Apple Macintosh LC 630 DOS - Manual (Page 65)

If you want to use the TCP protocol in the PC environment, remove MacTCP
from the Control Panels folder or select an interface other than Ethernet in
the MacTCP control panel.
Network performance is improved by adding memory to the DOS-
compatibility card installed in your computer, as described in Appendix B.
For more information, see Appendix E, “Installing Network Management
Software.”
Using multimedia, MIDI, and game application programs
These types of programs, whether they are run in the PC or Macintosh
environment, see a marked performance improvement when there is a
memory SIMM on the DOS-compatibility card for the exclusive use of
the PC environment. See the Technical Specifications booklet to determine
whether your computer has a SIMM installed on the DOS-compatibility card.
You can also install a SIMM with greater memory capacity, as described
in Appendix B, “Installing an Expansion Card or Memory for the PC
Environment.” QuickTime application performance is especially improved
with a SIMM.
Some DOS-based MPEG players require a VGA monitor to output video. All
VGA modes can be displayed on Macintosh monitors supported by the DOS-
compatible Macintosh. If the monitor specified to display the PC is a VGA
monitor, select VGA in the Display box in the PC Setup control panel. You
cannot select VGA for a shared monitor configuration from the PC Setup
control panel if your monitor is not capable of displaying VGA. Multiscan
monitors can display VGA.
