I wonder if / suspect this is like the "memory remap" option on my P5B-E... with it DISABLED WinXP sees about 3GB of the 4GB installed but my Ubuntu 64bit boot (Dual boot setup) also only sees about 3GB. With it enabled WinXP only sees 2GB but the 64b OS sees the full 4GB. Something to do with the address it maps to the memory above X. In my case X seems to be 2GB. With it disabled it maps the memory continuous from low address up. Maybe on your mobo X=4GB so you could leave it off (continuous) if you have 4GB or less or a 32bit OS. If you have over 4GB and a 64bit OS then you may want to enable it.

Guessing CONTINUOUS = my DISABLED and DISCRETE = my ENABLED

I suspect with 4GB or less you'll see no difference no matter the OS but should probably use CONTINUOUS in that case.

This is just guess work based on my figuring out the P5B-E memory remap option.

AW can confirm or declare this as 'all BS' when he gets time.

Hi,

I have 4GB installed running on the full 400Mhz on my ASUS A8R32-MVP Deluxe. But when I installed the memory I had 2.8GB, so I tried Memory hole remapping, I reboot, system hanged,...

Then I did some reading and I nodest, I need to set MTRR MAPPING to discrete, now I see the full 4GB's in Vista x64 and XP x64. But when you install 4x1GB the bios sets it to 333Mhz, you can change it manualy to 400Mhz if you have a rivision E4 of E6 CPU, I have a Athlon 64 x2 4600+ rev. E4.

You can find more info on 4GB memory on the buttom of this link: gathering.tweakers.net/forum/list_messages/562830//

regards
Matic

Howdy, guys.

I have 4 pages of new BIOS Options, so I'm attaching them as PDF. I have a good idea what they all do, I'm just submitting them as suggestions to add to the BOG.

MB: ASUS M3N72-D
BIOS: Phoenix-Award ACPI BIOS Rev 0404 08/22/2008
Chipset: Nvidia nForce 750a

I have Dell Inspiron 9400

I reinstalled xp pro went to Dell to get the latest drivers

came across the Intel Matrix storage mgr. got about 3/4

install get a message that computer does not meet

min.requirements will exit install .I get same message when I

tried the video driver. Intel support sent e-mail stating.For mgr

to install. Serial ATA Controller on your laptop must be set to

AHCI or RAID mode. I'm lost. Any help would be appreciated.

Hi ljwalsh,

First of all, this is the WRONG place to post your question. This thread is only to report new or uncovered BIOS options. In the future, please start a new thread.

In any case, your solution is simple - you need to boot into your BIOS (usually using Delete or F2 button at startup) and set Serial ATA Controllre to AHCI or RAID. For more details, read this - Tech ARP - Serial ATA Controller
