I'm not understanding your situation, got some more details?
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 -->
* 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).

Some larger images do exist, [ http://bootcd.narod.ru/images_e.htm ] has
them listed, including a picture as proof:
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)

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 :)
