![]() It is often used with FreeDOS and works with other DOSes as well. There's a free alternative called SHSUCDX that is used with the IDE/ ATA driver UIDE.SYS first released in 2005. It uses Cloaking to relocate and run in protected mode on 386 and higher processors.Ĭorel offered CORELCDX.COM as alternative to MSCDEX. Ī cloaked variant of MSCDEX was provided as part of Helix Software's Multimedia Cloaking product. An alternative solution, but less flexible, some versions of DR-DOS offer to delay the installation of a driver in CONFIG.SYS until after the DOS data segment relocation via INSTALLLAST.īased on NWCDEX, IMS REAL/32, a successor to Novell's Multiuser DOS and Digital Research's Concurrent DOS, provides a similar driver named IMSCDEX. ![]() In contrast to MSCDEX, the driver does not depend on undocumented DOS APIs and therefore, with a third-party helper tool named INSTCDEX, can be loaded via INSTALL statements and be fully functional in CONFIG.SYS thereby increasing chances to load the driver high and, under these operating systems, allow to load other drivers not only from hard disk but also from CD-ROM while the operating system is still processing CONFIG.SYS. Using EMS with a page frame, NWCDEX can reduce its footprint even down to a few bytes in conventional memory. It has more flexible load-high capabilities, also allowing to relocate and run in protected mode through DPMS on 286 and higher processors, thereby leaving only a 7 KB stub in conventional or upper memory (in comparison to MSCDEX, which occupies some 16 KB). Novell DOS 7, Caldera OpenDOS 7.01 and DR-DOS 7.02 and higher provide a functional equivalent to MSCDEX named NWCDEX, which also runs under MS-DOS and PC DOS. It is implemented as a terminate-and-stay-resident program and an extension to the redirector interface ( CDEX).ĭatalight ROM-DOS includes an implementation of MSCDEX. The driver essentially looks similar to a network drive from the system perspective. This is the reason that at least version 3.1 of MS-DOS is required. The driver uses the Microsoft networks interface in MS-DOS. Starting with Windows 95, CD-ROM access became possible through a 32-bit CDFS driver. The final version of the MSCDEX program was 2.25, included with Windows 95 and used when creating bootable floppy disks with CD-ROM support. This requires the previous loading of an appropriate CD-ROM device driver (example: OAKCDROM.SYS), usually from CONFIG.SYS. The program is a driver executable which allows DOS programs to recognize, read, and control CD-ROMs using the High Sierra and – since version 2.0 as of 1988 – also the ISO 9660 file systems. Earlier versions of MSCDEX since 1986 were installable add-ons for MS-DOS 3.1 and higher.
