DOS Drives
Drive Description
Drive A This drive is a 64K block of flash memory that is a read-only DOS boot
drive. You can configure drive A, but you cannot write to it within an
application. Drive A is created and initialized once you run the DOS.BIN
application.
Drive B This drive is an optional read/write DOS drive that resides as a
subdirectory on drive C. Drive B is limited by the space available on drive
C. You can configure drive B by modifying the DRIVEB.IMG file that
defines the ROM-DOS commands available on the terminal. For help, see
"Customizing Drive B" on page 324.
Drive C This drive is a 2MB flash drive. You can use up to 750K of this flash drive
to store up to 128 files, which includes drive B. DOS .EXE applications
must be stored on drive C. You use standard ANSI C library interface
definitions to access the information on this drive.
The following DOS files are installed originally on drive C.
File Definition
DOS.BIN This application reboots and runs ROM-DOS on a Trakker Antares
terminal so that you can run DOS .EXE applications.
ROM-DOS.IMG This file is the image file for ROM-DOS version 6.22.
DRIVEB.IMG This image file contains the contents of DOS drive B. You cannot
reference drive B from a Trakker Antares .BIN application file. If you
delete this file, you lose drive B and the ROM-DOS commands that
are defined for drive B.
Note: If you do not want to use DOS on the Trakker Antares terminal,
you can save space by deleting DOS.BIN, ROM-DOS.IMG, and
DRIVEB.IMG from drive C.
DOS RAM Drive
This drive is a configurable DOS RAM drive. The contents of this drive
are erased when you boot or reset the terminal. You use standard ANSI C
functions to access the files on this drive. If you configure a DOS RAM
drive, DOS assigns drive C to the RAM drive and reassigns the remaining
Trakker Antares drives. For example, the Trakker Antares drive C becomes
drive D. For help creating a DOS RAM drive, see "Configuring a DOS
RAM Drive" on page 325. By default, the RAM drive is not configured
and the memory is available for programmable (Malloc) memory.
There are two types of RAM drives that are mutually exclusive depending
on whether you run native Trakker Antares .BIN applications or DOS
.EXE applications. You use the standard RAM drive E for .BIN
applications or you use a DOS RAM drive for DOS .EXE applications.
Before you start using DOS on the terminal, you must disable the
standard RAM drive. For help, see "RAM Drive Size" on page 223.
