Seems like you've got a non-IDE/SATA optical drive (thus COM/LPT/USB/SCSI/IEEE1394 etc) or maybe SATA with AHCI mode enabled, which DOS won't recognise in all situations. You could add the FreeDOS ISO file to a bootCD which has Isolinux as bootloader and then have Isolinux/Memdisk load the ISO to system memory. The DOS boot image inside of the inner ISO would have to have the ELTORITO.SYS driver so it can find the 'in-memory' CD image.
FreeDOS 1.0 has the boot sequence like this: * Isolinux --> Memdisk --> FDBOOT.IMG (virtual A: , stored in memory, writable) --> driver for physical CDROM unit --> rest of FreeDOS CD --> Setup/Live environment Suggested: * Isolinux --> Memdisk --> FDBASECD.ISO --> Isolinux --> Memdisk --> FDBOOT.IMG --> ELTORITO.SYS --> FDBASECD.ISO's contents as FreeDOS CD --> Setup/Live environment Come to think of it, the ELTORITO.SYS driver should simply already have found your booted CD, as it only loads for each non-emulation mode self-starting CD (as Isolinux is). > How can I make a big (6Mb) bootable image to use in the CD? Some larger images do exist, [ http://bootcd.narod.ru/images_e.htm ] has them listed, including a picture as proof: http://bootcd.narod.ru/fd700000_e.htm You'll likely need to prove C/H/S (cilinder/head/sector) details to Isolinux then if using these non-standard sized images. Linux can easily modify such images, for Windows I guess you'll need a program named WinImage (created by Gilles Vollant) > This is the only part of the CD that I can read on *any* machine, I am > using syslinux) Assume you're using Isolinux :) Using syslinux is entirely possible but involves floppy emulation, with the floppy image containing Syslinux. Quite a waste of assigning driveletter A: to it then :) ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
