I extracted the 1.44MB bootable image from the Win98 CD-ROM just to do complete. In Win98 WINDOWSCOMMANDEBD folder contains the Emergency Boot Disk (without the msdos.sys & ebd.sys files for some reason). So now am trying to build a MS-DOS 7.0 bootable CD & installation - BUT for games, not generic. Okay, I don't need MS-DOS 6.2 anymore since I found out that the best MS-DOS version was in Win98SE. This message was edited by dhruba.bandopa at 2:33:17 I'm not seeing any big deal over booting DOS from a CD since specifically version 6.2 doesn't support FAT32, although there are TSRs out there that can extend functionality to this and long filenames as well, but only DOS 7+ takes advantage of LFN calls to extend its command implementations when they're available, plus it also supports FAT32.
The Puppy Linux multisession live CD does this.
What would be even cooler is some DOS burning software that could save your new data back to the CD in extra sessions, assuming of course your drive supports booting from multisession discs and can burn and read them without a hitch. To boot DOS from a no emulation scenario I imagine you'd have to write or get some boot code that would hook INT 13h and provide emulation services itself. However on some (or many?) systems floppy emulation may not be supported while no emulation is instead.
I think also SpinRite 6 is able to make a bootable ISO with FreeDOS on it, its other option is to write this same data to a floppy disk. With this method the emulated floppy drive on the CD-ROM will appear as A:, the first floppy drive as B:, and the second will be inaccessible until you turn off emulation. I think this is how Win98's setup CD-ROM worked. I haven't actually done this nor do I know anything about EFI yet so I imagine that with a traditional BIOS you would use El Torito floppy emulation to boot (your burning software should accept a disk and/or image with this option) and use that when actually booting DOS from it to setup a RAM drive and initialize a CD-ROM driver to access beyond the emulated floppy.
