The supported switches and their meaning are as follows:
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.ex t Writes the specified file to the board’s CMOS
RAM and configuration EEPROM. Drive and
path are optional in the file name.
Wfile.ex t Write CMOS RAM and EEPROM contents to
the file specified. The file name may contain
an optional drive and path.
Table 3-5 SETUP.COM Command Switches
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/486i 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.
3.8 OPERATION WITH DOS
The Little Board/486i supports IBM’s PC-DOS or Microsoft’s MS-DOS, Version 3.3 or later, or any
version of Digital Research’s DR DOS as the disk operating system. Any differences between these
similar operating systems are noted in the text where applicable.
Caution
Sometimes MS-DOS is customized by a manufacturer for a specific
system and may not work on the Little Board/486i. Use DR DOS
(supplied by Ampro), IBM PC-DOS (supplied by IBM), or the
generic version of MS-DOS (supplied by Microsoft on an OEM
basis).
