What should I type into the pop-up window that appears when I start wibconf?
This pop-up window is prompting you for the drive and path where the gpib.ini file is
located. If Windows is installed in the default directory (c:\windows), just press
<Return>. If Windows is not installed in the default directory, enter the path and
directory where Windows is installed so that wibconf can find the correct gpib.ini
file to modify, for example c:\win31\gpib.ini.
How can I determine which type of GPIB board I have installed?
Run the GPIBInfo utility. If you run GPIBInfo without specifying any parameters, it
returns information about the GPIB boards currently configured for use in your system.
If you know the base I/O address of a GPIB interface board, you can enter it as a
parameter for specific information. For example, gpibinfo 2C0 returns information
about the GPIB board at base I/O address 2C0.
How can I determine which version of the NI-488.2 software I have installed?
Run the GPIBInfo utility. If you run GPIBInfo without specifying any parameters, it
provides information about the version of the NI-488.2 software currently installed.
Why can't I launch Windows after installing Windows 3.1 on top of my
Windows 3.0 installation?
If the system.ini file contains conflicting information about which virtual devices to
load, Windows fails to start. In this case, the system.ini file is probably trying to
load two virtual DMA devices. The system.ini file should include the lines to load
only one virtual DMA device. You can either delete unwanted lines or change them to
comment lines by adding a semicolon at the beginning of the line.
The virtual DMA device is loaded in the [386Enh] section of the system.ini file.
The correct one to use with Windows 3.1 is loaded by the following line:
device=*vdmad
The correct one to use with Windows 3.0 is loaded by the following line:
device=drive:\path\nivdmad.386
where drive and path describe the location of the nivdmad.386 file on your hard
disk (for example c:\at-gpibw).
