linux系统下dell PowerEdge2650服务器BIOS升级

.

最近买了两条2G的内存，插上后发现系统每条只认到了1G，我一般很少怀疑别人的人品的，所以想到可能是BIOS版本太低。

在dell的网站上转啊转，在一大堆英文中找到了2650的linux版BIOS升级程序。

wget http://ftp.us.dell.com/bios/PE2650_BIOS_LX_A21.BIN

找台机下载后执行一下

chmod +x PE2650_BIOS_LX_A21.BIN

./PE2650_BIOS_LX_A21.BIN

晕，这个程序用到了rpm等redhat特有的东东，在debian上运行不起来，尝试在debian下安装这些东西，结果失败。

没办法，dell的这个程序只支持redhat和windows，其它版本的操作系统跑不了，我也不想硬来，免得罗嗦。

问人借台机先试一下吧，找了台redhat el5的服务器，运行一下：

./PE2650_BIOS_LX_A21.BIN

等了好一阵子，要有耐心，就会出来一个说明文字，纯英文哦，我看不太懂，先把它拷贝存着，然后按q键跳过说明文字，继续安装：

Error while loading shared libraries: libstdc++.so.5:

cannot open shared object file: No such file or directory.

You must install the Linux compatibility libraries.

To install the compatibility libraries, use the following command:

"rpm -ih compat-libstdc++-33-3.2.3-47.3.i386.rpm"

飘错了，libstdc++没装，在google上搜吧，找到一个：

wget ftp://ftp.pbone.net/mirror/www.startcom.org/AS-4.0.0/os/i386/StartCom/RPMS/compat-libstdc++-33-3.2.3-47.3.i386.rpm

rpm -ivh compat-libstdc++-33-3.2.3-47.3.i386.rpm

这个包居然没有其它依赖，顺利安装完成，重新运行吧：

./PE2650_BIOS_LX_A21.BIN

……说明文字……按q跳过

嗯，这正是我想要的结果了。

今晚去升级那台有两条2G内存的机器，初步定的计划是拿一块2650的装有redhat el5的硬盘，插进去开机改好ip，然后远程升级重启。

升级过程还算顺利，从A10版升级到了A21版，但是并没有能解决2G内存的问题。

想不到办法了，只能退回去换4根1G的。
