Hi,
I'm trying to create a bootable CD, and so far I have had limited success.
On the first CD I created, isolinux worked, but I think I had a kernel
without the necessary initrd support compiled in, so the boot failed.
Now I can't even re-create that success. At the moment the CD's
I'm burning
(3 so far) do not even show the display file. I used isolinux-debug.bin for
the last one, and the output I saw was:
ISOLINUX 1.74 2002-0601 Copyright (C) 1994-2002 H. Peter Anvin
isolinux: Starting up, DL = 9F
isolinux: Loaded spec packet OK, drive = 9F
isolinux: Loading main image from LBA = 0000278
isolinux: Sectors to load = 0004
isolinux: Disk error 32, drive 9F
Boot failed: press a key to retry.
To create the iso image I am using the command:
mkisofs -o $ISOIMAGE -b isolinux/${BOOTBIN} \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
-boot-info-table $MASTERISO
(where BOOTBIN=isolinux-debug.bin, and the other variable subsitute for
appropiate files/directories).
The isolinux.cfg file contains
display isolinux.dsp
timeout 10
default linux
append load_ramdisk=1 initrd=root.lrp initrd_dyn=tmpfs,,mkdevr amdisk_size=4096
root=/dev/rd/0 boot=/dev/cdrom,iso9660 LRP=etc,log,local,modules
and an ls -l from my isolinux directory gives:
ghc at lovelace:~/projects/lrp/master_iso/isolinux$ ls -l
total 1388
-rw-r--r-- 1 root root 9016 Jun 7 16:16 isolinux-debug.bin
-rw-r--r-- 1 ghc ghc 8548 Jun 7 15:54 isolinux.bin
-rw-r--r-- 1 ghc ghc 191 Jun 7 14:12 isolinux.cfg

-r--r--r-- 1 ghc ghc 827431 Jun 5 16:13 root.lrp
Can anyone tell me what I'm doing wrong? As the observant will have
noticed, my root is a root.lrp. I'm trying to get the LRP running of a CD.
I have patched the kernel with the neccessary dynamic initrd archive support.
Cheers
