hi guys I want to end up with a bootable DVD that will automagically start the kickstart script and perform an unattended install. I have read a few things that say that ks.cfg must be in the root of the image. I've read other things that say that isolinux/ is really the root, and so the ks.cfg must be there. Neither work. In my isolinux.cfg, I have: label ks kernel vmlinuz append ks=cdrom:/ks.cfg initrd=initrd.img ramdisk_size=8192 ks.cfg is in isolinux/ as well as the top-level directory. What am I missing? How do I get the booted OS to read and use ks.cfg? also i had added "default ks" in isolinux.cfg file i had used the following command to make the isoimage of ks.cfg i had placed my dump of fedora8 in /bkup/dump3 "mkisofs -o ../cdrom.iso -A 'ISOLINUX' -V 'ISOLINUX' -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table ." also the .treeinfo and .diskinfo both hidden files are present. then i created the isoimage of my dump with the command "mkisofs -o /fedora.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /bkup/dump3." then i burned the iso image "fedora.iso" to a dvd with the help of k3b the dvd is bootable but at boot time when prompt comes i gave the command "linux ks=cdrom:/ks.cfg" but its giving me the error RAMDISK: compressed image found at block 0 crc error VFS:cannot open root device "<null>" or unknown-block (253,0) please appened a coorect "root=" boot option; here are the available partitions: kernel panic - not syncing:VFS:unable to mount root fs on unknown-block(253,0). also my directory tree is as follows drwxr-xr-x 8 root root 4096 2008-09-24 19:24 . drwxr-xr-x 5 root root 4096 2008-09-24 19:02 .. -rw-r--r-- 1 root root 9627648 2008-09-24 19:24 cdrom.iso -rw-rw-r-- 1 root root 109 2007-11-02 20:29 .discinfo -rw-r--r-- 1 root root 2882 2007-11-02 20:26 fedora.css -rw-r--r-- 1 root root 18363 2007-11-02 20:26 GPL drwxrwxr-x 4 root root 4096 2007-11-02 20:26 images drwxrwxr-x 2 root root 4096 2008-09-24 19:23 isolinux -rw-rw-r-- 1 root root 94 2007-11-02 20:29 media.repo drwxrwxr-x 2 root root 122880 2007-11-02 19:51 Packages -rw-r--r-- 1 root root 9680 2007-11-02 20:26 README-BURNING-ISOS-en_US.txt -rw-r--r-- 1 root root 172530 2007-11-02 20:26 RELEASE-NOTES-en_US.html drwxrwxr-x 2 root root 4096 2007-11-02 20:29 repodata drwxr-xr-x 3 root root 73728 2007-11-02 19:55 repoview -rw-r--r-- 1 root root 1910 2007-11-02 20:26 RPM-GPG-KEY -rw-r--r-- 1 root root 1706 2007-11-02 20:26 RPM-GPG-KEY-beta -rw-r--r-- 1 root root 1519 2007-11-02 20:26 RPM-GPG-KEY-fedora -rw-r--r-- 1 root root 1105 2007-11-02 20:26 RPM-GPG-KEY-fedora-rawhide -rw-r--r-- 1 root root 1076 2007-11-02 20:26 RPM-GPG-KEY-fedora-test -rw-r--r-- 1 root root 1232 2007-11-02 20:26 RPM-GPG-KEY-rawhide drwxr-xr-x 2 root root 4096 2007-11-02 20:26 stylesheet-images -r--r--r-- 1 root root 4290 2007-11-02 20:29 TRANS.TBL -rw-rw-r-- 1 root root 430 2007-11-02 20:26 .treeinfo CD ISOLINUX drwxrwxr-x 2 root root 4096 2008-09-24 19:23 . drwxr-xr-x 8 root root 4096 2008-09-24 19:24 .. -r--r--r-- 1 root root 2048 2007-11-02 20:29 boot.cat -rw-rw-r-- 1 root root 292 2007-11-02 20:24 boot.msg -rw-rw-r-- 1 root root 919 2007-11-02 20:24 general.msg -rw-rw-r-- 1 root root 6587351 2007-11-02 20:24 initrd.img -r--r--r-- 1 root root 10932 2008-09-24 19:25 isolinux.bin -rwxr-xr-x 1 root root 1057 2008-09-24 19:23 isolinux.cfg -rw-r--r-- 1 root root 1389 2008-09-24 19:14 ks.cfg -r--r--r-- 1 root root 103260 2007-11-02 20:24 memtest -rw-rw-r-- 1 root root 817 2007-11-02 20:24 options.msg -rw-rw-r-- 1 root root 517 2007-11-02 20:24 param.msg -rw-rw-r-- 1 root root 490 2007-11-02 20:24 rescue.msg -r--r--r-- 1 root root 446917 2007-11-02 20:24 splash.jpg -r--r--r-- 1 root root 117568 2007-11-02 20:24 vesamenu.c32 -rw-r--r-- 1 root root 1978624 2007-11-02 20:24 vmlinuz VI ISOLINUX.CFG default ks prompt 1 timeout 600 display boot.msg F1 boot.msg F2 options.msg F3 general.msg F4 param.msg F5 rescue.msg menu background splash.jpg menu title Welcome to Fedora 8! menu color border 0 #ffffffff #00000000 menu color sel 7 #ffffffff #ff000000 menu color title 0 #ffffffff #00000000 menu color tabmsg 0 #ffffffff #00000000 menu color unsel 0 #ffffffff #00000000 menu color hotsel 0 #ff000000 #ffffffff menu color hotkey 7 #ffffffff #ff000000 label linux menu label ^Install or upgrade an existing system menu default kernel vmlinuz append initrd=initrd.img label text menu label Install or upgrade an existing system (^text mode) kernel vmlinuz append initrd=initrd.img text label rescue menu label ^Rescue installed system kernel vmlinuz append initrd=initrd.img rescue label local menu label Boot from ^local drive localboot 0xffff label memtest86 menu label ^Memory test kernel memtest append - label ks menu label ^Install from kickstart kernel vmlinuz append initrd=initrd.img ks=cdrom:/isolinux/ks.cfg PLZZZZZZ GUYS HELP ME correcting this error.

Make sure the files you have copied have appropriate permissions: chmod u+w isolinux/* Finally, issue the following command to create the ISO image file: mkisofs -o file.iso -b isolinux.bin -c boot.cat -no-emul-boot \ -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/ Note: The above command was split into two lines for printing purposes only. When you execute this command, be sure to type it as a single command, all on the same line. Burn the resulting ISO image (named file.iso and located in <path-to-workspace>) to a CDROM as you normally would. Those first lines were taken from the ,,, How to Make an installation cd rom, from Red Hat Enterprise linux, You didn't say whether or not you issued the chmod command, Looking at the directory permissions , I'm still unsure, ( haven't done the KS file too much and am unsure of how to bring it all together Myself ) Also,,, ( am unsure of this also ) the ramdisk size being specified, I also believe that it is specified elsewhere, in the Mkisofs command " -boot-load-size 4 " so specifying an larger size may produce an conflict , Sorry to say your attempting something I haven't had much experience with myself and ,,, I do wish you luck,,,, If no one here is able to help Perhaps , the Red Hat , of Fedora Forums may be able to Help... P.S. in the chmod, command the u+w is the u=user ( root ) and the w=write ,,The numbers should probably be 777 chmod og=rw /directory ,,,would give read and write permissions to anybody,,,, Not sure of the exact permissions needed here,,, Good luck Huh !!! MSI 845e mb 1 gb ram and a p4 2.4n running fedora 7 xp ,win 2000 advanced server and win 98 SE alot to learn and I know so little !!!!
