Looks cool! What bootloader are you using?

Have you tried it on G41M-ES2L revision 1.0 or 1.1?

Does it loads CPU Power Management without a custom CPU section in DSDT?

Using AsereBLN booter 1.1.9. Should work on any bootloader though. I've only tested this on version 1.0 of this board, and it loads AppleCPUPowerManagement with some minor tweaks in the ACPITBL (nothing processor specific though)

Looks very interesting, I just bought this board, will try it out

edit: I have rev1.1 of this board, so not for now.. Good initiative anyway.

All the Revisions of this board seem to be using the exact same BIOS. So, in theory it shouldnt matter which revision you flash this to.

[pirloui]

Ok, thanks; good to know.

I will try it out someday soon; just got the board running with normal kexts

[Wppley2]

Windows 7 can not start anymore. Give me some help please.

[jeffrey1790]

Windows 7 can not start anymore. Give me some help please.

 

Cannot start? Can you be more specific? BSOD? BlackScreen? Also, it seems Windows 7 is working for me fine.

Can you enter safe mode?

[Wppley2]

i need a original bios file to flash with qflash, cause windows 7 says something about acpi incompatibility, and also dvd installer cant run. I want to back to unmodded bios, but on Gigabyte´s site they have all bios files in .exe.

 

(sorry for my bad english).

 

Thanks.

 

 

Edit: Problem solved. i´ve extracted the unmodded bios .rom file in a lap top of a friend and flash in my mobo and everything is good again. I dont know how to explain what happened, but was something related with acpi.

 

Thanks.

Seems like different revisions of this board support different bios versions: rev 1.0 supports anything from F1 to F8, and revisions 1.1 and 1.3 support from F6 to F8 only. Btw, how do i use this .exe you provided? Tried opening it on WinXP in VMware in order to extract the contents to USB, but the application closes immediately.

[jeffrey1790]

Btw, how do i use this .exe you provided?

 

Not sure what exe youre talking about.

Unzip the zip file > copy G41MES2Losx.F8 to your fat/fat32 drive > boot into QFlash by pressing the <END> key > select the bios file.

Alright, looks like i survived the bios update.

The CPU power management seems to work fine, but there's some strange behavior with my graphics card. I'm using 8400GS with GraphicsEnabler,

for some reason when i remove my DSDT the GraphicsEnabler stops recognizing my 8400GS. What GraphicsEnabler has to do with DSDT? I don't know.

Selecting sleep from the apple menu - the computer restarts, and pressing the sleep shortcut on the keyboard - computer shuts down.

 

Here's my specs:

G41M-ES2L 1.1

Intel E6500

8400GS 512MB

 

10.6.3 Retail with AnVAL bootloader, and the following stuff in Extra: http://www.insanelymac.com/forum/index.php...st&id=73320

Do you have any video card information in your DSDT? Also, sleep appears to be working for me. Again, this is kind of an experimental test, I will be fine tuning it in the future, so hold tight.

[XLR]

No, as far as i know. Perhaps it has something to do with my bootloader because i'm using a beta version at the moment. Btw, the sleep issues i've mentioned are happening only with my DSDT, without DSDT when i select sleep the mouse disappears and nothing happens.

[kocoman]

Are there plans to make the bios directly bootable like in the

Is there a way to change the boot screen image? It's great but looks terribly stretched on my 3X4 screen.

[jeffrey1790]

Is there a way to change the boot screen image? It's great but looks terribly stretched on my 3X4 screen.

 

use the included cbrom32.exe, open cmd and do the following:

 

cbrom32.exe G41MES2L1.1.f8 /acpitbl extract

<press enter again>

cbrom32.exe G41MES2L1.1.f8 /logo extract

<press enter again>

edit the LOGO.BMP, save. now

cbrom32.exe G41MES2L1.1.f8 /logo LOGO.BMP

^^ THAT WILL INSERT YOUR NEW EDITED LOGO

<press enter again>

cbrom32.exe G41MES2L1.1.f8 /acpitbl ACPITBL.BIN

<press enter again>

 

CROSS YOUR FINGERS AND FLASH YOUR BIOS!

does this article also apply to the new G41MT-ES2L (Rev 1.0) F4

its the same motherboard in DDR3 Avatar...

