Not in DOS (real) mode, but if you mean the Command Prompt, yes.
imdisk -a -f \\server\share\file.iso -m F:
This will mount as a virtual CD drive F: from the command line in Windows. I don't know of any way to do this in real mode DOS.

If you are talking about "real" DOS, you will need to get SHSUCD set of programs:
http://www.geocities...ucdx/index.html

Although only SHSUCDX (MSCDEX replacement) is widely known, there are also:

SHSUCDHD:
emulates a CD-ROM using an image file. v3.01
SHSUCDRD:
emulates a CD-ROM using an image file in memory. v1.00
SHSUDVHD:
emulates a DVD-ROM using multiple image files. v1.00
SHSUCDRI:
emulates a CD-ROM using an image created in memory. v1.00
OMI:
creates an image file from a CD or DVD. v1.00
ISOBAR:
extracts the boot image from a bootable CD or image. v1.01

P.S.: just as a reminder, and for future memory, MSCDEX can ONLY read CD's with iso level up to 3.
PE CD's that are usually made with iso level 4 NEED to be accessed through SHSUCDX.

In other words, MSCDEX was released before the ISO9660 1999 extensions became a standard.

Check out http://www.geocities...ucdx/index.html

Please note SHSUCDHD allows you to mount the .ISO but not boot from it. BCDW has limited support for .ISO booting and GRUB4DOS may have, er, something.. I've never quite wrapped my puny little brain around how to use it :yahoo:

Sorry, Moon Goon, cross-posting.

For the record, some discussions on this were already made here:
http://www.boot-land...ible-t1946.html
http://z3.invisionfr...p?showtopic=155

Grub4dos has NOT (yet) official support for .iso files.
Check these:
http://www.911cd.net...o...18045&st=45
http://www.911cd.net...o...18045&st=61

I never found a report of success (actually booting) anywhere, it is possible that it works on some .iso only but for the moment I guess it's ALPHA.
