Ok - i reworked the procedure a bit whil beeing in Oldenburg. flo@split:~/projects/boot$ mkisofs -J -R -V testboot -o iso tftpboot-r4k-ip22.img Total translation table size: 0 Total rockridge attributes bytes: 262 Total directory bytes: 0 Path table size(bytes): 10 Max brk space used 6644 2208 extents written (4 Mb) flo@split:~/projects/boot$ isoinfo -l -R -i iso Directory listing of / dr-xr-xr-x 2 1750 1750 2048 Sep 27 2002 [ 28] . ?--------- 0 1750 1750 2048 Sep 27 2002 [ 28] .. -rwxr-xr-x 1 1750 1750 4414116 Sep 12 2002 [ 31] tftpboot-r4k-ip22.img flo@split:~/projects/boot$ echo $[ 31 * 4 ] 124 flo@split:~/projects/boot$ genisovh-0.1/genisovh iso sashARCS:124,4414116 ip22:124,4414116 The last command adds a "volume header" in the first 512 byte into the iso file. This volume header spans the whole iso filesystem and lists 2 files at identical positions which is the ECOFF tftpboot-r4k-ip22.img. The name sashARCS is coded in the Indys prom for the installer when using your mouse and "Install System Software" and "Local cdrom". Now one needs to write a wrapper for the Indy bootfloppys aka debian-cd to produce bootable cds.
