### Installing the Driver: Downloaded (RPM Methods)

Use this information to choose the most appropriate procedure to install a Linux driver that you have downloaded from the Digi ftp site. This procedure will install the driver, but you must configure and start the driver before you can use your Digi product. See Configuring and Starting the Driver.

Note: These procedures should be used only in Linux environments that support the installation and building of packages from an RPM repository. The procedures require that the following RPM directories exist and are used by RPM on your Linux system.

/usr/src/redhat/BUILD
/usr/src/redhat/RPMS
/usr/src/redhat/SOURCES
/usr/src/redhat/SPECS
/usr/src/redhat/SRPMS

#### Package Version and Revision

Certain commands used in the following procedures need to be entered with the correct package version and revision number.

Note: To determine package version and revision numbers, use this command:

`rpm -qp filename`

Example:

If the package version of the Linux driver is 1.0 and the revision is 2, then:

For this command variable: | This value would be used:
--- | ---
version | 1.0
revision | 2
For this command: | This would be entered:
rpm -ivv epca-version-revision.src.rpm | `rpm -ivv epca-1.0-2.src.rpm`

#### Installation Methods

Choose one of the two methods for installing the driver with RPM:

Method | Description
--- | ---
Custom Installation Procedure | This method is intended for use by users who wish to customize the installation (for example, to change the destination directories of certain tools). This method is the most complex and should be used only if necessary.
