I'm trying to make a bootable CD-ROM with MKISOFS
mkisofs  -o /tmp/cd.iso  -b /tmp/boot.img /temp/w2k3sp1/

but it just tells me  
mkisofs: Uh oh, I cant find the boot image '/temp/boot.img' !

Maybe it's a problem with the boot image.  Is their another way I can extract the boot.img from a bottable CD-ROM?

    It's claiming you don't have a file /tmp/boot.img. Did you make that file first?

    Do this exactly
    #mkbootdisk --iso --device bootdisk.iso 2.4.21-4.ELsmp

    2.4.21-4 is assumed as your kernel version.Replace it with your kernel version.
    Now this will make bootdisk.iso at your current working directory.I assumed it as tmp directory
    After this burn the image on the disk
    #cdrecord -v speed=2 dev=0,0,0 -data /tmp/bootdisk.iso

    Best of luck

    I had a boot.img, but I guess I extracted it from another CD the wrong way.  ibu1 looks interesting, but I'm on cygwin where mkbootdisk isn't available, so I can't try it :-/
