I have also done it several times, but it can't boot. Including creating a new one and modifying with a floppy image. I found that it all fails because the image size can't be fixed. Finally, I have to find a U disk with a suitable size, first make it into a bootable U disk (ZIP or HDD), then use Nero7's burning rom to make a bootable CD. Then read it with ISO. At this time, the size of the IMG or BIF file is fixed. By the way, can the DOS version of Rising anti-virus software make use of the virus database on the hard disk? Its Linux version can. I have also integrated it into my own multi-boot CD.
