     rdconfig - configure RAM disks

SYNOPSIS    [Toc]    [Back]

     rdconfig special_file 512-byte-blocks

DESCRIPTION    [Toc]    [Back]

     The rdconfig command configures RAM disk devices.   It  will
associate the
     special file special_file with a range of user-virtual memory allocated
     by the rdconfig process itself.  The rdconfig command should
be run in
     the background.  If successful, the command will not return.
Otherwise,
     an error message will be printed.

     To "unconfigure"  the  ramdisk,  just  kill  the  background
rdconfig process
     started earlier.
