my aim is pretty simple - i just want to boot into any dos type interface and then access the cd drive - e.g e:\setup.exe however all the dos utilities i try cannot seem to browse the cd drive - not even commands such as cd c: - comes up as drive not recognised or some such - i am using ntfs - the drive is formatted - cd drive works fine ... it is a pmcia cd drive on a sony vaio laptop - looking at the docs for the various dos programs looks like this should be supported ... any help thanks :)

Hmm you certainly need to install a DOS driver (install from Config.sys and load through MSCDEX or equivalent through AutoExec.bat ) for your drive... unfortunately I don't know any pcmcia drivers, only IDE ones - maybe there is one on your drive's manufacturer's website ^^
Also make sure there is no LastDrive parameter restricting too much the available letters, for if you have too many partitions you may not have enough letters available for your CD drive(s).

Well in addition, DOS (at least MS) doesn't recognize changing drive using the CD command.
You should use drive_letter: ( for example : " e: " ) to "go" to a drive, and CD only allows to change current directory on active drive.
