BIOS (Basic Input / Output System) - is a basic input / output system. More precisely, BIOS is a system configuration and memory management, processor, chipset, on-board controllers, and connected to the motherboard devices. Unlike most other programs, BIOS is not on the hard drive, and a special battery-powered chip on the motherboard. From the BIOS in your computer depends on many things. In fact, BIOS determines the configuration of the system, which defines the functionality and performance PCs. Often the first version of BIOS, which appear motherboards, and full of bugs, disappearing only in later versions.
Configuring AMI BIOS Tool :
One thing you must note down before this. Flashing or modding BIOS can be dangerous which make your pc dead. So you must perform this on your own risk and better go through the post first. The BIOS option suppresses all the more obscure than the others. We'll see how to set a BIOS (the images were made using as a model AMI BIOS).
First you must enter the BIOS. If you read the previous article, you should be in front of a screen of this type when you are in the BIOS Setup. You then have different keyboard keys to more through the BIOS Setup and change its options. In our case we will use the + and -, and the arrow keys. Now what are all the options (or almost) the BIOS. BIOS is located in the ROM-chip memory (Read Only Memory), which provides continuous availability of BIOS, regardless of performance are external to the motherboard components (such as boot drive). Because access to RAM (memory) is much faster than ROM, many manufacturers provide the power automatically copy BIOS from ROM to RAM. Involved during this area of memory called the Shadow ROM.
Currently, most modern motherboards equipped with microchips Flash BIOS, code that can be overwritten using a special program. This approach allows updates (firmware new version) BIOS. Producers kernel BIOS is not so much. The most common BIOS from companies AMI (American Megatrends, Inc.), AWARD and Phoenics Technologies. Other BIOS (from companies FirmWorks, Micro Firmware, etc.) occur much less frequently. And now dominates the market AMI BIOS, so in the future you can focus on ways to re-flashing and modifying it up. Naturally, each manufacturer makes its own changes to the basic version of the BIOS, and, of course, one or another version of BIOS is only intended for a specific product (a PC or laptop) and is inconsistent with other decisions.
The main screen allows you to first change the time and the language used in the BIOS, and the type of your floppy drive (option set to 1.44M, 3.5 In). You then have the ability to configure drives and IDE hard drives. To do this, select using the arrow keys to configure the drive and press the enter key. Leads you to options you can configure your player. Here is an explanation for each of these options:
- Type: Select Auto if you prefer to let the BIOS detect your drive. Otherwise, enter CDROM if your device is a CDROM drive, otherwise put ARMD
- LBA / Large Mode: Enables or disables the LBA mode. If your drive supports this mode (which is usually the case), set Enabled.
- Block: Block Select mode, it can increase the performance of hard drives. If your device generates problems then disable this mode.
- PIO Mode: In case your player does not support DMA mode, select PIO mode. PIO Mode 4 is the one who offers the best performance, however, well below the DMA mode.
- DMA Mode: Select the DMA mode most appropriate for your reader. UDMA Mode 5 is the one that is more efficient.
- SMART: Analyzing if your hard drive will not give up the ghost. If your drive supports this option, click here.
- 32 Bit Data Transfer: Enable 32-bit to get the maximum possible performance.
Once this is completed, select the screen ADVANCED using the arrow direction right. You'll be presented with this screen.This category provides an impressive amount of change of parameters. Be careful, the amendment of certain options may cause the system to restart properly. Start by selecting the category Jumper Free Configuration. You're now in front of the screen.
Here are the options that you can change:
1. AI Overclock Tuner: If you want to give a quick boost to your configuration, this option is for you. But beware, it overclock the processor when it is used heavily in order to
2. Reserve of power. Select the setting "Standard" if you do not want to overclock your processor. You can give different percentages (5-30%). Thirty% is not recommended, you could fry your processor. If you set this parameter to [manual], new options appear allowing you to change the frequency and voltage of the RAM, AGP bus and processor.
3. CPU Ratio: If the multiplier of your CPU is not locked, you can change the ratio (and hence overclock your processor).
Performance Mode: Leave the [self] if you do not know what charge can support the RAM on your system. If you have any good bars, set to [Turbo], otherwise the [standard] . Then go back on the screen ADVANCED menu and select CPU configuration.
4. Configure DRAM Timing By SPD: You can now configure the memory timings. If you do not know what values to place, proceed by trial and error or set this to [Enabled]. SPD (serial presence detect) automatically configures the values. Otherwise set [disabled] to access all options. Then choose the smallest possible values to speed up your PC. If you can not restart or your PC is not stable, increase the values gradually.
5. Memory Acceleration Mode: You can set this value to [Enabled] to speed up your PC. Your RAM sticks must be of good quality. DRAM Idle timer: interval of time before you open or close a section of RAM. Put "0T" for maximum performance.
6. DRAM Refresh Rate: Set the interval time between two refreshments of RAM. A large value can make you lose information, but speeds up the system.
7. Graphic Adapter priority: This option is used to define the display device to be taken into account at startup. If you do not have integrated graphics, PCI, put [AGP / PCI], otherwise [INC / AGP].
8. Graphics aperture size: Quantity of textures can be stored in RAM. Put a value which corresponds to about one quarter of your RAM.
9. Spread Spectrum: This option should normally help to reduce interference. Put this on [disabled] because it can cause problems.
10. ICH delayed transaction: Set this option to [disabled].
11. MPS Revision: Set this option to [1.4].
