問：dell的optiplex 360或者optiplex 380機器，broadcom網(wǎng)卡如何在redhat enterprise linux 5系統(tǒng)下識別和安裝驅(qū)動？

答案如下：
首先看網(wǎng)卡是否已經(jīng)正確連接到計算機，使用的命令是lspci。redhat上使用lspci的輸出：
[root@localhost ~]# lspci

00:01.0 PCI bridge: Intel Corporation Eaglelake PCI Express Root Port (rev 03)

00:02.1 Display controller: Intel Corporation Eaglelake Integrated Graphics Controller (rev 03)

00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01)
00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01)

00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01)

會發(fā)現(xiàn)系統(tǒng)識別不到這個網(wǎng)卡的設(shè)備，需要更新網(wǎng)卡設(shè)備讀取文件，具體是：
用update-pciids 命令先更新一下 系統(tǒng)的pci.ids文件，這個最新的應(yīng)該有人維護的在http://pciids.sourceforge.net/ 可以找得到。
或者像我這樣直接手工更新一下/usr/share/hwdata/pci.ids 文件的內(nèi)容。
把pci.ids文件放到tmp目錄
Redhat上使用命令：cp /tmp/pci.ids /usr/share/hwdata/pci.ids；回車后回復(fù)yes
再次執(zhí)行l(wèi)spci，結(jié)果如下，成功識別。
[root@localhost ~]# cp /tmp/llj/pci.ids /usr/share/hwdata/pci.ids
cp：是否覆蓋“/usr/share/hwdata/pci.ids”? yes
[root@localhost ~]# lspci

網(wǎng)卡成功識別后，使用ifconfig命令看網(wǎng)卡信息，發(fā)現(xiàn)沒有eth0，需要進(jìn)行如下操作：
下載網(wǎng)卡驅(qū)動安裝包：
kernel-2.6.18-92.el5.i686.rpm
kernel-devel-2.6.18-92.el5.i686.rpm
kernel-xen-2.6.18-92.el5.i686.rpm
kernel-xen-devel-2.6.18-92.el5.i686.rpm
tg3-3.122n-1.src.rpm
使用rpm –ivh 命令安裝上面的kernel包
Tg3包安裝步驟如下：
[root@localhost llj]# rpm -ivh tg3-3.122n-1.src.rpm
1:tg3                    ########################################### [100%]
[root@localhost llj]# cd /usr/src/redhat/
[root@localhost redhat]# rpmbuild -bb SPECS/tg3.spec
[root@localhost redhat]# rpm -ivh RPMS/i386/tg3-3.122n-1.i386.rpm
Preparing...                ########################################### [100%]
1:tg3                    ########################################### [100%]
[root@localhost redhat]# modprobe tg3
打開網(wǎng)絡(luò)設(shè)備：[root@linpcl root]#ifconfig eth0 up
使用命令ifconfig查看可看見eth0

到此Dell optiplex 380 broadcom網(wǎng)卡在redhat 5下網(wǎng)卡識別和安裝驅(qū)動完畢。^_^。
