NetBSD/amd64 is a port to the AMD64 family of processors and supports all other CPUs that implement the 64bit AMD64 architecture. These currently include AMD Opteron, AMD Athlon64, and Intel CPUs with the EM64T extension. NetBSD/amd64 is a true 64bit operating system. Running 32bit NetBSD/i386 binaries is supported as well, see &man.compat.netbsd32.8;. Running 32bit Linux emulations will be available in the future, the setup will be similar to the one described in &man.compat.svr4.32.8;. The port was first committed to the NetBSD source tree as NetBSD/x86_64 on June 19th, 2001 and renamed to NetBSD/amd64 on April 26th, 2003. The original work to do this port was done by Frank van der Linden at Wasabi Systems, assisted by AMD, who provided the simulator (Simics VirtuHammer), pre-release hardware and access to a range of Opteron hardware through the AMD Developer Center. The port is fully functional. It has been tested on single-CPU and multiprocessor (SMP) Opteron configurations. Since the release of NetBSD 2.0, it is a completely supported platform. NetBSD's port to the AMD64 architecture Virtutech Simics simulator X86-64.org Thanks to the work of Mihai Chelaru, a driver for the Abit uGuru Hardware system monitor was committed in -current. Abit uGuru is a hardware chip in the Abit(TM) motherboards to monitor and control the system including fans, temperatures and voltages. For now the ug(4) driver only can show the values on these sensors. A pullup has been sent for netbsd-4, so it will appear in the next major NetBSD version. More information about uGuru can be seen at: Abit's uGuru page. &a.jschauma; has uploaded binary packages for NetBSD-3.0/amd64 from the pkgsrc-2006Q2 branch into . &a.jschauma; has uploaded binary packages for NetBSD-2.0/amd64 from the pkgsrc-2005Q1 branch into . Frank van der Linden announced that the NetBSD/amd64 Port is now completely crossbuildable. Please see his message to the port-amd64 Mailing List for details. The most recent snapshot, based on 2003-05-10 sources is now available as a bootable ISO install image, located at the NetBSD/amd64 snapshot area of the ftp server. This snapshot has some important improvements in it. For details, look at the README file. The mailing list, port-x86_64, has been renamed to port-amd64.
