Overview |

|
-------- |

|
|
| 18 |
< |
Basilisk II is a free, portable, Open Source 68k Mac emulator. It requires |
| 19 |
< |
a copy of a Mac ROM and a copy of MacOS to run. Basilisk II is freeware and |
| 20 |
< |
distributed under the GNU General Public License. |
| 18 |

Basilisk II is an Open Source 68k Macintosh emulator. That is, it enables |
| 19 |
> |
you to run 68k MacOS software on you computer, even if you are using a |
| 20 |
> |
different operating system. However, you still need a copy of MacOS and |
| 21 |
> |
a Macintosh ROM image to use Basilisk II. |
| 22 |
|
|
| 23 |
|
Basilisk II has currently been ported to the following systems: |
| 24 |
|
- BeOS R4 (PowerPC and x86) |
| 25 |
< |
- Unix (tested under Linux, Solaris 2.5, FreeBSD 3.x and IRIX 6.5) |

> |
- Unix (tested under Linux, Solaris 2.5, FreeBSD 3.x, NetBSD 1.4.2 and |
| 26 |
> |
IRIX 6.5) |
| 27 |
|
- AmigaOS 3.x |
| 28 |
|
- Windows NT 4.0 (mostly works under Windows 95/98, too) |
| 29 |
|
|
| 36 |
|
- Floppy disk driver (only 1.44MB disks supported) |
| 37 |
|
- Driver for HFS partitions and hardfiles |
| 38 |
|
- CD-ROM driver with basic audio functions |
| 39 |
+ |
- Easy file exchange with the host OS via a "Host Directory Tree" icon |
| 40 |
+ |
on the Mac desktop |
| 41 |
|
- Ethernet driver |
| 42 |
|
- Serial drivers |
| 43 |
|
- SCSI Manager (old-style) emulation |
| 44 |
|
- Emulates extended ADB keyboard and 3-button mouse |
| 45 |
< |
- Uses UAE 68k emulation or (under AmigaOS) real 68k processor |

is the same as that of "disk" lines. |

extfs <direcory path> |

This item specifies the root directory for the "Host Directory Tree" |
| 147 |
+ |
file system (the "Unix/BeOS/Amiga/..." icon on the Finder desktop). |
| 148 |
+ |
All objects contained in that directory are accessible by Mac applications. |
| 149 |
+ |
This feature is only available when File System Manager V1.2 or later |
| 150 |
+ |
is installed on the Mac side. FSM 1.2 is built-in beginning with MacOS 7.6 |
| 151 |
+ |
and can be installed as a system extension (downloadable from Apple, look |
| 152 |
+ |
for the FSM SDK in the developer section) for earlier MacOS versions. |

"width" and "height" specify the maximum width/height to use. |
| 219 |
< |
Saying "dga/0/0" means "complete screen". For DGA to work, Basilisk II |
| 220 |

must be compiled with DGA support enabled (selectable in the configure |

script). |

The "frame buffer name" is looked up in the "fbdevices" file (whose |

path can be specified with the "fbdevicefile" prefs item) to determine |

certain characteristics of the device (doing a "ls -l /dev/fb" should |

The "video mode" is one of the following: |
| 236 |
|
15-bit truecolor display in a Picasso96 PIP. This requires |
| 237 |
|
Picasso96 as well as a PIP-capable graphics card (e.g. Picasso IV). |
| 238 |

scr/<hexadecimal mode ID> |
| 239 |
< |
8/15/24-bit fullscreen display on a Picasso96 screen with the given |
| 240 |
< |
mode ID. This requires Picasso96. For 15 and 24 bit, the frame buffer |
| 241 |
< |
format must be QuickDraw-compatible (big-endian, xRGB 1:5:5:5 or |
| 242 |
< |
xRGB 8:8:8:8). The screen size will be the default size for that |
| 243 |
< |
mode ID. |

The "video mode" is one of the following: |
| 327 |
|
BeOS: |
| 328 |
|
It doesn't matter what you give as "ethernet card description", Basilisk II |
| 329 |
|
will always use the first Ethernet card it finds as long an an "ether" |
| 330 |
< |
line exists (e.g. say "ether yes"). As Basilisk II requires the sheep_net |
| 331 |
< |
net server add-on from SheepShaver, you can only use Ethernet on PowerPC |
| 332 |
< |
machines. |
| 330 |

line exists (e.g. say "ether yes"). Using Ethernet requires the "sheep_net" |
| 331 |

