<H1>Using SheepShaver</H1>
|
||
|
|
|
||
|
|
<H2>Changing the display mode</H2>
|
||
|
|
|
||
|
|
SheepShaver can display the MacOS user interface in an X11 window or full-screen
|
||
|
|
(much faster). 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).
|
||
|
|
|
||
|
|
<H2>Full-screen mode</H2>
|
||
|
|
|
||
|
|
The full-screen mode uses the whole X11 screen for displaying the MacOS user interface.
|
||
|
|
You can temporarily switch back to the X11 desktop by pressing Ctrl-Tab. The MacOS (and
|
||
|
|
all MacOS applications) will now be suspended. You can resume SheepShaver by activating
|
||
|
|
the "SheepShaver suspended" window and pressing the space key. Using full-screen mode
|
||
|
|
requires a DGA capable X server.
|
||
|
|
|
||
|
|
<H2>Networking</H2>
|
||
|
|
|
||
|
|
There are three approaches to networking with SheepShaver:
|
||
|
|
|
||
|
|
<OL>
|
||
|
|
<LI>Direct access to an Ethernet card via the "sheep_net" driver.
|
||
|
|
In this case, the "ethernet card description" must be the name
|
||
|
|
of a real Ethernet card, e.g. "eth0". It also requires the "sheep_net"
|
||
|
|
driver to be installed and accessible. This approach will allow you
|
||
|
|
to run all networking protocols under MacOS (TCP/IP, AppleTalk, IPX
|
||
|
|
etc.) but there is no connection between Linux networking and MacOS
|
||
|
|
networking. MacOS will only be able to talk to other machines on
|
||
|
|
the Ethernet, but not to other networks that your Linux box routes
|
||
|
|
(e.g. a second Ethernet or a PPP connection to the Internet).
|
||
|
|
|
||
|
|
<LI>Putting SheepShaver on a virtual Ethernet via the "ethertap" device.
|
||
|
|
In this case, the "ethernet card description" must be the name
|
||
|
|
of an ethertap interface, e.g. "tap0". It also requires that you
|
||
|
|
configure your kernel to enable routing and the ethertap device:
|
||
|
|
under "Networking options", enable "Kernel/User netlink socket" and
|
||
|
|
"Netlink device emulation", under "Network device support", activate
|
||
|
|
"Ethertap network tap". You also have to modify <CODE>devices/net/ethertap.c</CODE>
|
||
|
|
a bit before compiling the new kernel:
|
||
|
|
|
||
|
|
<UL>
|
||
|
|
<LI>insert <CODE>#define CONFIG_ETHERTAP_MC 1</CODE> near the top (after the <CODE>#include</CODE> lines)
|
||
|
|
<LI>comment out the line <CODE>dev->flags|=IFF_NOARP;</CODE> in <CODE>ethertap_probe()</CODE>
|
||
|
|
</UL>
|
||
|
|
|
||
|
|
<P>
|
||
|
|
Next, see <CODE>/usr/src/linux/Documentation/networking/ethertap.txt</CODE> for
|
||
|
|
information on how to set up <CODE>/dev/tap*</CODE> device nodes and activate the
|
||
|
|
ethertap interface. Under MacOS, select an IP address that is on the
|
||
|
|
virtual network and set the default gateway to the IP address of the
|
||
|
|
ethertap interface. This approach will let you access all networks
|
||
|
|
that your Linux box has access to (especially, if your Linux box has
|
||
|
|
a dial-up Internet connection and is configured for IP masquerading,
|
||
|
|
you can access the Internet from MacOS). The drawback is that you
|
||
|
|
can only use network protocols that Linux can route, so you have to
|
||
|
|
install and configure netatalk if you want to use AppleTalk. Here is
|
||
|
|
an example <CODE>/etc/atalk/atalkd.conf</CODE> for a LAN:
|
||
|
|
|
||
|
|
<PRE>
|
||
|
|
eth0 -seed -phase 2 -net 1 -addr 1.47 -zone "Ethernet"
|
||
|
|
tap0 -seed -phase 2 -net 2 -addr 2.47 -zone "Sheepnet"
|
||
|
|
</PRE>
|
||
|
|
|
||
|
|
(the "47" is an arbitrary node number). This will set up a zone
|
||
|
|
"Ethernet" (net 1) for the Ethernet and a zone "Sheepnet" (net 2)
|
||
|
|
for the internal network connection of the ethertap interface.
|
||
|
|
MacOS should automatically recognize the nets and zones upon startup.
|
||
|
|
If you are in an existing AppleTalk network, you should contact
|
||
|
|
your network administrator about the nets and zones you can use
|
||
|
|
(instead of the ones given in the example above).
|
||
|
|
|
||
|
|
<LI>Networking protocols for serial connections (PPP and SLIP, for example)
|
||
|
|
can be used provided that you have the appropriate MacOS system components
|
||
|
|
installed (e.g. Open Transport/PPP).
|
||
|
|
</OL>
|
||
|
|
|
||
|
|
<H2>Using floppy disks</H2>
|
||
|
|
|
||
|
|
Floppy disks are not automatically detected when they are inserted. They have to be
|
||
|
|
mounted explicitly: after inserting a floppy disk, press Ctrl-F1.
|
||
|
|
|
||
|
|
<H2>Accessing Linux files</H2>
|
||
|
|
|
||
|
|
SheepShaver will display a "Linux" disk icon on the Mac desktop that allows you
|
||
|
|
to access any Linux files which are in the directory specified as "Linux Root"
|
||
|
|
in the "Volumes" pane of the SheepShaver settings. You can open and save files on the
|
||
|
|
"Linux" disk from Mac applications, copy, move or rename files from the Finder etc.
|
||
|
|
SheepShaver translates some file name extensions to MacOS types and vice versa,
|
||
|
|
so e.g. *.jpg and *.pdf files will show the correct icons in the Finder. MacOS
|
||
|
|
resources and Finder attributes are stored in hidden <CODE>.rsrc</CODE> and
|
||
|
|
<CODE>.finf</CODE> directories.
|
||
|
|
|
||
|
|
<H2>Copying text via the clipboard</H2>
|
||
|
|
|
||
|
|
SheepShaver tries to keep the Linux and MacOS clipboards synchronized. That means,
|
||
|
|
when you copy a piece of text under Linux, you can paste it into a MacOS application
|
||
|
|
and vice versa.
