[1mNAME
     [0mcmos - CMOS RAM driver

[1mDESCRIPTION
     [0mThe battery-backed CMOS RAM in Acorn workstations is used to
     hold various pieces of configuration information, in 240
     bytes of memory.  Such items as attached monitor type,
     bootstrap defaults and Video Console set-up parameters are
     stored here.  The device /_d_e_v/_c_m_o_s provides access to this
     memory by suitably privileged programs.  The CMOS RAM is
     mapped as a contiguous sequence of 240 bytes.  For defini-
     tions of memory usage, see the technical reference manual
     for the model in question.

     The cmos device is implemented as an extra minor device of
     the standard kernel internal device driver which handles
     mem, kmem and null.
