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