NetBSD
NetBSD/i386 PS/2 and MCA Bus Support

From 1996 to 1999 I worked sporadically on adding support for MicroChannel (MCA)-based IBM PS/2 systems to the NetBSD/i386 kernel, releasing patches for NetBSD 1.1, 1.2 and 1.3.3.

Jaromir Dolecek took over this work in 2000 and updated and integrated my code into NetBSD-current (as of 1.4Y or thereabouts) with Greg McGarry's IBM MCA Token Ring driver included. NetBSD 1.5 was the first official release with PS/2 and MCA support included.

See the NetBSD/i386 on IBM PS/2 page on the NetBSD website or my old NetBSD 1.3.3 PS/2 patches page (historic interest only) for more information.
