Bios Option: CPU Fast Decode
Options: Enable / Disable
Description: was hoping u could tell me
Motherboard: ASUS A7N266-VM
Chipset: nVidia nForce

BIOS Option : AGP Fast Write
Options : Enabled, Disabled
Description : Enables Fast Write for the AGP port
Motherboard : Asus A7V333
Chipset : VIA KT333

Turning this option on should give a speed increase of up to 10%. It seems that it can give you problems with the PCI bus though (crackled sound while playing games for examples, I had to turn it OFF).

I found this explanation at FiringSquad:

----------------

Fast Writes is another newly exploited feature that allows the chipset to "force" a PCI transfer to the AGP system, thus bypassing AGP memory.

Without fast writes, any information the CPU needs to pass to the AGP master must be placed in AGP memory for the controller to read. Fast writes allows the CPU to bypass this, speeding up the data throughput.

Fast writes does supply a small improvement in performance, but some video cards don't support this feature. The bus logic method used to initiate a fast writes transfer is determined by the AGP bus mode (1X, 2X, or 4X). Fast Write operations can only take place under specific system conditions, and may cause stability problems. In cases where stability is compromised, the AGP card manufacturer should take steps to disable problematic features without harming the cards' performance too greatly.

Here are a few BIOS options I could not find in the Guide; all are for the same system:

Motherboard: Iwill KK266, BIOS ver. Oct.22.2001
Chipset: VIA KT133A

BIOS Option: DRAM Page-Mode
Options: Enabled, Disabled
Description: Unknown; no manual description

BIOS Option: I/O Recovery Time
Options: Enabled, Disabled
Description: Unknown; no manual description

BIOS Option: AGP Fast Write (probably same as ArKay's post)
Options: Enabled, Disabled
Description: Unknown; no manual description

BIOS Option: IDE Prefetch
Options: Enabled, Disabled
Description: Unknown; no manual description

Those are my contributions at this time. The preferred option is relatively obvious in some of these, but it would be nice to know what they mean. This mainboard was fairly popular; I assume there are still many in use, so others could potentially find value in these additions to the Guide.

Thanks guys, will add them to the list! I don't know how I missed some of them. Thanks again for the heads up!

BTW, snide, I/O Recovery Time has been covered in the BIOS Optimization Guide. Check out the 8-bit I/O Recovery Time and 16-bit I/O Recovery Time BIOS options.

I noticed them, but the options for the 8/16-bit options listed in the Guide are numbers, whereas the options for I/O recovery time that I have on this particular mainboard are enabled, disabled only. I don't know how enabled/disabled corresponds to the numbers in the Guide; i.e., would Disabled = NA, and which of the settings does Enabled represent? Of course, does it realistically even matter when ISA cards are quickly becoming irrelevant?

But thanks for the response.

Adrian Wong · 15th Feb 2003, 12:17 AM

Oh... sorry, snide!

Missed that Enabled / Disabled switch! Will try to find out what I can about it.

Hello!

I have found some undocumented options in my old Pentium MMX motherboard. (brand: Concord)
Can anybody give descriptions about what they do and the best settings?
Thanks.

Any help will be appreciated.

I have the same Bios question, only the motherboard is a Soyo KT400 Dragon Ultra Platinum. The Bios is an Award/Pheonix.

Adrian Wong · 18th Feb 2003, 08:11 PM

Hello dadilus,

The new BIOS Optimization Guide Rev. 7.2 covers the VLINK 8X Support option.

StevenV · 21st Feb 2003, 10:19 AM

first off thanks for a great site
i've referred to it and linked so many times
i'm even going to click through on your adds just in case it helps

bios setting: AT Bus Clock
options: 7.16mhz, clk2/2, clk2/3, clk2/4 (default), clk2/5, clk2/6
description: "Select the speed of the AT bus in terms of a fraction of the CPU clock speed, or at the fixed speed of 7.16mhz."
mobo: Iwill xp333r (04/11/'02 Award bios)
chipset: Ali Magik (M1647/M1535D+)

so what is an AT bus?
and why is it better to run 7.16mhz (if it actually is) when oc'n?

my specs:
iwill xp333r rev.2.1
xp1600 @8.5x200
samsung pc3200
radeon 8500
win2k

tia
