BIOS capacity has a limit Upgrade must be noted

With the recent frequent upgrades of various platform accessories, the BIOS is also constantly updated. Generally speaking, upgrading the BIOS will always have the benefit of increasing the functionality and improving the stability of a class. However, this is not absolute, BIOS upgrade the motherboard function downgraded, and even completely can not be used is also there, what is going on? The small partners hurry to stop just about to upgrade the small hands, with the small to understand it.


First of all, what is inside the BIOS of the motherboard, in fact, it is a small operating system, built-in a variety of basic drivers, such as the processor can understand the “microcode”, control the hard disk, memory, graphics card to work on the basic driver, so that these accessories after the boot, before starting Windows can work. The BIOS upgrade is usually to add drivers for new accessories and upgrade drivers for old ones.


And adding new accessories to the driver, of course, the amount of data becomes larger, which requires BIOS has enough space, now the mainstream BIOS is 16MB, in general is enough, but if the luxury motherboard with a good multi-function, or the need to support a particularly large number of processors, it is difficult to say.


For example, the third generation of Riptide, which is now on fire, continues to remain compatible with older motherboards. This makes the BIOS of these motherboards support more processors, some of which can no longer fit so much microcode. These “burst” BIOS will have to delete some features to make room, such as deleting low-end processors, gorgeous settings interface, and some simply delete the RAID and other less commonly used features.


If you upgrade these BIOS, on the three generations of the sharp dragon partners of course is to save money on the motherboard, beautiful. However, for the A10-9800 class of low-end processors, or a group of RAID partners, the trouble can be big, can not boot or data crash are not run.


So, in the recent frequent upgrades of various platform accessories, BIOS also with frequent updates, I strongly recommend: in the case of stable operation of the system, if you do not add any new hardware, or update the operating system, there is really no need to go after the latest BIOS.
