Command: devicehigh

  DEVICEHIGH loads a driver into high memory,whereas DEVICE loads the 
  driver into low or conventional memory.
  DEVICEHIGH is a CONFIG.SYS / FDCONFIG.SYS command.

Syntax:

  devicehigh=[drive][path]filename [options]
             drive     The drive letter, e.g. C:
             path      The directory, e.g. \example\
             filename  The driver (file) to load, e.g. himemx.exe

Options:

  options  These are options to the driver 
           program, not to the 'device' command.

Comments:

  DEVICEHIGH loads the device driver specified by drive:\path\filename into
  high [ABOVE 640KB] memory (failing that it should load it in conventional
  memory). The options are for the driver itself; refer to documentation
  that came with your particular device for supported options and their
  usage.
  As DEVICEHIGH loads the driver into high memory there remains more free
  space in low or conventional memory for other drivers or for programs.
  To load up a driver or a program into high memory you first have to load
  a driver like (HIMEM), HIMEMX or JEMMEX in CONFIG.SYS / FDCONFIG.SYS.
  DEVICEHIGH is a command internal to kernel.sys and needs no other file
  in order to work.

Examples:

  IN CONFIG.SYS / FDCONFIG.SYS:
    DEVICE=C:\FDOS\BIN\XMGR.SYS /N128 /B
    DEVICEHIGH=C:\FDOS\DRIVERS\UIDE.SYS /S125 /D:MYDVD
  WITHIN A MENU:
    23?DEVICEHIGH=C:\FDOS\BIN\XMGR.SYS /N128 /B
    23?DEVICEHIGH=C:\FDOS\DRIVERS\UIDE.SYS /S125 /D:MYDVD
