5.1 ROM Disk Configuration
User programs are stored in the MVI-ADM module’s ROM disk. This disk is
actually a portion of Flash ROM that appears as Drive A:.
The ROM disk size is:
This section describes the contents of the ROM disk.
Along with the user application, the ROM disk image must also contain, at a
minimum, a CONFIG.SYS file and the backplane device driver file.
MVI56BP.EXE & MVI56DD.EXE
If a command interpreter is needed, it should also be included.
5.1.1 CONFIG.SYS File
The following lines should always be present in your CONFIG.SYS file:
MVI46
IRQPRIORITY=1
INSTALL=A:\MVI46bp.exe -iomix=0 -class=4 -m0size=3000 -m1size=10000
Note: The MVI46 driver file is called MVI46BP.EXE, and may be loaded from the CONFIG.SYS or
AUTOEXEC.BAT files. The driver must be loaded before executing an application which uses the
MVI API.
The SLC platform supports several classes of modules. The MVI46 can be
configured as a Class 1 or Class 4 module. Also, the I/O image sizes are
configurable. If the MVI46 is configured as Class 4, M0 and M1 files are
supported and their sizes are configurable.
Note: Messaging is only supported when the MVI46 is Class 4.