Net Server add-on to be installed. The first time you start Basilisk II |
| 332 |
> |
with Ethernet enabled you will be asked whether it's OK to make the |
| 333 |
> |
necessary changes to your BeOS network configuration to enable sheep_net. |
| 334 |
|
|
| 335 |
|
Linux: |
| 336 |
|
The "ethernet card description" is the name of an Ethernet interface. |
| 337 |
|
There are two approaches to networking with Basilisk II: |
| 338 |
+ |
|
| 339 |
|
1. Direct access to an Ethernet card via the "sheep_net" driver. |
| 340 |
|
In this case, the "ethernet card description" must be the name |
| 341 |
|
of a real Ethernet card, e.g. "eth0". It also requires the "sheep_net" |
| 345 |
|
networking. MacOS will only be able to talk to other machines on |
| 346 |
|
the Ethernet, but not to other networks that your Linux box routes |
| 347 |
|
(e.g. a second Ethernet or a PPP connection to the Internet). |
| 348 |
+ |
|
| 349 |
|
2. Putting Basilisk II on a virtual Ethernet via the "ethertap" device. |
| 350 |
|
In this case, the "ethernet card description" must be the name |
| 351 |
|
of an ethertap interface, e.g. "tap0". It also requires that you |
| 352 |
|
configure your kernel to enable routing and the ethertap device: |
| 353 |
|
under "Networking options", enable "Kernel/User netlink socket" and |
| 354 |
|
"Netlink device emulation", under "Network device support", activate |
| 355 |
< |
"Ethertap network tap". Next, see /usr/src/linux/Documentation/ |
| 356 |
< |
networking/ethertap.txt for information on how to set up /dev/tap* |
| 357 |
< |
device nodes and activate the ethertap interface. Under MacOS, |
| 358 |
< |
select an IP address that is on the virtual network and set the |
| 359 |
< |
default gateway to the IP address of the ethertap interface. This |
| 360 |
< |
approach will let you access all networks that your Linux box has |
| 361 |
< |
access to (especially, if your Linux box has a dial-up Internet |
| 362 |
< |
connection and is configured for IP masquerading, you can access |
| 363 |
< |
the Internet from MacOS). The drawback is that you can only use |
| 364 |
< |
network protocols that Linux can route, so you have to install and |
| 365 |
< |
configure netatalk if you want to use AppleTalk. |
| 355 |
> |
"Ethertap network tap". You also have to modify drivers/net/ethertap.c |
| 356 |
> |
a bit before compiling the new kernel: |
| 357 |
> |
|
| 358 |
> |
- insert "#define CONFIG_ETHERTAP_MC 1" near the top (after the |
| 359 |
> |
#include lines) |
| 360 |
> |
- comment out the line "dev->flags|=IFF_NOARP;" in ethertap_probe() |
| 361 |

|

an example /etc/atalk/atalkd.conf for a LAN: |

|
| 374 |

eth0 -seed -phase 2 -net 1 -addr 1.47 -zone "Ethernet" |
| 375 |
> |
tap0 -seed -phase 2 -net 2 -addr 2.47 -zone "Basilisknet" |
| 376 |
> |
|
| 377 |
> |
(the "47" is an arbitrary node number). This will set up a zone |
| 378 |
> |
"Ethernet" (net 1) for the Ethernet and a zone "Basilisknet" (net 2) |
| 379 |
> |
for the internal network connection of the ethertap interface. |
| 380 |
> |
MacOS should automatically recognize the nets and zones upon startup. |
| 381 |
> |
If you are in an existing AppleTalk network, you should contact |
| 382 |
> |
your network administrator about the nets and zones you can use |
| 383 |

(instead of the ones given in the example above). |

You have to specify the name of the SANA-II Ethernet device and the device |
| 422 |
|
For refreshed graphics modes (usually window modes), this specifies |
| 423 |
|
how many frames to skip after drawing one frame. Higher values make |
| 424 |
|
the video display more responsive but require more processing power. |
| 425 |

The default is "8". |

The default is "8". Under Unix/X11, a value of "0" selects a "dynamic" |

By default, the X11 event handler in Basilisk II uses KeySyms to |
| 469 |
|
translate keyboard event to Mac keycodes. While this method is very |
| 474 |
|
not on the selected keymap. Unfortunately it depends on the X server |
| 475 |
|
being used and possibly also on the type of keyboard attached. So |
| 476 |
|
Basilisk II needs a table to translate X keycodes to Mac keycodes. |
| 477 |
< |
This table is read by default from /usr/local/lib/basilisk_ii_keycodes |
| 477 |

This table is read by default from /usr/local/share/BasiliskII/keycodes |

This item controls the type of memory to use for SCSI buffers. Possible |
| 514 |

values are: |
| 515 |
+ |
0 Chip memory |

2 Any memory |
| 518 |
+ |
|
| 519 |

Be warned that many SCSI host adapters will not work with the "Any memory" |
| 520 |
+ |
setting. Basilisk II has no way of knowing which memory type is supported |
| 521 |
+ |
by the host adapter and setting an unsupported type will result in data |
| 522 |
+ |
corruption. |
