ARMD Emulation Type from the BIOS Optimization Guide.
     Wed, Jan 20 2016 | 9:01A | BIOS | PermaLink
Posted by: STAFF
"ARMD is actually short for ATAPI Removable Media Device. It refers to devices that use removable media. Examples include the LS-120, Magneto-Optical (MO) and Zip drives. To boot up any operating system from these drives, it is essential for them to emulate a floppy drive or a hard disk drive. "

Posted by: STAFF
"The 2T Command BIOS option allows you to select the delay between the assertion of the Chip Select signal till the time the memory controller starts sending commands to the memory bank. The lower the value, the sooner the memory controller can send commands out to the activated memory bank."

BIOS Option Of The Week - Rx6C OverWrite.
     Sun, Nov 22 2015 | 4:02P | BIOS | PermaLink
Posted by: STAFF
"The Rx6C register is 8-bits wide and therefore can handle up to eight SDRAM settings. Of course, the number and nature of the SDRAM settings controlled by this register vary from chipset to chipset. This BIOS feature only functions as a switch that determines if the BIOS is allowed to overwrite the default settings of the SDRAM Control register. A separate BIOS feature called OverWrite Rx6C is used to..."

BIOS Option Of The Week - S2K Strobe P Control.
     Sun, Nov 15 2015 | 9:01A | BIOS | PermaLink
Posted by: STAFF
"This BIOS feature determines the P transistor drive strength of the S2K bus. It is used in conjunction with S2K Bus Driving Strength and S2K Strobe P Control to bypass the motherboard chipset's dynamic compensation for the S2K bus. It is slaved to the Manual option of the S2K Bus Driving Strength feature. Therefore, if you set S2K Bus Driving Strength to Auto..."

Desktop CPU Comparison Guide Rev. 16.4.
     Fri, Sep 25 2015 | 9:00A | BIOS | PermaLink
Posted by: STAFF
There are so many CPU models that it has become quite impossible to keep up with the different models or even remember their specifications. Therefore, we decided to compile this guide to provide an easy reference for those who are interested in comparing the specifications of the various desktop CPUs in the market, as well as those already obsolescent or obsolete. Currently covering 1086 desktop CPUs, this comprehensive comparison will allow you to easily compare up to 19 different specifications for each and every CPU.

Read Preamble Time BIOS setting
     Mon, Sep 07 2015 | 4:03P | BIOS | PermaLink
Posted by: STAFF
"When the memory controller wants to read data from a memory module, it sends a DQS (data strobe) signal to the target module. It takes some time before the target memory module actually fires up the DQS data strobe in return to send the data. During that time, it is possible for signal noise to register on the memory controller's DQS receiver and misinterpreted as actual data, resulting in data corruption. To prevent such an occurrence, the memory controller does not immediately enable its DQS (data strobe) receiver. Instead, it waits for a prescribed period of time before activating the DQS receiver for the memory module's actual DQS signal. This prescribed period of time is known as the Read Preamble..."

L1 Data Cache Context Mode BIOS setting
     Sun, Sep 06 2015 | 4:03P | BIOS | PermaLink
Posted by: STAFF
"In current implementations of the Intel Hyper-Threading Technology, each processor has two logical processors. In operating systems that support Hyper-Threading Technology, the processor behaves as two separate processors. These logical processors not only share the processor's execution engine, they also share its L1 cache. This is where this BIOS feature comes in. This BIOS feature allows you to modify the operating mode of the processor's L1 data cache... "

BIOS Option Of The Week - Differential Current.
     Sun, Sep 06 2015 | 4:02P | BIOS | PermaLink
Posted by: STAFF
"This new clocking method reduces the effect of noise on the voltage swing of the system clocks. This results in better timing margins which can translate into tighter, faster timings or better stability. This BIOS feature allows you to change the amount of differential current produced by the clock driver pairs, effectively changing the voltage swing of the system clocks..."

BIOS Option Of The Week - L3 Cache.
     Tue, Jul 07 2015 | 4:02P | BIOS | PermaLink
Posted by: STAFF
"The Level 3 cache is designed to handle data requests that the Level 1 and Level 2 caches fail to satisfy. Although slower than the Level 2 cache, the Level 3 cache compensates by being much larger in size. While the largest Level 2 cache at this time is only 5 MB, Level 3 caches can be as large as 45 MB! Irrespective of the actual numbers, the larger size of the Level 3 cache allows it to store a lot more data than the Level 2 cache. This gives it a high probability of satisfying cache misses from the Level 2 cache. With three caches working together, the chance of the processor stalling due to..."

BIOS Option Of The Week - AGPCLK
     Thu, Jun 18 2015 | 4:00P | BIOS | PermaLink
Posted by: STAFF
Since 1999, we have been developing the BIOS Optimization Guide, affectionately known as the BOG. From a meagre beginning of a single page, it now covers over 440 BIOS options. As old BOG readers will know, we started offering two editions of the BOG since Revision 8.0 - a simplified edition and the complete edition. Normally, the complete edition is only available to subscribers who help sponsor the development of the guide through a small fee. However, that changes today! From now on, we will post a BIOS option from the complete edition of the BIOS Optimization Guide every weekend."The AGP bus clock speed is referenced from the CPU bus clock speed. However, the AGP bus was only designed to run at 66 MHz while the CPU bus runs anywhere from 66 MHz to 133 MHz. Therefore, a suitable AGP bus to CPU bus clock speed ratio or divider must be selected to ensure that the AGP bus won't run way beyond 66 MHz..."
