Can anyone explain the difference between the various forms of
disk buffering available under OS/2?  In particular, what is the
difference between:

    (a) The BUFFERS parameter in CONFIG.SYS?
    (b) The DISKCACHE parameter in CONFIG.SYS?
    (c) The /c switch in installing HPFS?

How do these affect operation of

    (a) A FAT fixed disk filesystem
    (b) A HPFS fixed disk filesystem
    (c) A floppy disk filesystem

Also, what if anything does all this have to do with machines that are
advertising as having a disk controller with a built-in cache.

Thanks to all disk buffering mavens.
