Ampro Corporation 486E manual Creating Configuration Files with SETUP.COM, Switch Function

Little Board™/486e Technical Manual

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.

Switch Function

?Display a usage help screen

TSet 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.
