Inject floppy image in iso/img image

I'm trying to create a bootable MS-DOS iso, using as the bootcode a Windows 98 Startup Floppy Disk. I need to add add files that exceed a normal 700MB disc, so it must be an iso/img file. Now, due to the fact that a floppy is mostly 1.44MB or 2.88MB, I know that I must add the floppy image as the iso's boot code, to be run in emulation mode.

But for the life of me, I cannot find any tool that will do this. WinImage works only on floppy Images, UltraISO injects extracted boot files but does not accept full floppy images.

What is a good appplication that does this? I got the floppy image from here http://www.allbootdi...ownload/98.html

Thank you

It's been a long time since I've done this but I am sure I used UltraISO for the injection.  I had to setup a boot disk for IDE CDROM support to launch DOS so that I could pull an old Symantec Ghost for DOS off the ISO / CDROM portion of the ISO.  We used to use this for images on VMWare and the old Windows Virtual Server.  I don't believe I have any of the old ISO's around any more.  I switched to WinPE and Ghost32/64.

Could it be just as simple as the extension you are choosing for the floppy image?  Rename it to .img????

You posted in a USB forum. Where does a USB fit in with this?

Boot from USB / Boot anywhere?  I was thinking of highlighted part. If I made a mistake, I ask respectfully to move the thread to where it belongs, thanks.

No problem, just wondered if it would be easier to do if you just booted from a USB drive (if possible) instead of making an ISO.

Well, *any* CD or .iso making tool will do that.

MKISOFS will do but if you are scared by the command line   the good IMGBURN will do nicely.

You can use this tool and create a multi-Iso (.img) CD or DVD: http://reboot.pro/fi...543-mkisofsgui/
This is a Mkisofs GUI made by erwan.l: http://reboot.pro/to...351-mkisofsgui/

Only thing you need to do es create your own menu.lst for launching each: *.img, *.iso, *.gz images form the created Multi-Iso burned to a disc.
