CentOS 5.5操作系統本來不支持 Logic MegaRAID SAS 1078驅動，安裝UIT ContEx 1800時會找不到小盤安裝系統，現特制定支持此raid卡的鏡像系統盤，直接在isolinux.cfg中dd=cdrom:/raid驅動.img文件，提示選擇設備驅動器，沒有達到自動安裝的目的，現改變方式來制作鏡像盤，總結大致需要二步走，第一步，把驅動導入到initrd.img文件中，第二步，需要編輯ks.cfg的kickstart文件，將驅動文件中的.ko文件導入到/lib/modules/`uname -r`/updates/目錄下，mkinitrd來實現，具體步驟如下：
1、掛載光驅
mount /dev/cdrom /mnt
2、創建臨時目錄
mkdir -p /root/iso/CentOS
3、提取需要的RPM包，正常安裝好操作系統在/root目錄下會有install.log文件，這個就是操作系統安裝RPM包的記錄，我們從這些記錄中，將所需的RPM包從/mnt/CentOS中復制到/root/iso/CentOS裡面去
#!/bin/bash
cd /root
awk '/Installing/{print $2}' install.log | sed 's/^[0-9]*://g' >package.txt
DVD='/mnt/CentOS'
PACKDIR='/root/package.txt'
NEW_DVD='/root/iso/CentOS/'
while read LINE
do
cp ${DVD}/${LINE}*.rpm /${NEW_DVD} || echo "$LINE don't cp......."
done < package.txt
rm -f package.txt
4、把原鏡像除了CentOS目錄外的文件全部復制至/root/iso目錄下
rsync -av --exclude=CentOS /mnt/ /root/iso
5、解開initrd.img文件（file /root/iso/isolinux/initrd.img查看是gzip文件）
mkdir /tmp/initrd
cd /tmp/initrd
gzip -dc /root/iso/isolinux/initrd.img | cpio -ivd
cd modules
gzip -dc modules.cgz | cpio -ivd
modules子目錄中的modules.cgz是經過gzip壓縮過的cpio包，將其解開。
6、解壓raid卡驅動文件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軟盤文件）
mkdir /tmp/megasr
mount -o loop /root/megasr-15.00.0120.2012-1-rhel50-U5-64.img /media
cp /media/* /tmp/megasr
cd /tmp/megasr/
gzip -dc modules.cgz | cpio -ivd
cp 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
就像我們以前所做的，修改了源碼包中的內容就勢必再次打包恢復，這裡我們需要把修改過的內容打包成一個initrd.img文件，不過這裡要注意打包時的壓縮格式，modules.cgz文件用的是crc格式，而initrd.img文件用的是newc格式，命令參數不要弄錯。
cd /tmp/initrd/modules
find 2.6.18-53.el5 | cpio -o -H crc | gzip -9 > modules.cgz
rm -rf 2.6.18-53.el5
cd ..
find . | cpio -o -H newc | gzip -9 > /tmp/initrd.img
8、將打包好的initrd.img文件復制到 /root/iso/isolinux 目錄
cp /tmp/initrd.img /root/iso/isolinux
9、在/root/iso目錄下，並根據自己實際需要修改安裝要求編輯ks.cfg文件
