Apple 4400, 7300 manual Troubleshooting

In the PC Setup control panel, make sure the On button is selected. If it is, click Start PC at the bottom of the control panel. If the On button is not selected, click it; then restart your Macintosh. Open the PC Setup control panel again and click Start PC.

If the On button is selected and you have restarted the Macintosh, but the “Switch to PC,” Start PC, and Shut Down PC buttons are not available, there may be a problem with your PC Compatibility Card. Consult your Apple- authorized service provider.

There may be a problem with an additional DIMM installed on your PC Compatibility Card. Open the PC Setup control panel and check the RAM portion of the control panel. If no DIMM is indicated and you have installed an additional DIMM, remove it and restart the computer. If a DIMM is detected by the PC Setup control panel, you can still remove it and restart the computer. For more information on adding and removing DIMMs, see Appendix C, “Adding Memory to Your PC Compatibility Card.”

When I start up the computer it goes directly into the PC environment.

If you don’t want the PC environment to start automatically, return to the Mac OS environment by pressing x-Return. Open the PC Setup control panel and make sure the “Switch at Startup” box is not checked.

DOS begins to start up but then the screen freezes. The cursor blinks, but I cannot type anything.

Press x-Control-Alt-…to restart the PC. (If you do not have the … key on your keyboard, use the period key on the numeric keypad.) When you see the message “Starting MS-DOS” or “Starting Windows 95,” follow this step to bypass your CONFIG.SYS and AUTOEXEC.BAT files:

DOS or Windows: Press and hold the Shift key.

Windows 95: Press and hold the F5 key.

After the PC has started up, check the CONFIG.SYS and AUTOEXEC.BAT files, change any incorrect lines, and then restart the PC.
