Troubleshooting

SheepShaver doesn't boot

SheepShaver should boot all MacOS versions >=7.5.2, except MacOS X. However, your mileage may vary. If it doesn't boot, try again with extensions disabled (by pressing the shift key) and then remove some of these extensions: "MacOS Licensing Extension", Speed Doubler, 68k FPU extensions and MacsBug.

The colors are wrong in 16 or 32 bit graphics modes

If you're running SheepShaver on a BeBox, the only graphics modes that have the right colors are the 8 bit modes (this is actually a hardware problem and has to do with frame buffers being little-endian on the BeBox), unless you are using a Matrox Milennium I/II.

You should also be aware that not all graphics cards support 16 bit modes under BeOS (especially S3 cards don't). Check the BeOS "Screen" preferences application to see if your card does.

SheepShaver appears to be very slow

Full-screen mode doesn't work

If your machine uses the "IXMicro" BeOS video driver (TwinTurbo cards), you will have to disable the "QuickDraw Acceleration" in the "Video" pane of the SheepShaver settings.

Ethernet doesn't work

SheepShaver crashes, but yesterday it worked

Try the "Zap PRAM File" item in the main menu of the SheepShaver preferences editor. When you are using a ROM file and switching to a different ROM version, you have to zap the PRAM file or SheepShaver might behave very weird.
