The SETUP.COM Program
The SETUP.COM utility can be used from the command line to access the same SETUP functions
as the hot key code, CTRL-ALT-ESC. SETUP.COM also adds additional functionality, such as the
ability to load and store configuration settings to a disk file. This same feature is used to store
OEM information in the configuration memory EEPROM. SETUP.COM is on the Ampro Common
Utilities diskette, included with the Little Board/486e Development Kit. See the Ampro Common
Utilities manual for more information regarding SETUP.COM usage.
Creating Configuration Files with SETUP.COM
The Ampro SETUP utility, SETUP.COM, offers the following options for command line entry:
SETUP [-switches] [ @file.ext | Wfile.ext ]
The supported switches and their meaning are shown in Table 2–59.
Table 2–59. SETUP.COM Command Switches
Switch Function
? Display a usage help screen
T Set the (hardware) real-time clock time and date from the current
DOS time and date.
@file.ext Writes the specified file to the board’s CMOS RAM and configuration
EEPROM. Drive and path are optional in the file name.
Wfile.ext Write CMOS RAM and EEPROM contents to the file specified. The
file name may contain an optional drive and path.
You can save a copy of the current contents of the board’s configuration memory to a disk file by
using the W switch. The data saved includes the entire contents of the nonvolatile configuration
EEPROM. The first 512 bits are the SETUP information (excluding time and date), the next 512
bits are available for OEM storage. See Ampro Application Note AAN-8805 for a description of how
to use the OEM storage portion of the EEPROM.
The file you create with this menu option can be used as a source for programming the
configuration memory of a Little Board/486e CPU at a later time.
As an example, the following command initializes the EEPROM values with a previously saved
configuration:
C>SETUP @SYSTEM.A
Assuming you created the file SYSTEM.A with SETUP’s write option, SETUP will initialize the
EEPROM configuration memory using the contents of SYSTEM.A.
Using SETUP with the write and read parameters can be useful when many boards must be
initialized automatically, or when you want to change between several predefined system
configurations.
