We had a previous post on我们以前的职位 how to find the BIOS version of a computer如何找到BIOS版本的计算机 using several methods. In this article we will go a little deeper on this topic. The software that I found very handy for this task is使用几种方法。在本文中，我们会继续深入一点就这一议题。软件，我发现非常方便的完成这个任务是 BIOS Agent BIOS的代理 which is a small 328KB executable. Just click the Get BIOS Info on the lower part of the window to start the detection of BIOS info.这是一个小328KB可执行文件。只要按一下BIOS的信息获取的较低部分的窗口开始检测的BIOS信息。

On my Dell Precision M20, the output of this software is below:在我的戴尔Precision M20的，输出的这个软件是如下：

From here we can see the BIOS type and date which says Phoenix ROM BIOS PLUS Version 1 and with a date of 10/02/05. From here we can see that the BIOS version is already 3 years old. Do we need to upgrade? We can see if we need to by looking at the Dell website for this model:从这里我们可以看到BIOS的类型和日期说，凤凰光盘的BIOS普乐士版本1和日期10/02/05 。从这里我们可以看到， BIOS版本已经是3岁。我们是否需要升级？我们可以看到，如果我们需要看戴尔网站这个模型： http://support.us.dell.com

I see that the available version on Dell’s support website is A06 which is the same as the one on my laptop, so I it looks like I don’t need to update it:我看到版本的戴尔公司的支持网站是A06是一样的人在我的笔记本电脑，所以我好像我并不需要更新：

The process is identical for the other PC vendors. All you need to do is identify the current version on your computer and then going to the vendor’s website to see if they have a newer version.这个过程是相同的，其他的PC厂商。所有您需要做的是确定当前的版本在您的计算机上，然后将供应商的网站，看看他们是否有更新的版本。

You will only need to update your BIOS software if the version from the manufacturer is newer than the one installed in yours. In most cases you don’t need a BIOS upgrade. Also, according to, BIOS manufacturer,您将只需要更新您的BIOS软件的版本，如果从制造商是新的比安装在你的。在大多数情况下你不需要BIOS升级。另外，根据， BIOS制造商， Phoenix Technologies凤凰科技 : ：

“The only reason to get a BIOS upgrade is to add support for a new form of hardware you are adding to your system (such as a new CPU, or larger hard disk) that is not supported by your current BIOS. Most operating systems do not use the BIOS once the operating system is up and running, so you should not upgrade the BIOS in an attempt to fix a software bug unless the system/motherboard manufacturer has identified the BIOS as the cause of the problem.” “唯一的理由获得BIOS升级是将支持一种新形式的硬件您要添加到您的系统（如一个新的CPU ，或更大的硬盘）是不支持您目前的BIOS 。大多数作业系统不能使用的BIOS ，一旦作业系统启动和运行，所以你不应该升级BIOS试图修复软件缺陷，除非系统/主板制造商已确定的BIOS的问题的原因。 “

If in case you need to upgrade your BIOS, the installation is straightforward like an ordinary software. The important thing is to make sure that the power to your computer will not die during the upgrade process because a power failure could cause data corruption to your BIOS. It is advisable to have an uninterrupted power supply (UPS) to your computer during this process.如果万一你需要升级您的BIOS ，安装很简单像一个普通的软件。最重要的是要确保电力到您的电脑不会死在升级过程中，因为电源故障可能导致数据损坏到您的BIOS 。可取的做法是，有一个不间断电源（ UPS ）到您的计算机在此过程中。 You will not be able to turn on your motherboard if this BIOS corruption happens. In some older (ie a decade year old computer) systems, upgrading a BIOS means physically replacing a BIOS chip on the motherboard while newer systems just require an installer.您将无法打开您的主板的BIOS ，如果这个腐败发生。在一些较旧的（即今年10岁的计算机）系统，升级BIOS的方式代替身体的BIOS芯片在主板上，而新系统只需要一个安装程序。

Make sure that you have grounded your hands when handling a new BIOS chip or any electronic parts. Electro-static discharge (ESD) could easily fry them. If you are new to ESD, please read this article from请确认您已经停飞你的手时，处理一个新的BIOS芯片或任何电子零件。静电放电（ ESD ）可以很容易地炒他们。如果你是新的公共服务电子化，请阅读本文由 www.esda.org : ：

Make sure to read the details of the BIOS upgrade. In some cases you will need to install an OS service pack to make it compatible with your computer. This might trigger a chain reaction in your installed programs or drivers so make sure to assess the requirements of the BIOS upgrade before you install.请务必阅读的细节BIOS升级。在某些情况下，您将需要安装一个操作系统服务包，使其符合您的计算机。这可能会引发连锁反应在您的安装程序或驱动程序，以便确保评估的要求在BIOS升级，然后再安装。
