PC DOS may be far too old for this usage. I would fetch a dos boot disk of more recent vintage from http://www.bootdisk.com and use that as the boot A: source for this CDR.
"And Here's Another Way For You To Make Bootable CD's
To Create A Bootable CD, You Need A CD-Burner, Roxio Easy CD Creator, A Blank CD-R Disk And The Bootable Source Media. (The source can be a floppy diskette, a hard drive or a previously created image file of any of these. Use "Help" if confused at step four below.)
After You Have Gathered Everything Together:
1. Put the blank CD in your drive
2. Start Easy CD Creator
3. Select "File", "New CD Project", "Bootable CD"
4. Select the bootable CD type
5. Then Select "OK"
I'm trying to make a bootable CD using EZ CD Creator 5.3. I followed the instructions: Make a data CD, File - New CD Project - Bootable CD - Use an existing image (which will copy the Bootcat and Bootimg.bin files). I then select another program (SpinRite) and add it to be burned. It creates the CD with the 3 files but when I try to boot from the CD I receive a "starting PC Dos" screen, and it just hangs there. Any ideas?
