Hello,

Laptop : Acer Aspire 7738G


Trying to install Leopard , and also run leopard in a WM (ubuntu) however don't have the VT to enable.

If you can also patch DSDT table that would be great.

Possible to also get step and auto dim, frequency patches ?
................................
Normal Bios uploaded here.

This is the modified BIOS image with DSDT patched for Acer Aspire 7738G. Compatible with these models:-

AS7738G 7738 7735G

*AS = ASPIRE

UPDATE (7 Jan 2011): Aspire 7738G BIOS_1.13 MOD.rar
- Same unlocked options as R2
- Enhanced Intel SpeedStep Technology (EIST) Unlocked - for enable Dual-IDA using ThrottleStop.
UPDATE (8 Dec 2010): Aspire 7738G BIOSv2.12 VT MOD_R2.rar

NOTES: I have unlocked other menu as well. Please be careful with it. If your computer doesn't boot after changing something in the sub-menu, you will need to disconnect the CMOS/RTC battery to reset CMOS back to default. To do so, you will need to open your notebook casing.

Please make sure your notebook can recover corrupted BIOS with CRISIS disk before flashing BIOS with this modified BIOS image. I will not responsible for any problem. Good luck.

Aspire 7738G BIOSv2.12 MOD VT.rar

However, I don't think your processor support Virtualization. Please check at Intel website.

I will not responsible for failed BIOS flash. Use it at your own risk.

That is the screenshot of the emulated BIOS Setup Menu. If your processor doesn't support VT, the menu will not appear after flashing it to BIOS chip. With the modified BIOS image, if you upgrade the CPU to new CPU with VT, the menu will automatically appear.

Hello,

could you update the second bios link for the acer aspire 6930G, www.mediafire.com/%3Fezfazmyzxcj does not work for me.

[edit] http://www.mediafire.com/?ezfazmyzxcj (? instead of %3F) works.

Does the modded bios give access to the memory settings? Bought the 2x2GB Kingston KHX6400S2ULK2-4G kit (PC2-6400 CL4) to replace the PC2-5300 memory I had in my aspire 6930G. Problem is, the laptop does not boot with the new memory in. It boots when I try one of the old sticks together with a new one, but not with either 1 of the new on its own or the 2 new sticks together...

Cheers guys!

The only thing in there I could see was a setting to lock the system memory frequency to 667, but no timing options.

Now I understand... and thank you for your quick reply, Darkening! Looking at other posts and the 6930G service manual, the laptop will not run with RAM above 667MHz (see page 21), although the PM45 chipset is quite capable of running an FSB of 800MHz for DDR2. The very same service manual even says so on page 18!

The question now is... can this lock be removed?

Cheers,
John

It isn't locked by default. You can lock it to 667 but the rest of the time I think it runs from the SPD on the memory.

EDIT: I believe you should be able to run the DDR2 6400. From another post in this forum:

"If you have a P processor or one that utilizes a 1066MHz FSB (use CPU-Z to confirm) then your notebook chipset supports DDR2-800 (I assume you have DDR2-667 now)."

Hi Darkening,

My laptop CPU is a T6400 with a 800MHz FSB. CPU-Z says RAM is running 5.5.5.15 at a 3:5 ratio. Upgrading to a x9100 CPU (1066MHz FSB) is a plan, but these are still a bit expensive.

And, I got a reply from Kingston:

Please be advised that the memory you have bought is not officially compatible with your laptop. Please see the links below for the memory listed on the Kingston configurator.

These memories only go up to 667mhz so therefore I would urge you to double-check the limits of RAM speed. The CL difference might be problematic also.

Bummer. I can use SPDtool to reduce the memory speed and/or change the CL4 to CL5 and see if the laptop likes it better.

EDIT: Have just modified the SPD info on one of the sticks and it worked! As the Kingson guy said, the CL4 @ 800MHz DDR was too low for this system. Changing it to CL5 seems to have fixed the problem. So yes, Darkening, you were right about the motherboard/bios/chipset supporting 800MHz memory!! Now running @5.4.4.12 instead of 4.4.4.12. Will flash the other stick to run @ 2x2GB and will stress the system to see if it can cope.

Shame these cannot be set in the bios ;-)

Cheers,
John
