I have no info as to what to use as an identification
entry for the LiteOn drive ---- hopefully, someone in the forum
will know the correct identification symbol for the LiteOn model,
noted in my posting.

If you mean the string to use where you currently use "PLEX0001", I
thought that was aribitrary, that you could use anything as long as it
agreed in both autoexec.bat and config.sys.

Maybe SYMCD.SYS isn't compatible with the Lite-On?

Maybe you don't have enough low memory to load the driver. Try
installing HIMEM.SYS and EMM386.EXE and loading the CD driver like this
(although I think it will usually load high on its own if it can):

LOADHIGH DEVICE=A:\SYMCD.SYS /D:PLEX0001
