Well, I did all the process under Linux, but I think you can get the general ideia. If you mount the Bering ISO, there is a file named bootdisk.ima (I think this is the name). This is the file used in that El Torito boot. It loads and then loads the contents in the CD.
You have to mount this bootdisk.ima. The Bering CD is ISO9660 and the bootdisk.ima is msdos under Linux. So I used the following lines to mount then: mount -t iso9660 bering.iso CD/ (here you have to copy the contents to another place) cp CD/ CD_work/ cd cd_work/ mkdir tmp/ (you have to create a dir to mout the bootdisk.ima) mount -t msdos bootdisk.ima tmp/ cd tmp/ (here you can modify the syslinux.cfg and change the LEAFCFG to point to the CD.) So, now you can play with the boot process. This way you can remove entirely the floppies of your firewall. After the changes in leaf.cfg (this one can be in the root of the cd or in the bootdisk.ima) and syslinux.cfg, you have to create de iso. Just umout the bootdisk, remove the tmp (this is not critical), umout the cd, and do the following: mkisofs -R -l -r -o to_burn.iso -b bootdisk.ima cd_work/ After this, burn the to_burn.iso and have fun. :) If you have problems, let me know.
