If not too late...
To create a bootable MSDOS 6/7 floppy with CD-ROM support you need mscdex.exe (messy decks ... MicroSoftCompactDiscEXtensions).
iirc... in DOS6 and Win9X (not 2000, XP or NT!), you created a bootable floppy by typing
This created a bootable system floppy disk which could boot into DOS, and then to get the CD drive working you had to copy over and start mscdex.exe with the correct arguments from the floppy. This is done by adding the correct syntax to config.sys and autoexec.bat on the floppy and then booting it... really sorry but this was a while ago and I can't remember what the syntax was (I don't even think I understood it at the time anyway so just copied it from config.sys/autoexec.bat on a working system) so maybe look in those if you have current working DOS/win9X system. I think they were pretty generic settings, other vendors also had their own versions, but mscdex worked for all my CD drives at the time.
I did this regularly because I didn't have an original boot disk (and tended to reuse my boot disk for general data stuff once I had a working system), and my system install cd wasn't an original bootable one (I believe it was a special version which had Memorex 750MB CDR written on it).
I may have an old one in my pile of useless yet sentimental crap. I will have a look in which case I could tell exactly what syntax to add to config.sys and autoexec.bat.
Hope this helps.
