Some features of Basilisk II: |
| 32 |
|
- Emulates either a Mac Classic (which runs MacOS 0.x thru 7.5) |
| 285 |
|
application via Alt-Tab, Basilisk II is put in "snooze" mode (i.e. MacOS |
| 286 |
|
is frozen). |

Mac OS X: |
| 289 |
|
The "video mode" is one of the following: |
| 290 |
|
win/<width>/<height> |
| 291 |
|
win/<width>/<height>/<bits per pixel> |
| 292 |
< |
A refreshed (and buffered) [and very slow] Quartz window. |
| 294 |
< |
The default <bits> is 32, which is the only depth currently supported. |
| 292 |
> |
A refreshed (and buffered) Quartz window. |
| 293 |
|
full/<width>/<height> |
| 294 |
|
full/<width>/<height>/<bits per pixel> |
| 295 |
|
A CGDirectDisplay full screen mode. <bits> can currently be 8, 16 or 32. |
| 296 |
|
If not specified, the default is 32. There is currently no way to switch |
| 297 |
|
between the Mac OS X and Basilisk II display, but Apple-Option-Escape |
| 298 |
|
instantly and safely terminates the Basilisk II program. |

Currently unimplemented, will be a fast windowed mode. |

The "ethernet card description" is the name of an Ethernet interface. |

| 365 |
> |
There are four approaches to networking with Basilisk II: |
| 366 |
|
|
| 367 |
|
1. Direct access to an Ethernet card via the "sheep_net" kernel module. |
| 368 |
|
The "ethernet card description" must be the name of a real Ethernet |
| 432 |
|
your network administrator about the nets and zones you can use |
| 433 |
|
(instead of the ones given in the example above). |
| 434 |
|
|
| 435 |
+ |
3. Access the network through a "tuntap" interface. |
| 436 |
+ |
The "ethernet card description" must be set to "tun". |
| 437 |
+ |
|
| 438 |
+ |
TUN/TAP provides packet reception and transmission for user |
| 439 |
+ |
space programs. It can be viewed as a simple Point-to-Point |
| 440 |
+ |
or Ethernet device, which instead of receiving packets from a |
| 441 |
+ |
physical media, receives them from user space program and |
| 442 |
+ |
instead of sending packets via physical media writes them to |
| 443 |
+ |
the user space program. |
| 444 |
+ |
|
| 445 |
+ |
Prerequesties: |
| 446 |
+ |
- Make sure the "tun" kernel module is loaded |
| 447 |
+ |
# modprobe tun |
| 448 |
+ |
- Make sure IP Fordwarding is enabled on your system |
| 449 |
+ |
# echo 1 >/proc/sys/net/ipv4/ip_forward |
| 450 |
+ |
|
| 451 |
+ |
A virtual network configuration script is required and the |
| 452 |
+ |
default is /usr/local/BasiliskII/tunconfig unless you specify |
| 453 |
+ |
a different file with the "etherconfig" item. |
| 454 |
+ |
|
| 455 |
+ |
This script requires you that "sudo" is properly configured |
| 456 |
+ |
so that "/sbin/ifconfig" and "/sbin/iptables" can be executed |
| 457 |
+ |
as root. Otherwise, you can still write a helper script which |
| 458 |
+ |
invokes your favorite program to enhance a user priviledges. |
| 459 |
+ |
e.g. in a KDE environment, kdesu can be used as follows: |
| 460 |
+ |
|
| 461 |
+ |
#!/bin/sh |
| 462 |
+ |
exec /usr/bin/kdesu -c /path/to/tunconfig $1 $2 |
| 463 |
+ |
|
| 464 |
+ |
4. Access the network through the user mode network stack. |
| 465 |
+ |
(the code and this documentation come from QEMU) |
| 466 |
+ |
|
| 467 |
+ |
By setting the "ethernet card description" to "slirp", |
| 468 |
+ |
Basilisk II uses a completely user mode network stack (you |
| 469 |
+ |
don't need root priviledges to use the virtual network). The |
| 470 |
+ |
virtual network configuration is the following: |
| 471 |
+ |
|
| 472 |
+ |
Basilisk II <------> Firewall/DHCP server <-----> Internet |
| 473 |
+ |
(10.0.2.x) | (10.0.2.2) |
| 474 |
+ |
| |
| 475 |
+ |
----> DNS server (10.0.2.3) |
| 476 |
+ |
| |
| 477 |
+ |
----> SMB server (10.0.2.4) |
| 478 |
+ |
|
| 479 |
+ |
Basilisk II behaves as if it was behind a firewall which |
| 480 |
+ |
blocks all incoming connections. You can use a DHCP client to |
| 481 |
+ |
automatically configure the network in Basilisk II. |
| 482 |
+ |
|
| 483 |
+ |
In order to check that the user mode network is working, you |
| 484 |
+ |
can ping the address 10.0.2.2 and verify that you got an |
| 485 |
+ |
address in the range 10.0.2.x from the Basilisk II virtual |
| 486 |
+ |
DHCP server. |
| 487 |
+ |
|
| 488 |
+ |
Note that ping is not supported reliably to the internet as |
| 489 |
+ |
it would require root priviledges. It means you can only ping |
| 490 |
+ |
the local router (10.0.2.2). |
| 491 |
+ |
|
| 492 |
+ |
When using the built-in TFTP server, the router is also the |
| 493 |
+ |
TFTP server. |
| 494 |
+ |
|
| 495 |
|
FreeBSD: |
| 496 |
|
The "ethertap" method described above also works under FreeBSD, but since |
| 497 |
|
no-one has found the time to write a section for this manual, you're on |
| 584 |
|
error alerts. All errors will then be reported to stdout. The default |
| 585 |
|
is "false". |
| 586 |
|
|
| 587 |
+ |
keyboardtype <keyboard-id> |
| 588 |
+ |
|
| 589 |
+ |
Specifies the keyboard type that BasiliskII should report to the MacOS. |
| 590 |
+ |
The default is "5" which is a "Apple Extended Keyboard II (ISO)", |
| 591 |
+ |
but many other numbers are understood by most versions of the MacOS |
| 592 |
+ |
(e.g. 11 is a "Macintosh Plus Keyboard with keypad", |
| 593 |
+ |
13 is a "Apple PowerBook Keyboard (ISO)" ) |
| 594 |

