[syslinux] Is it possible to boot a CD-Image of a bootable CD (no disk emu) via pxe
Hello Peter, is it possible to boot a CD-Image of a bootable CD (no disk emu) via pxe. I've build up the infrastructure to boot normal floppy images via PXE (under W2K and/or Netware). I have a ISO image of the bootable CD (1 tack TAO eltorinto with an a single boot sect -> bootimage is 2kB, ISO image about 600 MB) I suspect that a combination of MEMDISK and PXELINUX with activated UNDI support will be needed MEMDISK may be the Kernel and the ISO image will be the initial RAMDISK. Do I need a bootsector from the CD and how do I get it (I know the LBA Adress). Do I need other thing. It would be nice if you have a clue how to do. Yours sincerely Peter Leenders E-mail: Peter.Leenders at gecits-eu.com

It's a bigger project than MEMDISK was in the first place. -hpa
