CD-ROM v2.00+ - GET MSCDEX.EXE VERSION (GET VERSION)

AX = 150Ch
BX = 0000h

Return:
BH = major version BL = minor version

Notes: MSCDEX.EXE versions prior to 2.00 leave BX unchanged, thus BX should be 0000h on entry. Corel's CORELCDX.COM v1.01d returns 2.20, v1.12a returns 2.21. Meridian Data's CDNETEX.EXE returns its own version number, e.g. 4.70. J.M.A. Hall's CDEMU2.COM returns 2.10 (it is an MSCDEX emulator for networked CD-ROM drives). Windows95 returns v2.95. Novell DOS 7 NWCDEX.EXE returns the same version number reported in its startup message
