E-EQ-MX2RG-L-ARC MX2 Reference Guide
Chapter 3 Software Configuration
Introduction
This chapter details the default contents of the disk drives and the organization of system software
on the MX2. It also includes descriptions of two standard software configurations.
BIOS and DOS
The MX2 uses a modified version of General Software’s BIOS with Datalight’s ROM-DOS. Both
products are burned into system flash in a single 256K image. The A drive is included in the
image, physically addressed just below the BIOS image.
ROM-DOS uses the Datalight command.com processor. This processor is fully Microsoft 6.2
compatible, except that it occupies about half the space in memory. In addition, drive C contains
Datalight DOS files in a DOS subdirectory.
DOS Key Functions Not
Supported on the MX2
Prnt Scrn A function that is available at the DOS prompt on a desktop PC. The Prnt Scrn as a
system function requires a parallel port and the MX2 has only serial ports.
Sys Req A function that is available at the DOS prompt on a desktop PC. Sys Req is for use in
a multi-tasking environment to switch between various running applications. The
MX2 is not a multi-tasking computer, nor is DOS in general considered a multi-
tasking environment.
PC Card and RF Networking Software
PC card device drivers and utilities as well as RF networking solutions are installed on drive C
(the flash drive).
• Default IRQ for PC card is 7.
• Default PC card COM port is COM 2.
