Multi Tech Equipment ISIHI-2S Benutzerhandbuch

This section guides you through the Multi-Tech Installation Script for SCO and UNIXWare
systems. The script requests information such as how many boards you want to install,
what I/O address and IRQ values (interrupt requests) you have selected, and how many
pseudo devices you want to create for Multi_View utility. This information extracts the
necessary drivers, which will be linked with your system’s kernel.

1. The first screen requests the number of ISIHI-2S cards you are installing. If you have

more than one ISIHI-2S, use the chart on page 18 of  this guide—Recommended
Base I/O Address and IRQ Values—to enter the appropriate values for each card.
Enter the number of cards and press ENTER.

2. The second screen requests the number of ports. Enter 8 and press ENTER.

3. The third screen requests the base I/O address you selected for the first card you are

installing. It is important to verify that the address you select for each ISI does not
overlap with existing devices or with another ISI. The ISI card uses the base I/O
address and the next fifteen addresses.

Note: If the I/O address you select conflicts with an existing device in your system,
you must remove the ISI driver and re-install it.

Enter the base I/O address and press ENTER. For additional information, refer to the
online manual.

4. The fourth screen requests the IRQ value for this card. Verify that the IRQ you select

for each ISI does not overlap with existing devices or with another ISI. Type the
desired IRQ value and press ENTER.

Note: If you entered a number greater than 1 at the first screen, the previous three
screens reappear in sequence for each card you install. After you enter the
necessary information, installation continues.

5. The fifth screen requests you enter the number of pseudo devices to  create for

Multi_View Utility. Enter the value and press ENTER.

Note: You must enter a minimum of 8 for each board installed.

6. The /dev directory holds device-information files used by the kernel to access the

hardware. When you add an ISI card, you must give the ISI ports unique names, so
they do not conflict with existing ports or other devices known to your system. If you
use an existing device name to identify your new ISI ports, the existing device is
deleted when the ISI port using its name is created.

The default base name for ISIHI-2S ports is ttyl. The default base name for printer
ports is prnl. If this is acceptable, type Y and press ENTER.

To change the base name, type N and provide a prefix of less than five characters.
The base name you select will be used for all ports on each card you install.
