Command: install / installhigh
INSTALL / INSTALLHIGH runs a TSR program (a program that stays in
memory) without an ENVIRONMENT, instead of using something like LH
or LOADHIGH.
INSTALL loads a TSR program into low or conventional [low 640 KiB]
memory, whereas INSTALLHIGH loads the TSR program into high memory.
INSTALL / INSTALLHIGH is a CONFIG.SYS / FDCONFIG.SYS command.
Syntax:
install=[drive][path]filename [options] OR:
installhigh=[drive][path]filename [options]
drive The drive letter, e.g. C:
path The directory, e.g. \example\
filename The filename of the tsr to run, e.g. test.sys
Options:
options These are the options which will be passed to the TSR. They
are not options for the 'install' command.
Comments:
INSTALL / INSTALLHIGH loads the program specified by drive:\path\
filename. It is generally used to load TSR (terminate and stay resident)
programs with a minimal environment block. The options are for the
program itself; refer to documentation that came with your particular
software for supported options and usage.
As INSTALL loads the driver into low or conventional memory this leaves
less free space for other drivers or programs in low or conventional
memory. This may cause problems when executing programs or loading
other drivers.
Since INSTALLHIGH 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 HIMEMX, JEMM386 or JEMMEX in CONFIG.SYS /
FDCONFIG.SYS.
INSTALL / INSTALLHIGH is a command internal to kernel.sys and needs
no other file in order to work.
Examples:
IN CONFIG.SYS / FDCONFIG.SYS:
install=C:\FREEDOS\BIN\nansi.sys OR:
installhigh=C:\FREEDOS\BIN\nansi.sys
