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.
