12 MultiModem ISI Server Cards User Guide
Chapter 4 – Linux Installation
There are two options for installing Linux drivers:
● For Linux kernel version 2.6.8 or higher, use the driver that it built-in to the Linux kernel. The download
explains how to configure the driver.
● For Linux kernel version 2.4.x, you will need to download drivers from the Multi-Tech Installation Resources
website. Multi-Tech's version 1.01 driver for the ISI Cards works with the 2.4.x Linux kernel. It has been tested
with RedHat Release Versions 7.3, 8.0, and 9.0.
System Requirements, Prerequisites, & Conditions of Use
Category Description
Hardware Platform: Intel x86
Linux kernel version: 2.4.x or later
GNUC Compiler version: 2.72 or later
ISI capacity per computer: Up to 4 boards
Driver type: For Linux kernel 2.4.x, use Multi-Tech driver only; do not use any drivers included with
the Linux OS (like Exar drivers).
For Linux kernel 2.6.8 or higher, use Linux drivers.
Full Linux Installation: For the ISI Card to operate properly, all components of the Linux OS should be installed.
If the ISI Card does not operate properly in a Linux installation where some components
are missing, then those missing Linux components should be added and the ISI Card
should be uninstalled and re-installed.
NOTE: The 'make' utility, the GNU C compiler, and the kernel sources need to be
installed on your system. If any of these are missing, the compilation will fail.
Most later Linux OSs install these elements automatically. For best results, the
Linux OS installation should include all elements.
