OpenBSD 5.0 is a new version of a BSD-based operating system renown for its high security. Some of the new features and systems in the new release include: Improved hardware support, including: MSI interrupts for many devices, on those architectures which can support them (amd64, i386, sparc64 only so far); a new dma_alloc(9) API makes it easier for kernel code to allocate dma-safe memory; as a result, big-memory support has been enabled on all possible architectures; the rather rare bce(4) driver now copies mbufs all the time, to cope with the hardware having a 1 GB limit. Highlights: GNOME 2.32.2, KDE 3.5.10, Mozilla Firefox 3.5.19, 3.6.18 and 5.0, LibreOffice 3.4.1, PHP 5.2.17 and 5.3.6, Chromium 12.0.742.122.
The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX. OpenBSD is freely available from our FTP sites, and also available in an inexpensive 3-CD set.
