由于游戏业务需求，需要在DELL-2950服务器上安装debian系统，预料之外的是竟然debian系统不能识别板载网卡（Broadcom），郁闷，如何解决？
错误日志如下：
[ 2.871916] Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.7.5
[ 3.631838] firmware: requesting bnx2-06-4.0.5.fw
[ 105.599417] bnx2: Can't load firmware file bnx2-06-4.0.5.fw
[ 105.599563] bnx2: probe of 0000:03:00.0 failed with error -2
[ 106.791394] firmware: requesting bnx2-06-4.0.5.fw
[ 203.699607] bnx2: Can't load firmware file bnx2-06-4.0.5.fw
[ 203.699742] bnx2: probe of 0000:05:00.0 failed with error -2
放狗搜索后，发现解决办法大概有2种：
1，下载相对应的驱动到闪盘，进行挂载安装。
2，通过其他网卡进行apt安装。
分析如下：
当然是第二种方法简单，于是找来一块PCI-E网卡，先能上网再说。
两个步骤就搞定了，简单如下：
1，apt-get install firmware-bnx2
2，init 6
重新启动机器后，查看系统启动日志
debian:~# dmesg | grep bnx2

如果没有出现原来的错误，就OK了，，再不放心，接上网线试试，呵呵
