If you use MSCDEX to interface with the CDROM, then check out function 
15h of Interrupt 2Fh (I suggest reading about them in Ralf Brown's 
Interrupt List).  For instance, subfunction 02 returns the copyright file 
of the CDROM volume, subfunction 0Ch returns the version of MSCDEX, etc.  
I don't know if those work with other CDROM drivers, but at least some of 
them should.
