CentOS 5.5操作系统本来不支持 Logic MegaRAID SAS 1078驱动，安装UIT ContEx 1800时会找不到小盘安装系统，现特制定支持此raid卡的镜像系统盘，直接在isolinux.cfg中dd=cdrom:/raid驱动.img文件，提示选择设备驱动器，没有达到自动安装的目的，现改变方式来制作镜像盘，总结大致需要二步走，第一步，把驱动导入到initrd.img文件中，第二步，需要编辑ks.cfg的kickstart文件，将驱动文件中的.ko文件导入到/lib/modules/`uname -r`/updates/目录下，，mkinitrd来实现，具体步骤如下：
1、挂载光驱mount /dev/cdrom /mnt
2、创建临时目录mkdir -p /root/iso/CentOS
3、提取需要的RPM包，正常安装好操作系统在/root目录下会有install.log文件，这个就是操作系统安装RPM包的记录，我们从这些记录中，将所需的RPM包从/mnt/CentOS中复制到/root/iso/CentOS里面去#!/bin/bashcd /rootawk ‘/Installing/{print $2}’ install.log | sed ‘s/^[0-9]*://g’ >package.txtDVD=’/mnt/CentOS’ PACKDIR=’/root/package.txt’ NEW_DVD=’/root/iso/CentOS/’ while read LINEdocp ${DVD}/${LINE}*.rpm /${NEW_DVD} || echo “$LINE don’t cp…….”done < package.txtrm -f package.txt
4、把原镜像除了CentOS目录外的文件全部复制至/root/iso目录下rsync -av –exclude=CentOS /mnt/ /root/iso
5、解开initrd.img文件（file /root/iso/isolinux/initrd.img查看是gzip文件）mkdir /tmp/initrdcd /tmp/initrdgzip -dc /root/iso/isolinux/initrd.img | cpio -ivdcd modulesgzip -dc modules.cgz | cpio -ivd
modules子目录中的modules.cgz是经过gzip压缩过的cpio包，将其解开。
6、解压raid卡驱动文件megasr-15.00.0120.2012-1-rhel50-U5-64.img文件（file megasr-15.00.0120.2012-1-rhel50-U5-64.img是dos软盘文件）mkdir /tmp/megasrmount -o loop /root/megasr-15.00.0120.2012-1-rhel50-U5-64.img /mediacp /media/* /tmp/megasrcd /tmp/megasr/gzip -dc modules.cgz | cpio -ivdcp 2.6.18-194.el5/megasr.ko /tmp/initrd/modules/2.6.18-194.el5/x86_64/cat modules.alias >> /tmp/initrd/modules/modules.alias
7、生成新的initrd.img文件就像我们以前所做的，修改了源码包中的内容就势必再次打包恢复，这里我们需要把修改过的内容打包成一个initrd.img文件，不过这里要注意打包时的压缩格式，modules.cgz文件用的是crc格式，而initrd.img文件用的是newc格式，命令参数不要弄错。cd /tmp/initrd/modulesfind 2.6.18-53.el5 | cpio -o -H crc | gzip -9 > modules.cgzrm -rf 2.6.18-53.el5cd ..find . | cpio -o -H newc | gzip -9 > /tmp/initrd.img
8、将打包好的initrd.img文件复制到 /root/iso/isolinux 目录cp /tmp/initrd.img /root/iso/isolinux
9、在/root/iso目录下，并根据自己实际需要修改安装要求编辑ks.cfg文件
