This option enables support for file transfers from a Hardware
Management Console (HMC) drive CD/DVD-ROM. It is available as a
module, called 'hmcdrv', and also as kernel built-in. There is one
optional parameter for this module: cachesize=N, which modifies the
transfer cache size from it's default value 0.5MB to N bytes. If N
is zero, then no caching is performed.
