Apple PC Compatibility Card 7-inch card - Manual (Page 137)

I can’t copy files from the Mac OS to a drive container currently in use by the PC.
You cannot copy files while the PC is running. Shut down the PC and try
copying the files again.
I can’t connect to a network in the PC environment.
Make sure that your networking software is properly installed and configured
(see the section on installing network support for Windows or Windows 95 in
Chapter 4, “Installing the PC Compatibility Card Software,” and see
Appendix B, “Installing Network Client Software”).
Make sure the network is up and running (check the Chooser and check with
your network administrator).
On some Macintosh models (for example, Power Macintosh 7200/75, 7200/90,
7500/100, 8500/120, 9500/120, 9500/132), you cannot use the same networking
protocol simultaneously in the PC and the Mac OS. Make sure that different
networking protocols are selected in the Mac OS and PC environments. Some
models allow you to use TCP/IP simultaneously in both environments.
My PC communications software doesn’t work.
The Macintosh and the PC use slightly different serial port protocols, and
some commands do not work. See “Setting Up a Modem or Other Serial
Device” in Chapter 5.
Configuration problems
I can’t assign RAM from my Macintosh to the PC.
Your PC Compatibility Card can only use RAM installed on the card. You
cannot assign it RAM from your Macintosh. You can increase the RAM in the
PC Compatibility Card by adding a DIMM or replacing the existing DIMM
with a larger DIMM. For instructions, see Appendix A, “Adding Memory to a
PC Compatibility Card.”
I can’t assign a COM port to a Macintosh serial port.
COM ports cannot be assigned to Macintosh serial ports that are in use by an
application or network software.
If you assign a COM port to a Macintosh serial port, the serial port cannot be
used by the Mac OS until you unassign the COM port and restart your PC.
