Apple Macintosh LC 630 DOS - Manual (Page 129)

The Mac OS is running out of memory even though I’m not running any PC programs.
When sharing memory with the PC environment, the Macintosh allocates a
portion of its memory to the PC. Because of this, the Mac OS may not be
able to load all your system extensions, including the PC Setup control panel.
If this problem occurs, try the following:
m Add memory to the DOS-compatibility card, as described in Appendix B.
m Decrease the shared memory setting.
m Remove PowerTalk and QuickDraw GX from the Extensions folder inside
the System Folder.
m Remove any other system extensions you don’t need.
m Change the name of the PC Setup control panel to !PC Setup so that it
loads first.
Shared memory assigned to the PC isn’t available to the Mac OS until you
turn off the PC. If the previous suggestions don’t solve your problem, click the
Off button at the top of the PC Setup control panel and restart the Macintosh.
My monitor flashes oddly when I switch environments.
This is a natural effect when a single monitor is used by two different
environments. Turn on the Fade Screens option in the PC Setup control panel.
The PC environment is frozen, and pressing Control-Alt-Delete doesn’t reset the system.
Press the x-Control-Alt-[keypad] period keys. The system will reset with a
cold start.
When I print a document in the PC environment, the top and bottom get clipped.
In the Mac OS, open PC Print Spooler in the Extensions folder, choose
Preferences from the File menu, and click “Gaps between pages (60-lines).”
In the PC environment, configure your applications to print to a 60 line page,
rather than a 66-line page, or your margins will be off and your pages will
not print correctly.
