A. BOARD CONFIGURATION
The ZT 8907 includes several options that tailor the operation of the board to
requirements of specific applications. Most of the options are selected through the BIOS
SETUP utility. Some options cannot be software controlled and are configured with
jumpers or cuttable traces. Jumper options are made by installing and removing
shorting receptacles. Cuttable trace options are made by installing and removing
surface mount 0
Ω
resistors.
This appendix is organized according to the three types of configuration options: BIOS
SETUP, jumpers, and cuttable traces. It also provides illustrations showing the locations
of the ZT 8907's jumpers and cuttable traces.
BIOS SETUP OVERVIEW
The ZT 8907 has many features that can be configured with the BIOS SETUP utility.
The SETUP utility is executed during the boot sequence when the
"S"
key is typed. In
DOS systems, SETUP may be executed by running the SETUP.COM program from the
command line.
BIOS SETUP Screens
The BIOS SETUP utility for the ZT 8907 is organized as two screens, listed below.
•
Screen 1:
Generic option list.
Options shared among all Ziatech CPUs are listed on
this screen. Base memory and extended memory size selection, boot source, hard
disk type, and floppy disk type are configurable through this screen.
•
Screen 2:
ZT 8907-specific SETUP options.
Options such as interrupt routing and
STD 32 memory and I/O addressing are configurable through this screen. See the
following topic, "
ZT 8907-Specific SETUP Options
," for more information.
The parameters in the SETUP screens are easily changed. Use the arrow keys to select
a parameter, then press + or - to step through the valid choices for that parameter. A
dynamic help line at the bottom of the screens helps you determine how to set each
parameter. SETUP accepts only valid parameter sets: if changing one parameter
invalidates another parameter, SETUP automatically updates the invalid parameter.
After setting the parameters, press the F10 key to accept them. Press the
Page Down
and
Page Up
keys to switch between SETUP screens.
