23: OpenBSD/solbourne is an experimental port of OpenBSD to the Solbourne ``IDT''
24: family of workstations, built upon the sparc-compatible Panasonic <i>KAP</i>
25: processor.
26:
27: <p>
28: The current port maintainer is Miod Vallat
29: (<a href="mailto:miod@openbsd.org">miod@openbsd.org</a>).
30: Others are definitely welcome to contribute!

46:
47: <p>
48: The KAP processor used in the IDT systems, albeit using an instruction
49: set similar to the sparc processors, uses a completely different MMU.
50: Because of this, no free operating system considered running on these Solbourne
51: machines more than a few minutes...
52:
53: <p>
54: At some point, an S4000 was donated by Mike Nicewonger to Miod Vallat, who then
55: had no excuse not to work on a port.
56: After a few years of procrastination, real work on a port eventually started in
57: march 2005, leading to an initial import in the OpenBSD tree exactly one month
58: later. And work continues...

65: Currently, only the S4000 system has been tested; but other systems should work,
66: although the L2 cache in the S4000DX systems is not supported yet.
67:
68: <p>
69: Right now, the system boots single-user, but userland has issues, which are
70: being worked on.
