FYI, HEAD now has basic support for sun4u-machines based on USIII and beyond. If you want to give it a try there's a install image snapshot (built with neither docs nor ports) available at: http://people.freebsd.org/~marius/8.0-20081011-SNAP-sparc64-disc1.iso.gz Known working machines so far are: Blade 1000, Blade 1500, Blade 2000, Fire V210, Fire 280R and Netra 20/Netra T4 though machines similar to these like Fire V240 probably will also just work with all essential on-board devices being supported. AFAICT stability is en par with that on USII-based machines (i.e. it crashed neither during lots of compilations nor heavy network load for me). Caveats: o Besides serial devices, only those supported by creator(4) are currently usable as console, i.e. not even machfb(4) works at this point (it'll trigger a RED state exception, which shouldn't be that hard to fix though), let alone XVR cards. o It's not clear whether all endian-bugs in mpt(4) (such controllers are found on-board in f.e. Fire V440) are fixed, yet. It works just fine with an SAS add-on card for me though. o There's no driver for the Sun Cassini/NS Saturn Gigabit NICs found on-board (again f.e. Fire V440) and as add-on cards so far. o There's no driver for controlling the fans in machines based on the Excalibur board, yet. This means that Blade 1000/2000 aren't very useable as workstations so far due to the noise caused by the fans permanently running at full speed. o There's no support for host-to-PCI-Express or host-to-PCI-X bridges so far due to lack of access to such machines (adding support for the XMITS PCI-X bridges to the existing schizo(4) should be rather straightforward, PCI-Express will require a new driver and probably some additional tweaking though).
