Re: Bootable DOS CD? - May I tag another question to this one ?


When you boot with a CD, the CD must normally remain in the drive because that is where the command interpreter is. You can get around this if you create a ramdisk, copy files (including Command.com) to the ramdisk, and use comspec to specify the command interpreter on the ramdisk. I use this so I can swap CDs on PCs with only one CD device. You could also do it if you want to terminate CD boot disk emulation.
