<H1>Setting up SheepShaver</H1>

In the "SheepShaver Settings" window that pops up when you double-click on
the SheepShaver icon, you can configure certain features of SheepShaver.
When you click on <B>"Start"</B>, the current settings are saved to disk and will be
available next time you start SheepShaver.

<P>The settings are divided into four groups: Volumes, Graphics/Sound, Serial/Network and Memory/Misc.

<H2>Volumes</H2>

<IMG SRC="volumes.gif">

<P>The main part of the volumes pane is a <B>list</B> that contains all volumes to be mounted
by SheepShaver. If this list is empty, SheepShaver will try to detect and mount all HFS partitions
it can find. CD-ROM drives are always automatically detected and used.

<P>SheepShaver can use HFS partitions, whole HFS formatted drives, and it can also
emulate hard disks in single BeOS files ("hardfiles").

<P>To add a Mac volume to the list, mount it on the BeOS side, click on <B>"Add..."</B>, go to the "Disks"
level in the topmost popup menu of the file panel, click once on the volume you want and
click on "Add". A line beginning with "/dev/disk/" should then appear in the volume list.
After adding volumes to the list, you should unmount them on the BeOS side again.To remove
a Mac volume, select it in the list and click on <B>"Remove"</B>.

<P>You can create a new, empty hardfile by clicking on <B>"Create..."</B>. Enter the file
name and the size of the hardfile and click on "Create". The hardfile will be created (this may
take some seconds) and added to the volume list. The so-created hardfile will have to be
formatted under MacOS before you can store something in it. If you start up SheepShaver,
the Finder will display a message about an "unreadable" volume being found and give you the
option to format it.

<P>Double-clicking on an entry in the volume list will add or remove a "*" in front of the
device name. Volumes marked with a "*" are read-only for the MacOS under SheepShaver.

<P>SheepShaver will show a "BeOS" disk icon on the Mac desktop that allows access to BeOS
files from Mac applications. In <B>"BeOS Root"</B> you specify which BeOS directory will
be at the root of this virtual "BeOS" disk. You can enter a path name here or drag and drop a
Tracker folder onto it. The default setting of "/boot" means that the "BeOS" icon in the MacOS
Finder will correspond to your BeOS boot volume. If you want to access files on other BeOS
volumes, you should enter "/" here. The "BeOS" disk will then contain folders for each BeOS
volume (among other things). The MacOS will create files and folders like "Desktop", "Trash",
"OpenFolderListDF" etc. in the directory you specify as "BeOS Root". If they annoy you, you
can delete them.

<P>To boot from CD-ROM, set the <B>"Boot From"</B> setting to <B>"CD-ROM"</B>.
The <B>"Disable CD-ROM Driver"</B> box is used to disable SheepShaver's built-in CD-ROM driver.
This is currently of not much use and you should leave the box unselected.

<H2>Graphics/Sound</H2>

<IMG SRC="graphics.gif">

<P>WIth <B>"Window Refresh Rate"</B> you can set the refresh rate of the MacOS window.
Higher rates mean faster screen updates and less "sluggish" behaviour, but also require more CPU time.

<P>The <B>"QuickDraw Acceleration"</B> box should always be enabled. It allows for faster graphics in
full-screen modes. But if your machine uses the "IXMicro" BeOS video driver, you have to disable the
QuickDraw acceleration or full-screen modes won't work (this is because of BeOS bug #981112-032247).

<P>The main part of the window is occupied by a list of checkboxes that allows you to select
which <B>graphics modes</B> are available for displaying the MacOS desktop. You can, for
example, disable the modes that your monitor or graphics card can't display, or disable the
window modes when you want to run some Mac programs in full-screen mode that would otherwise
erroneously switch to a window mode. The actual mode to be used is selected in the "Monitors"
control panel under MacOS.

<P>The <B>"Disable Sound Output"</B> box allows you to disable all sound output by SheepShaver.
This is useful if the sound takes too much CPU time on your machine or to get rid of warning
messages if SheepShaver can't use your audio hardware.

<H2>Serial/Network</H2>

<IMG SRC="serial.gif">

<P>You can select to which ports the MacOS <B>modem and printer ports</B> are redirected.
This doesn't make much sense on a PowerMac, but on a BeBox you can assign the modem
and printer ports to any of the four serial ports (or com3/com4) or even parallel ports of
the BeBox (useful for printing if you have Mac drivers for parallel printers, like the PowerPrint
package from <A HREF="http://www.gdt.com">www.gdt.com</A>).

<P>If you don't want SheepShaver's Ethernet support to be enabled for some reason, you
can use the <B>"Disable Ethernet"</B> checkbox to disable it (this will also get rid of the annoying
"no network hardware" messages if your Mac is not equipped with Ethernet).

<H2>Memory/Misc</H2>

<IMG SRC="memory.gif">

<P>With <B>"MacOS RAM Size"</B> you select how much RAM will be available to the MacOS
(and all MacOS applications running under it). SheepShaver uses the BeOS virtual memory system,
so you can select more RAM than you physically have in your machine. The MacOS virtual memory
system is not available under SheepShaver (i.e. if you have 32MB of RAM in your computer and
select 64MB to be used for MacOS in the SheepShaver settings, MacOS will behave as if it's running on
a computer that has 64MB of RAM but no virtual memory).

<P>The <B>"Ignore Illegal Memory Accesses"</B> option is there to make some broken Mac
programs work that access addresses where there is no RAM or ROM. With this option unchecked,
SheepShaver will in this case display an error message and quit. When the option is activated,
SheepShaver will try to continue as if the illegal access never happened (writes are ignored, reads
return 0). This may or may not make the program work (when a program performs an illegal access,
it is most likely that something else went wrong). When a Mac program behaves strangely or hangs,
you can quit SheepShaver, uncheck this option and retry. If you get an "illegal access" message,
you will know that something is broken.

<P>If the <B>"Don't Use CPU When Idle"</B> option is enabled, SheepShaver will try to reduce
CPU usage to a minimum when the MacOS is doing "nothing" but waiting for user input. This doesn't
work with all programs and it may confuse the timing of some games but in general you should
leave it enabled.

<P><B>"ROM File"</B> specifies the path name of the Mac ROM file to be used. If it is left
blank, SheepShaver expects the ROM file to be called "ROM" and be in the same directory as
the SheepShaver application.
