ISA Bus

The ISA (Industry Standard Architecture) bus is an industry-standard, 16-bit I/O bus. The
EISA bus is a superset of the well-established ISA bus and has been designed to be
backward compatible with 16-bit and 8-bit architectures. Therefore, ISA modules can be
used in your system, provided the operating system supports the device.
Two EISA or ISA modules can reside in the EISA bus portion of the system board. Figure
6-15 shows the location of the ISA option slots on the system board.
To access the system board, you need to remove the top and left panels of the system
enclosure. Be sure to replace the panels before attempting to turn on the system again.
_________________________Caution____________________________
Do not remove the system's top panel when the system is running. If you do so
without first properly turning off the system, the system will shut down, with
potential loss of data.
____________________________________________________________
For information about installing a specific option, refer to the documentation for that
option. For information about configuring an ISA option, refer to the sections, "EISA
Configuration Utility (ECU)" and "Configuring ISA Options" later in this chapter.
________________________ Warning ___________________________
Before installing ISA bus options, turn off all power to the system. Refer to
"Turning the System Off" in the Chapter 4, "Basic Operations" for information
about turning off power.
