Upgrading From Previous Releases of Device Driver

MEGAPORT/2 & MEGAPLEX/2 Streams Device Driver Version 2.X represents a
major change in the format of the device driver distribution floppy. The SVR4-style
pkgadd
driver must take some additional steps to insure proper installation.
Device drivers formatted to work with the SVR4 pkgadd utility require previously
installed versions to be manually removed before installing this release. If you are
upgrading the Equinox MEGAPORT/2 or MEGAPLEX/2 Streams device driver,
check the version of the currently installed device driver. Follow the appropriate
instructions described below. If you are not sure of the version number installed on
your system, run both sets of procedures. Only one driver will be removed.

Device Driver Version 1.2X and Lower

If you are currently using version 1.2X or lower of the Equinox Streams device
driver, or if you are not sure which version you are using, execute the following
command:
removepkg
command. If an Equinox device driver appears in the list, select the number corre-
sponding to the driver and proceed with driver removal. This procedure removes the
device driver version 1.2x and lower.
Do not rebuild the kernel at this time. The rebuild can be done after the new driver
is installed.
