Other Configurations
It is possible to run your Echo board using I/O addresses and
interrupts other than those listed above. In order to do this, it will
be necessary to modify certain system files. Consult the "Release
Notes" section of your operating system manuals or contact
Connect Tech's Customer Support for more information.
Technical Tips
If you experience difficulties installing your Echo adapter try the
following steps:
1. Check to see if you have followed the above procedures
closely.
2. Check for conflicting devices in your system. It is possible
that there is a conflict between the Echo adapter and
another board in the system. This could be an IRQ or I/O
port conflict. Try using the porttest.exe and portfind.exe
found on the DFlex DOS Driver diskette (p/n: DISK306) to
find the hardware conflicts.
3. If you use a system with a Plug and Play(PnP) BIOS or PCI
bus, you might have to configure the CMOS setup for non-
PnP devices like the Echo adapter.
4. If you need to remove/un-install the Echo, you should use
the mkdev serial utility and follow the options for (r) remove
a board. If you decide that the Echo adapter is not working
due to a conflict, you should remove the board with mkdev
serial, reboot and then run mkdev serial to install the Echo at
some alternate settings.
