Troubleshooting
The distribution software contains test programs called RTTEST32.EXE and RTTEST16. They verify the
port address, its reliable at the selected transfer speed and the emulator’s functionality as well as proper
installation of the ring-0 drivers. The first step in troubleshooting is to run this program and make special
note of any problems it reports.
Regardless of the symptom, verify the following:
1.
2.
3.
4.
5.
6.
There are no “dongles”, security keys, switch boxes or other devices between the FlexROM III
download cable and the printer port.
Try each available printer port configuration. Some ports work best in STANDARD, AT, NIBBLE or
COMPATIBLE mode. Others may provide more reliable high-speed operation when set to ECP, EPP,
PS2, Bi-directional or HIGH-SPEED mode.
The target is powered up or an external power supply is connected to the emulators
All download, daisy-chain and target interface cables are tight and fully inserted.
The selected printer port is not being serviced by a print spooler or some type of TSR.
If the PC is a laptop or a “GREEN” PC, verify that the printer port is not disabled, powered down or
configured for any type of power savings mode.
In all cases, try “booting” clean from a DOS diskette to see if the symptoms disappear. If the 16bit loader
and self-test programs work under this condition, chances are good that some other program is interfering
with our access to the printer port.
DLL not found or DRIVER not found
Drivers not properly installed
The 32bit software versions require our ring-0 drivers. These are automatically installed into the correct
directories and added to the windows registry when you use our SETUP.EXE program. You must run
SETUP.EXE install the files onto a computer. Just COPYING the files will not properly register them with
Windows.
Under NT and 2000, you must have ADMINISTRATIVE/Supervisor PRIVILEGES to properly install the
drivers and update the registry.
Failed to re-boot after installation
The drivers will not become active until after you re-boot. Sorry, as much as we hate the ‘reboot windows
for this to take affect’ syndrome, its just the way it works.
