1.11 briggs 63: The mac68k port of OpenBSD was derived from NetBSD/mac68k, and it

68: Active building and testing of OpenBSD/mac68k was discontinued after

1.87 miod 70: </p>
1.42 miod 71:
72: <p>
1.87 miod 73: Eventually the lack of a proper firmware interface, requiring the use of a
74: MacOS application as the bootloader, with little or no possibility of updating
75: this application to match progress in OpenBSD (let alone rebuild it with a
76: free software toolchain) convinced the developers to give up supporting this
77: port, and remove the code from the tree.

87: <p>
1.87 miod 88: OpenBSD/mac68k used to run on a large part of the 680x0-based Macintosh
1.42 miod 89: computers.
1.87 miod 90: The kernel itself had support for the following processor combinations:
1.15 johns 91: <ul>
1.42 miod 92: <li>68020 with 68851 PMMU and 68881 FPU
93: <li>68030 with 68882 FPU
94: <li>68040 (<b>not</b> including the 68LC040)
1.15 johns 95: </ul>
96:
97: <p>
1.87 miod 98: The following Macintosh models used to be supported and tested.
1.62 martin 99: This means that at least the SCSI controller, serial console and on-board
1.87 miod 100: ethernet would function on these models.
101: On some of these machines, a full 68040 CPU was required to replace the
1.62 martin 102: default 68LC040 CPU.