| 596 |
|
|
| 597 |
|
|
| 640 |
|
|
| 641 |
|
Set this to "true" to ignore illegal memory accesses. The default |
| 642 |
|
is "false". This feature is only implemented on the following |
| 643 |
< |
platforms: Linux/x86, Linux/ppc. |

platforms: Linux/x86, Linux/ppc, Darwin/ppc. |

dsp <device name> |
| 646 |
> |
mixer <device name> |
| 647 |
> |
|
| 648 |
> |
Under Linux and FreeBSD, this specifies the devices to be used for sound |
| 649 |
> |
output and volume control, respectively. The defaults are "/dev/dsp" and |
| 650 |
> |
"/dev/mixer". |

JIT-specific configuration |
| 750 |
+ |
-------------------------- |
| 751 |
+ |
|
| 752 |
+ |
A Just-In-Time (JIT) translation engine is available for x86. This is |
| 753 |
+ |
aimed at translating 68040 instructions to native equivalent code |
| 754 |
+ |
sequences, thus providing faster emulation speeds. |
| 755 |
+ |
|
| 756 |
+ |
jit <"true" or "false"> |
| 757 |
+ |
|
| 758 |
+ |
Set this to "true" to enable the JIT compiler. Default value is |
| 759 |
+ |
"true" if the JIT compiler was compiled in. Besides, this is |
| 760 |
+ |
effective only if Basilisk II is configured to emulate a 68040. |
| 761 |
+ |
|
| 762 |
+ |
jitfpu <"true" or "false"> |
| 763 |
+ |
|
| 764 |
+ |
Set this to "true" to enable translation of floating-point (FPU) |
| 765 |
+ |
instructions. Default is "true". |
| 766 |
+ |
|
| 767 |
+ |
jitcachesize <size> |
| 768 |
+ |
|
| 769 |
+ |
Allocate "size" kilobytes of RAM for the translation cache. The |
| 770 |
+ |
value given will be rounded down to the nearest multiple of a page |
| 771 |
+ |
size. Minimal value is "2048" (2MB). Default value is "8192" (8MB). |
| 772 |
+ |
|
| 773 |
+ |
jitlazyflush <"true" or "false"> |
| 774 |
+ |
|
| 775 |
+ |
Set this to "true" to enable lazy invalidation of the translation |
| 776 |
+ |
cache. This is always recommended as it usually makes the system |
| 777 |
+ |
more responsive and faster, especially while running MacOS |
| 778 |
+ |
8.X. Default value is "true". |
| 779 |
+ |
|
| 780 |
+ |
jitdebug <"true" or "false"> |
| 781 |
+ |
|
| 782 |
+ |
Set this to "true" to enable the JIT debugger. This requires a |
| 783 |
+ |
build of Basilisk II with the cxmon debugger. Default is "false". |
