OpenBSD mac68k

History:

The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it used to support most of the same hardware as NetBSD.

Active building and testing of OpenBSD/mac68k was discontinued after OpenBSD 4.6 due to lack of interest with developers and builder.

Eventually the lack of a proper firmware interface, requiring the use of a MacOS application as the bootloader, with little or no possibility of updating this application to match progress in OpenBSD (let alone rebuild it with a free software toolchain) convinced the developers to give up supporting this port, and remove the code from the tree.

Supported models

OpenBSD/mac68k used to run on a large part of the 680x0-based Macintosh computers. The kernel itself had support for the following processor combinations:

• 68020 with 68851 PMMU and 68881 FPU
• 68030 with 68882 FPU
• 68040 (not including the 68LC040)

The following Macintosh models used to be supported and tested. This means that at least the SCSI controller, serial console and on-board ethernet would function on these models. On some of these machines, a full 68040 CPU was required to replace the default 68LC040 CPU.

• Classic family: SE30
• LC family: LC, LC II, LC III, LC III+, LC475, Performa 400-430, Performa 450, Performa 460, Performa 475, Performa 476
• Centris family: 610, 650
• Quadra family: 605, 610, 630, 650, 660AV, 700, 800, 840AV, 900, 950

Supported devices

• Internal SCSI controllers and peripherals:
  • Quadra/Centris series' onboard NCR 53c96 SCSI controller (esp).
  • Macintosh II-series', Performa, and LC-series' onboard NCR 5380 SCSI controller (ncrscsi, sbc).
  • SCSI disk drives (sd).
  • SCSI cdrom drives (cd).
  • Autochangers (ch).
  • Tape drives (st).
• Internal sound (asc).
• NuBus internal expansion bus (nubus).
• Internal video and most NuBus video cards (macfb).
• Both internal serial ports (zsc).
• ADB keyboards and mice (adb) (except on the IIfx, Quadra 900 and 950).
• Ethernet cards based on the Natl. Semiconductor 8390 (Asante, Apple, and a few others) (ae).
• Quadra/Centris AV series' onboard MACE ethernet (mc).
• Some ethernet cards based on the SONIC chip including internal Ethernet on many of Apple's non-AV Quadras/Centrises (sn).

Untested systems

The following Macintosh models used to be untested, and/or lacked support for major subsystems.

• Classic family: Color Classic, Classic II
• Macintosh II family: Mac II, IIx, IIcx, IIci, IIsi, IIfx, IIvi, IIvx, Performa 600
• 500 family: 520, 550, 575, 580, Mac TV

Unsupported systems

• PowerPC-based Macs. Some of these are supported in the OpenBSD/macppc port.
• Powerbook family. Hardware capabilities limit the usability of these systems.
• Machines based on the 68LC040 processor. Unfortunately, the chip itself contains a major bug for which there is no software workaround available in OpenBSD.

Unsupported devices

• Apple Communication Slot (CS) ethernet cards.
• Any other NuBus card not listed above.
• Floppy drive.
• IOP ADB subsystem on the IIfx, Quadra 900 and 950.
• IDE drives.

Getting and installing OpenBSD/mac68k:

The last supported OpenBSD/mac68k release was OpenBSD 5.1. ¡®Yes, sir. I felt sure you understood that. She said she had told you.¡¯ "Why, eh,--I--I don't know that my movements need have anything to do with his. Yours, of course,--" "Ah, but if it saved your life!" "No, I'm not," grumbled the Doctor, "I've had enough of this wild-goose chase. And besides, it's nearly dinner time." "I am coming to that," Lawrence said, lighting a fresh cigarette. "As soon as Bruce was in trouble and the plot began to reel off I saw that it was mine. Of course there were large varyings in the details, but the scheme was mine. It was even laid on the same spot as my skeleton story. When I grasped that, I knew quite well that somebody must have stolen my plot." Judy In a coach-house, through which we passed on our way to see the prince's favourite horses with the state carriages¡ªquite commonplace and comfortable, and made at Palitana¡ªwas a chigram,[Pg 68] off which its silk cover was lifted; it was painted bright red and spangled with twinkling copper nails. This carriage, which is hermetically closed when the Ranee goes out in it, was lined with cloth-of-gold patterned with Gohel Sheri's initials within a horseshoe: a little hand-glass on one of the cushions, two boxes of chased silver, the curtains and hangings redolent of otto of roses. "Are you certain of it? You have seen so very little of him, and you may be mistaken." "And your wife?" "I drawed on my man's bundle o' wood," said Gid, "and then dropped a little, so's to git him where he was biggest and make sure o' him." HoME²¨¶àÒ°½áÒÂ×óÏßÊÓƵ ENTER NUMBET 0016www.mellerio.com.cn
