Hi All,

I'm trying to create a bootable CD ROM and didn't have much luck.  I
can successfully built a bootable floppy (1 or more) by following the
Linux Bootdisk HOWTO.  However, there is no instruction on how to create
a bootable CD.

Since the filesystem for floppy (ext2fs) and CDROM(iso9600) are different,
I can't use the Linux Bootdisk HOWTO as guide.  Hence I don't know how
to set the kernel where to find the rootfs for iso9600 filesystem.  So I
ended up burning a lot of CD, and everytime, the kernel can never find
the rootfs correctly. quite frustrating :)

If anyone out there can help me, please mail all helps to

Thanks in advance.

Not every PC BIOS can boot from a CD. The Phoenix extensions, however,
provide a possibility to create a CD in the "El Torito" format, to emulate
booting from CD as it would be a floppy (you can find the description of the
El Torito format on the Phoenix web site).

Instead of creating the "El Torito" CD *manually*, you can use a newer version
of the mkisofs utility, which has "-b" and "-c" options.
Essentially, you prepare an image of a bootable floppy and place it in
a directory cone intended for "mkisofs" wrap-up. You point it with the
"-b boot_image" option of mkisofs.

In the mkisofs-1.12b4 source tree there is a README.eltorito which tells
more details.
