Troubleshooting - 3Com 3C389 User Manual

5
Check this list of possible error conditions if problems
occur:
Make sure that the 3C389 PC Card is correctly
installed. See Chapter 3 for details.
When you are using EMM386.EXE or another memory
manager.
When EMM386.EXE and the LAN device driver are
using the same memory, contention occurs and the
3C389 PC Card will not function correctly. If you are
using Card Services, check to be sure that the memory
that Card Services controls is excluded by the memory
manager. If you are using a point enabler, be sure that
the memory that you use is excluded by the memory
manager. As a quick test, you may want to comment
out EMM386.EXE in your CONFIG.SYS, reboot, and try
the 3C389 PC Card again.
If the 3C389 PC Card functions, you will have to edit
the EMM386.EXE command to exclude some memory.
The 3C389 PC Card uses 8 KB of memory in two
separate areas. These memory areas may be
consecutive. See Appendix A, "Using a Memory
Manager" for more information.
If are using Card Services.
During reboot, you hear four alternating tones which
indicates that Card Services was unable to give you
one or more resources (I/O ports, interrupt level, and
memory locations) that your program requested.
