Load MSCDEX From CONFIG.SYS

Is it possible to do this ?

ie load it sooner than from autoexec.bat in order to provide the CD-ROM support sooner ?

I haven't thought of doing that, and I'm not sure of the purpose, other than to be able to load device drivers from a CD.

Some of the old memory resident utilities that are EXE files like FASTOPEN or KEYB can be loaded in CONFIG.SYS with the INSTALL= instruction. I can't say if it would work with MSCDEX though. I guess you could try, remember the CD device driver will have to be loaded first for it to work.

I think INSTALL loads the program somewhat differently, maybe with regard to the PSP, so the program may need to have been written with this in mind.

INSTALL will only load into low memory, so if it does work, available memory for programs will be correspondingly reduced compared with LOADHIGH from AUTOEXEC.BAT.

As far as I know the code in MSCDEX.EXE is not compatible with CONFIG.SYS protocols. I would guess that there is a way to write a file that would load the CDROM from the config.sys, even as RAMDRIVE loads and assigns a drive letter.

What are you trying to do? If you make a boot CD, you can have access to the CD without any CDROM drivers. It will, however, be identified as C drive. With Nero you can select the floppy drive for a boot image or a hard drive partition. The partition must be small enough to fit on the CDROM. I use a 540mb hard drive for such experiments.