 

I'm successfully using iDeneb 10.5.8 lite working flawlessely on it... wanna try Snow Leopard on it...

[jeffrey1790]

does this article also apply to the new G41MT-ES2L (Rev 1.0) F4

 

No.

[LatinMcG]

Count me in the testing. ill post results in a bit..

edit: im not testing as i have a special bios with slic 2.1 for windex 7..i could try it but i would loose win7

reedit: i just saw slic 2.1 i guess i am flashing afterall

G41m-es2l rev 1.0 galaxy gts250 with 1x dvi 1x hdmi.

 

im trying to get this sabrent pci-g802 card to work. shows up under HUB0 in ioreg.. but no luck yet. its in pci slot 2 as slot 1 is covered by heat sink of vid card.

it shows in bios post page under irq 11 . .then in ioreg under irq 13.

hmmm.

edit: pci bus and ppc drivers dont mix in x86.

Good Man jeffrey1790

I have Gigabyte GA-EP35-DS3R and C2D E8400 working with DSDT.aml.

If you have any plan for other Gigabyte Mobo.

I have a DSDT.aml for helpful

Thanks.

 

DSDT.aml.zip

[LatinMcG]

when flashing change setting in QFlash "keep DMI info= disable" catri's bios flashing steps.!

 

1: USB wake from sleep dont work. i have to press pwrbtn (you changed it prety drasticaly without the right info.. ich10 id ? only EHCi needs modding )

2: Video auto detection not working due to PCI0 UID 1 not 0.

(boot with no dsdt.aml in /Extra and extract dsdt then change (pci0) UID from One to 0x00 then save dsdt and boot with it.. video auto detection works)

 

3: PTS shutdown fix not present. but seems it works but slow shutdown .. 40 secs but works!.. or add this

           And (Local0, 0xFB, Local0)
           Store (Local0, ESMI)

           {
               Sleep (0x64)
           }
       }
   }

also i added my Q8300 cpu _PSS only no _CST info to dsdt and i think its working.. apparently the CST info is fixed in bios.

(idle writing this at 34C thats way better than 43C with cst info in dsdt.)

overall this is off to a good start but i wonder if u can join forces with catri site then send them the finished product to post on their site.

 

By the way i have a G31M-ES2L rev 1 also i would love to mod the F10 bios i have it with slic 2.1 allready

also i added my Q8300 cpu _PSS only no _CST info to dsdt and i think its working.. apparently the CST info is fixed in bios.

(idle writing this at 34C thats way better than 43C with cst info in dsdt.)

overall this is off to a good start but i wonder if u can join forces with catri site then send them the finished product to post on their site.

 

By the way i have a G31M-ES2L rev 1 also i would love to mod the F10 bios i have it with slic 2.1 allready

 

Well.... I was just tinkering around with the BIOS file, to see if I could remove the need for a DSDT.aml. Don't really know too much about the best way to optimize / edit it... If anyone has a DSDT for it, which is ACPI compatible (for windows), I can insert it into the BIOS.

[LatinMcG]

those mods should work but best is to ask catri site for guidance as he has done speedstep and acpi compliant.

main worry i have is usb in windows missing some usbs?

another thing is less neeed to mod the dsdt.. so it installs without dsdt need.. but is complimented by dsdt. and keep windows running. i actualy like this so far.. cause i tried catris on a ep45t-ud3l and had minor issues in the sata ide for dvdr.. wasnt burning. might have been dmi issue tho.

[miko88]

Wich program do you use for patching BIOS with the DSDT?

I'm desperately looking for for a patched bios for a GA-G31M-ES2L rev. 2 but anyone got it.

Thanks.
