We can often see many upgraded BIOS articles published in newspapers and magazines. What is the BIOS? Why should we upgrade the BIOS? What should we do?
BIOS (Basic Input Output System), basic input and output system. A set of programs that are hardened into a computer to provide the lowest level of direct hardware control for the computer. On the motherboard, we can find a larger integrated block with the words "AMI BIOS", which is what we call the BIOS chip.
The computer is constantly evolving, and it needs to be updated, so now teach you how to optimize it:
1. The TYPE and MODE of the port that is not connected to the IDE device in the Standard CMOS Setup are set to None.
2, set the CPU Internal Cache, External Cache to Enabled, open the CPU level one or two cache.
3. Set System Boot Up speed to High. Make the system boot speed to high speed.
4, set the Boot Sequence to C, A:.
5. Set Floopy Drive Seek At Boot to Disable. Make the floppy drive not detected at startup.
6, set the About 1MB Memory Test to Disabled. No more than 1MB of memory is detected at startup.
7, set Boot Up Floppy seek to Disabled. This will allow the floppy drive to be seeked at startup.
8, set Video BIOS Shadow to Enabled. Map the BIOS on the graphics card to the memory to increase the display speed.
9, set System BIOS Shadow to Enabled. Make the system BIOS map memory and improve performance.
10. Set Video BIOS Cacheable to Enable. Map the BIOS on the graphics card to the cache.
11, set the System BIOS Cacheable to Enbaled. Map the motherboard's BIOS to the cache.
12. Set Cache Timing to Fastset.
13. Set the SDRAM CAS Latency Time to 3. Set the delay time of SDRAM. If your memory quality is not very good, setting it to 3 will greatly reduce the crash situation.
14. The BIOS using VIA Apollo Pro series motherboard chip has a “DRAM CLOCK”; change its value to HCLK+33, so your memory will work at the system FSB +33 frequency, if you The CPU is Celeron, the performance improvement of the system will be very obvious. If your memory is not up to expectations, you can set the value of "DRAM CLOCK" to "HOST CLK" or "HOST-33". ; This is because the Apollo Pro family of chips has a unique memory asynchronous technology.
It is also a reminder that there are several kinds of BIOS, but different blos have different options, and some machines do not have it at all, but it can be optimized according to the above method.
