Re: Creating DOS bootable CD

Most CDRW software has a "bootable CD" function, where it requests an
actual bootable floppy or an IMG file, and uses it to make a bootable
CD. It then boots to an A: prompt, with all the files on the original
floppy.
If the CD is mounted in WIndows, it appears to be empty.

IBM RecordNow (Sonic) and Nero can do this.
Not sure about Roxio EZ-CD Cremator, , since I'll never touch it
again.

-----------------------------------------

I've looked at your page and can honestly say that I have never seen the
problem that you have experienced with any Roxio product. It is quite
likely that roxio replaced a rogue .dll file installed by something else - a
common occurence, though XP is supposed to have overcome this, not always
successfully

Having said that, the current Easy Media Creator, burns multisession disks
in Mode 1 format - a technically invalid format*, though many current drives
happily read them, but many older ones will only read the first session.
Fortunately XPs own burning facility uses the correct format (Mode 2 Form 1)

Having said that, Nero is not imune from problems, and when they first
supported DVDs, insisted on burning data DVDs in the CD filing system
format. This didn't cause too much of a problem because DVD data drives
didn't care - at least they didn't until dual layer disks came along. Many
drives on seeing a CD format dual layer disk decided that they couldn't
possibly be dual layer and wouldn't read them further. Producing a Video
DVD by copying an otherwise valid file structure onto a blank disk produced
a Video DVD that Video DVD players couldn't play, but data DVD drives could.

Personally, I still do not like Nero, because it does not support packet
incremental format writing to non rewriteable disks. Further it does not
support adding subsequent sessions to multisession disks unless the previous
sessions were all written using that copy of Nero and the session format was
saved. Roxio on the other hand will happily import the previous sessions
from the disk.

*This was the intention of the Orange Book specification, but it was
ambiguous on the point and many drive manufacturers interpreted it that
multisession Mode 1 was valid. This is now the defacto standard if not the
intent.
