BIOS Settings Question

[Nailzaz]

Hello Forum

There are 4 settings in my BIOS that I'm not sure what to set at and hopefully you guys can help.

They are:

"Limit CPUID MaxVal"
"Virtualization Technology"
"Execute Disable Bit"
"HPET Function"

Here's my system (below) and thanks in advance for any help.

"Limit CPUID MaxVal" Found this on a site: "Please remember to Enable "Limit CPUID MaxVal" setting if you're running WinNT4.0 with newer main boards in P4 CPU structure. It is especially when you're using Prescott CPU with PCA-6187 and AIMB-742."

"Virtualization Technology" Pretty sure this is for certain virtualisation programs such as VMware, disable if you don't run virtual machines

"Execute Disable Bit" Anti-Virus feature

"HPET Function" Dunno, just leave it alone I guess

What IS Limit CPUID MaxVal?????????????????????????????????????????????

[HSK]

^ i think that might have something to do with using newer CPU's with older Operating Systems...not sure though.

[PsychoChimp]

Can't remember off the top of my head , but have a read through a few of the overclocking guides (search!), they should sort you out.

"Limit CPUID MaxVal" <-- operating systems before Windows 2000 don't undestand CPUID values above 3, it's just a method of identifying what CPU your system has, leave disabled.
"Virtualization Technology" <-- Enables VT instruction extensions for hardware paravirtualisation, used by VMware, VirtualPC 2007, KVM, and other virtualisation subsystems. Leave enabled, doesn't generate any overhead.
"Execute Disable Bit" <-- Allows the operating system to mark an area of memory non-executable, like heap & stack space, leave enabled if you have WinXP SP2 or higher to help defend against common stack smashing attacks.
"HPET Function" <-- CPU function that allows more accurate timing/scheduling if used right by the OS, leave enabled for more efficient scheduling if you have Windows 2000 or newer for a slightly more responsive system.

three

edit: no two
edit: no seven

as for bios settings, as per clunk's great guide, it had all these on Abit boards set to disabled for overclocking - have a read in there.

Could do with moar RAM and a larger screen.

[aidanjt]

Much more ram, and Vista x64... Wtf is the point in running a 32bit OS on such a highend 64bit machine?, go easy on the PSU too, I know nvidia is rubbish for PM but it's not *that* bad.

Well I went out and Bought some more ram and a way bigger screen n mounted it on tha walllllllll n borrowed my cuz x64 version of vista ultimate wit service pack 1.

What the **** has this got to do with the initial question? Don't hijack other people's threads!

PS > You need a Nibnob 360+. Increases the slew rate of the power conduction in many of the components for optimised response times and an even more efficient system. High end systems are effectively crippled without one. They ain't cheap, though!

Hello Forum

There are 4 settings in my BIOS that I'm not sure what to set at and hopefully you guys can help.

They are:

"Limit CPUID MaxVal"
"Virtualization Technology"
"Execute Disable Bit"
"HPET Function"

My mobo manual (Gigabyte GA-P35-DS4) says:

"Limit CPUID MaxVal" = Allows you to determine whether to limit CPUID maximum value. Set this item to DISABLED for Windows XP operating system. Set this item to ENABLED for legacy operating systems such as Windows NT4.0. (Default: Disabled).

"Virtualization Technology" = Enables or Disables Intel Virtualization Technology. Virtualization enhanced by Intel Virtualization Technology will allow a platform to run multiple operating systems and applications in independent partitions. With virtualization, one computer system can function as multiple virtual systems. (Default: Enabled).

"Execute Disable Bit" = Enables or Disables Intel Execute Disable Bit function. This function may enhance protection for the computer, reducing exposure to viruses and malicious buffer overflow attacks when working with its supporting software and system. (Default: Enabled).

"HPET Function" = Enables or Disables High Precision Event Timer for Windows Vista operating system. (Default: Enabled).

"HPET Mode" = Allows you to select the HPET mode for your Windows Vista operating system. Select 32-BIT when you install 32-bit Windows Vista. Select 64-BIT mode when you install 64-bit Windows Vista. (Default: 32-bit)
