<H2>SheepShaver doesn't boot</H2>
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
<H2>The colors are wrong in 16 or 32 bit graphics modes</H2>
|
||
|
|
|
||
|
|
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.
|
||
|
|
<P>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.
|
||
|
|
|
||
|
|
<H2>SheepShaver appears to be very slow</H2>
|
||
|
|
|
||
|
|
<UL>
|
||
|
|
<LI>Don't use the window modes, the fullscreen modes are much faster.
|
||
|
|
<LI>If you nevertheless want (or have) to use a window mode, you should set the
|
||
|
|
color depth in MacOS to the same as the BeOS workspace you are running SheepShaver on
|
||
|
|
(e.g. if you are on a 16-bit workspace, set the color depth in MacOS to "Thousands").
|
||
|
|
Also, set the window refresh rate to a low value (high values like 30Hz will make SheepShaver
|
||
|
|
(and BeOS) slower, not faster!).

<H2>Full-screen mode doesn't work</H2>
|
||
|
|
|
||
|
|
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.

<H2>Ethernet doesn't work</H2>
|
||
|
|
|
||
|
|
<UL>
|
||
|
|
<LI>Is the Ethernet set up under BeOS? Ethernet will not work in SheepShaver if you didn't set it up in the BeOS "Network" preferences.
|
||
|
|
<LI>If you're using TCP/IP on the MacOS side, you have to set up different IP addresses for the BeOS and for the MacOS.
|
||
|
|
<LI>Try disabling AppleTalk in the BeOS Network preferences (there might be conflicts between BeOS AppleTalk and SheepShaver networking).

<H2>SheepShaver crashes, but yesterday it worked</H2>
|
||
|
|
|
||
|
|
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 <B>have</B>
|
||
|
|
to zap the PRAM file or SheepShaver might behave very weird.
