5.8 Library Diskette
The EISA architecture is backwards compatible with the ISA architecture.
However, since ISA modules were created and used before ISA CFG files
were created, many ISA modules are in use which were shipped without ISA
CFG files. In order to use these modules in EISA systems, ISA CFG files are
required. To assist users of older ISA modules, many vendors have submitted
ISA CFG files to the EISA consortium. These ISA CFG files are contained on
the library diskette shipped with the SCU. See Appendix E for a list of the ISA
CFG files on the library diskette.
When you install an ISA module for which you have no ISA CFG file, look on
the library diskette. The files are listed by their EISA standard file name, as
well as by the vendor product name. The ISA CFG file for the ISA module can
be installed in the system configuration file. Under the "Add or remove boards"
section of the "Configure computer" main menu selection, you have the option
of inserting the library diskette to search for an ISA CFG file. Files for many
popular ISA CFG files are contained on this diskette.
Note
ISA CFG files contained on the Library Diskette are submitted to
the EISA consortium by individual vendors. Digital Equipment
Corporation has not qualified or tested any of the files on the library
diskette and these files are provided as is.
5.9 Advanced System Configuration Utility Feature
The SCU is equipped with an advanced system configuration utility feature.
With this feature you can allocate memory in the 15 MB to 16 MB range for
use by EISA or ISA I/O option modules. Generally these modules use memory
locations between 640 KB and 1 MB. The advanced SCU feature allows you to
install up to four Digital terminal multiplexers in the system.
Note
The advanced SCU feature can be used only with SCO UNIX System V
Release 3.2 Version 4.0. It is not supported with SCO ODT 1.1, DOS,
or Novell operating systems. Your option module must also support use
of memory in the 15 MB space.
