drive The drive letter, e.g. C:
path The directory, e.g. \example\
filename The driver (file) to load, e.g. himemx.exe
options These are options to the driver
program, not to the 'device' command.
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
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.
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
