Is there a guide that details how to make a boot image that uses hdd emulation so gets around the 1.44mb/2.88mb size restriction?
I have a need to create a bootable disk image that boots dos and runs a dos diag program. The total size of the image will be 12 mb.
I tried creating a bootable iso but it fails as the boot image uses fdd emulation to boot the iso, so eltorito.sys does not work. I'm at a loss how to boot the cd/iso unless fdd emulation is used. If I load the boot image into the iso with no emulation or hdd emulation the cd/iso is not bootable.
I've created on a spare disk a 15mb fat primary partition with my dos boot files, what program do I use to capture its contents (mbr, boot files etc) into a bootable disk image? Winimage? I tried that program but tbh don't know what I'm doing. It is unregistered, so will I not be able to make a valid bootable disk image from the disk I've setup? Is there any alternative program out there? I do have ubuntu and osx installed, can I use dd with an attached external disk to make a valid disk image (thats bootable)? I have not used dd before so if you can help us with the command line that would be great!
Thanks if you can help!
