Label is a name used to identify a disk..
On ms-dos, label was queried using the command VOL (volume).
To change a label, the command LABEL was used.
To see (and probably change) label (volume name) under windows, you just have to access its properties (right click).
Enough of theory. Let's asume the cd-rom is labeled BIOFORGE (who could have guessed it! :LOL:), so you should mount your cd-rom drive something like this... (remember: ISO image is loaded at virtual drive E)
mount d e:\ -t cdrom -ioctl -label BIOFORGE
Then, you would have a D: (cd-rom drive) with a cd-rom inserted named BIOFORGE (mind you, some programs/games use label for checking the correct disk).
