# Using SheepShaver

## Changing the display mode

SheepShaver can display the MacOS user interface in a BeOS window or full-screen (much faster) in several resolutions and color depths. You select the display mode as usual under MacOS in the "Monitors" control panel (under System 7.x, click on "Options"). The "75Hz" modes are full-screen modes, the "60Hz" modes are window modes (this doesn't mean that the video refresh rate is 75 or 60Hz in the respective modes; the rate displayed has no meaning; it's simply there to distinguish full screen modes from window modes).

## Window mode

The SheepShaver window has a menu at the bottom that allows you to change the graphics refresh rate and to mount floppy disks (see below). The window refresh is disabled as long as the "Scroll Lock" key is pressed (the graphics output is then frozen).

## Full-screen mode

The full-screen mode uses a whole BeOS workspace for displaying the MacOS user interface. You can switch workspaces with Command-F1/F2/F3/etc. Please note that the MacOS (and all MacOS applications) will be suspended when you switch to a different workspace. It will only be resumed when you go back to the SheepShaver workspace.

## Networking

SheepShaver only supports Ethernet networking (and PPP via the serial ports). If there are multiple Ethernet cards installed, only the first card will be used. The Ethernet support is implemented at the data-link level. This implies that the "Mac" and the "Be" side must have two different network addresses.

## Using floppy disks

Floppy disks are not automatically detected when they are inserted. They have to be mounted explicitly. After inserting a floppy disk, select the "Mount Floppy" item in the "SheepShaver" menu (when running in window mode), or press Ctrl-F1 (when running in full-screen mode). BeBox users should note that floppy disks also have to be unmounted under MacOS before ejecting them from the drive.

## Accessing BeOS files

SheepShaver will display a "BeOS" disk icon on the Mac desktop that allows you to access any BeOS files/folders which are in the directory specified as "BeOS Root" in the "Volumes" pane of the SheepShaver settings. You can open and save files on the "BeOS" disk from Mac applications, copy, move or rename files from the Finder etc. Putting files/folder to the trash may however not always work. SheepShaver translates some BeOS file types to MacOS types and vice versa, so e.g. JPEG and PDF files will show up the correct icons in the Finder. To store Mac resources and other additional data, SheepShaver uses the following BeOS file attributes:

- `MACOS:RFORK` contains the complete Mac resource fork of the file
- `MACOS:HFS_FLAGS` contains Finder flags
- `MACOS:CREATOR` contains the MacOS creator application ID

## Copying text via the clipboard

SheepShaver tries to keep the BeOS and MacOS clipboards synchronized. That means, when you copy a piece of text under BeOS, you can paste it into a MacOS application and vice versa.
