Advanced Setttings

The following settings are available in the SheepShaver_prefs file. Below is a short explanation of how to use them:
For clarity I made the keywords bold and the possible value are just plain text. The keys are not in the same order as in the default settings file.
I don't know the exact meaning of every setting, but you should get a reasonable impression.
Where there is "true" or "false" behind a keyword it means the option can be turned on or of by setting one of these values

rom Mac OS ROM
tells SheepShaver to use the rom file called Mac OS ROM from the location the executable is placed too.
You can change this by adding a path before the rom file name e.g. c:\SheepShaver\Mac OS ROM

disk SheepHD500.hfv
tells SheepShaver to use the hard disk file called SheepHD500.hfv from the location the executable is placed too.
You can change this by adding a path before the rom file name e.g. c:\SheepShaver\SheepHD500.hfv

cdrom h:\
tells SheepShaver to use the cdrom with drive letter h:\

windowmodes 7
this setting controls the set of resolutions you can use in Mac OS. A setting of 7 makes it possible to choose from
640x480
600x800
1024x768

not used, but controles full screen mode

extfs
has no effect in the Windows version, use enableextfs

you can get access to your floppy drive by adding the drive letter in the string of external drives. It then shows up under "my computer"

selects driver to boot with

use 268435456 for 256 MB
