AMI AMI hidden BIOS settings

I have an ASUS F70-Sl notebook with 4gb of RAM, running 64-bit Windows 7.  
The system shows 4.00 GB of RAM but only 3.00 GB usable.

I've done some searching online, and it seems like this is an issue with memory remapping.  There is supposed to be a memory remap feature in the bios, but I can't find it.

There is also a setting "Maximum Memory" under system config/boot/advanced boot options which I've made sure is not selected.

When I entered the BIOS, there are only a few options.  It looks like a lot of the BIOS settings are hidden.  Is there a way to display and modifiy the hidden BIOS settings?

The BIOS is American Megatrends Inc, version 211.  I've spoken to ASUS customer support,but they were no help.

Thanks!

Thanks!
Brandon

You have Duo core, not dual processors. That is not a bios screen shot. Try flashing your BIOS and using the Del key on bootup to access your bios directly. It does not appear as 64bit.

Ok Wolfhere, I've changed removed the number of processor flag of 2.

I've entered the BIOS directly using the F2 key, but it has only very limited options.  

I believe there are menus which are hidden.

First off...
-just because you unhide the settings doesn't mean it will be linked to a working "code" segment.
-unhiding hidden settings is a good way to turn your system into a doorstop.

That being said, you will need at least 3 things:
-a bios file
-a bios flasher for that file
-a bios editor

The last Editor I know of is  AMIBCP V3.37
If you know what you are doing, you can get the MMTool, which has functions to add/delete/change bios modules.

TOOL_8_RC1.RAR has a collection of tools for "bricking" your system, if you are not careful.

If you upgraded to 64-bit from a 32-bit OS then the old max memory setting is still intact.

Read "System Configuration settings may be incorrect"

PCBONEZ, this has been a fresh install of Widnows 7 64-bit.  I've read the artiicle for KB 978610 and have applied it.

Thanks Coral47.  I don't want to trash my system by messing up the bios.  

I'm hoping there is a way to have the built in Bios editor accessed at boot up can show the setting for memory remap and allow me to make the change through it.

Is there a way for the AMI Bios editor built into the system to show the "memory remap" setting?

>> ...editor built into the system to show the "memory remap" setting?

Sorry, no. That isn't an Editor, it's just a place to tweak what ever settings the mobo maker want you to have access to.
If it isn't shown in the BIOS settings, the only way is to edit the bios file, Unhide that setting, and reflash it with the tweaked file.
Usually just Unhiding a setting will not hurt anything. And it is possible that it isn't even a "live" setting (not linked to any code).

Since this is a laptop, how much ram is the onboard video using? It might be using the missing gig.

bdfallonAuthor Commented:
The specs for the ASUS F70-Sl state: NVIDIA® GeForce® 9300M GS 512MB VRAM

The video card has it's own 1/2 a gigabyte of RAM, so it shouldn't be using any of the system RAM.

I'll try to walk through the process tonight.  

Thanks for your help coral47!

Lets go WAY to the beginning:
>> "The system shows 4.00 GB of RAM but only 3.00 GB usable." <<

The fact that "The system shows 4.00 GB of RAM" tells you this isn't a BIOS problem in the first place.

- Given that: No amount of messing with the BIOS is going to change "only 3.00 GB usable."

The problem is with the Windows Operating System, not the BIOS.

PCBONEZ,

There is a BIOS setting called memory remapping which is supposed to affect this.

I've changed all the window settings, and this is the only one I haven't been able to change.

Thanks,
Brandon

hmmm....comes with Vista Ultimate 32bit..... Intel Core 2 Duo T5900 2.2 GHz Mobile Processor ... From Intel:
Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. See http://www.intel.com/info/em64t for more information including details on which processors support Intel® EM64T or consult with your system vendor for more information.

I would look to your chipset and BIOS (flashing). However; because your system came with 32bit, you do not have the correct chipset drivers for the 64bit OS. From the quote above, EM64T is already enabled! PCBONEZ was correct.

Onboard, schmonboard...its a laptop dude. Nice looking one at that, nice hardware. Better lookin and operating (at 32bit) than my Dell D620 :O. If you do flash the bios, better know what you are doing. Including the hidden settings.....Thank you for the Grand Canyon and good luck with the apocalypse.

Hi Wolfhere,

This system shipped with: Genuine Windows Vista® Home Premium 64 bit which you can see on the manufacturer's website.  

Take care.
