ISO文件里加驱动后装系统起不来

city_85

在IBM xserver3550 M3机器上装redhat4.7 64位系统,IBM提供了RAID卡驱动ibm_dd_sraidmr_00.00.04.17_rhel4_32-64.tgz,从里面提取出dud-2.6.9_78-32_64.RHEL4.img文件,拷贝进U盘,这样安装没问题,但是现在我不想用U盘,因为有些条件限制,现在我把dud-2.6.9_78-32_64.RHEL4.img驱动文件放进redhat的ISO文件的isolinux目录里面,并且修改isolinux.cfg文件(红色为新增):

  append initrd=initrd.img lowres ramdisk_size=9216

同时在ISO的images目录下的boot.iso里面同样增加dud-2.6.9_78-32_64.RHEL4.img驱动及修改isolinux.cfg文件,重新编辑ISO,刻录光盘后安装系统,进入安装界面后敲:youshang加载驱动,然后突然就死机不动了:

请问哪里出错了,另外之前修改initrd.img的时候,发现修改pcitable,modules.pcitable,module-info,pci.ids等好难.有没有之类的文章提供的.谢谢!
