on Tuesday, March 19, 2013

Update your operating system and related software is important. On the other hand we have already explained why you should not update the drivers for your hardware, even if the players certainly will want to upgrade their graphics card. But what is the best solution when it comes to updates to the BIOS ?

Updates the BIOS does not speed up the your computer, do not add features that will be needed, and could cause even more problems. You should update your BIOS only if the new version contains an update that you need.

BIOS stands for basic input / output system. When you turn on your computer, the BIOS takes control, starting the POST (Power-On Self Test) and then switching management to the boot loader that starts the operating system of your computer. The BIOS is a low-level software that should simply work, without being bothered. The latest computers, instead of the traditional BIOS have the UEFI firmware - a low-level software with a similar role.
Unlike your operating system (located on your hard drive), the BIOS of your computer is placed on a chip in your motherboard.

Production houses, usually release updates to the BIOS of their computers. If you have built yourself your computer, the BIOS update will come from the manufacturer of your motherboard. These updates are made to the BIOS chip, replacing the BIOS software on the computer with a new version.
The BIOS-based computer (or motherboard), so you will need specific BIOS for your computer (or motherboard) to upgrade the BIOS on your computer.

BIOS updates do not involve major improvements of the software nor add new features, security patches or improvements in performance. BIOS updates usually have short change log - can solve a bug with an unknown hardware or add support for a new type of CPU.
If your computer is running properly, you should not upgrade your BIOS. You probably do not realize the difference between the new and the old BIOS. In some cases, you might even find yourself with new bugs in the latest versions of the BIOS, as the BIOS present in your computer has been subjected to a greater amount of test.
Updating the BIOS is not something as simple as installing a new software update. Probably you'll want to upgrade your computer from DOS (yes, DOS - you may need to create a bootable USB with DOS installed and restart the entire environment), because the problems that you may encounter in updating the BIOS are manifold. Each studio has its own specific instructions to update the BIOS.
You will need the BIOS version is fully compatible with your hardware. If you take the BIOS from another hardware - even a slightly different version of the same motherboard - this could cause problems. Tools to update your BIOS usually try to see if the BIOS is suitable for your hardware, but if despite their differences, however you try to update the BIOS, your computer may become unusable.
If your computer shuts down while updating the BIOS, your computer may become unbootable and broken. Computers, ideally, should have a backup BIOS stored in read-only memory, but not all computers have it.

Given that you might not realize the update, you may encounter new bugs and that there could be potential errors in updating the BIOS, you should not want to update your BIOS, unless you are forced. Here are some cases in which you may need:
Bug: If you have any bugs that have been fixed in newer versions of the BIOS for your computer (check the change log of BIOS on the website of the production company), you might be able to fix it by updating your BIOS. A production company may also advise you to update the BIOS, if you call tech support and have problems that have been fixed with updates.
Hardware support: Some production houses of motherboards add support for new CPU and potentially other hardware, with updates BIOS.Se you want to upgrade the CPU of your computer to a new one - which was probably not yet been released when you bought your - you may need to update the BIOS.
Always check the change log of BIOS updates to see if you need an update.
If you have not encountered bugs that have already been solved and you do not need hardware support, do not bother to update. You will not get anything good, if not other problems.
