Additions, corrections and constructive criticism are invited. In particular, information on system quirks is more than welcome. This document tries to provide a starting point for those who want to run &os; on an &arch.print;-based machine. It is aimed at providing background information on the various hardware designs. It is not a replacement for the systems manuals. The information is structured as follows: General hardware requirements to run &os; on &arch;. System specific information for each of the systems/boards supported by &os;. Information on expansion boards for &os;, including things that differ from what is in the generic supported hardware list. &os;/&arch; requires an &arch.print; system. Currently, the newer PCI-based systems are supported better than the older SBus based systems. The following systems are known to work to varying degrees: Sun Ultra 1 workstations Sun Ultra 2 workstations Sun Ultra 5 workstations Sun Ultra 10 workstations Sun Ultra 30 workstations Sun Ultra 60 workstations Sun Blade 100 workstations Sun Netra t1 series servers Sun Enterprise 220R servers Sun Enterprise 250 servers Sun Enterprise 420R servers Ultra 80 and Blade 1000 are expected to work, maybe with minor modifications. SMP is supported on Ultra 2 and 60 workstations and Enterprise 220R, 250 and 420R servers. Below is an overview of the &arch.print; hardware that &os; runs on. The GENERIC kernel configuration file in /sys/&arch;/conf/GENERIC may contain additional information about supported devices. UltraSPARC Ultra1-family systems have not been thoroughly tested with FreeBSD. These systems are not very well supported, but it is possible to install FreeBSD onto an Ultra-1e with a hme Ethernet interface. UltraSPARC Ultra2-family systems include the following hardware: 1 or 2 UltraSPARC II CPUs Built-in Ethernet (hme compatible) interface 4 SBus slots 1 UPA Slot Serial and Parallel ports 16-bit audio UltraSPARC Ultra5/10-family systems include the following hardware: UltraSPARC IIi CPU Three PCI busses Built-in Ethernet (hme compatible) interface Built-in PCI-IDE controller &perforce; Two PC-AT style `com' ports for the mouse and keyboard Floppy driver controller Siemens SAB82532 dual-channel serial ports for ttya and ttyb One CS4231 audio device One PC-AT style parallel port Sun `ffb' frame buffer (Ultra10 only) EBus (Sun proprietary bus for slow devices) Sun Ultra 60 workstations include the following hardware: 1 or 2 UltraSPARC II CPUs 4 PCI slots 2 UPA slots &man.sym.4;-based UltraSCSI controller Built-in Ethernet (hme compatible) interface Serial and Parallel ports 16-bit audio EBus (Sun proprietary bus for slow devices) Sun Blade 100 workstations include the following hardware: UltraSPARC IIe CPU Three PCI busses Built-in Ethernet (gem compatible) interface Two USB ports &unsupported; Two Firewire ports &unsupported; Built-in PCI-IDE controller &perforce; Two PC-AT style `com' ports for the mouse and keyboard Floppy driver controller &man.sio.4; supported serial ports for ttya and ttyb One CS4231 audio device One PC-AT style parallel port Built-in PGX64 (ATI) graphics EBus (Sun proprietary bus for slow devices) ISA bus A word of caution: the installed base for &os;/&arch; is not nearly as large as for &os;/Intel. This means that the enormous variation of PCI/ISA expansion cards out there has much less chance of having been tested on &arch; than on Intel. This is not to imply they are doomed to fail, just that the chance of running into something never tested before is much higher. GENERIC contains things that are known to work on &arch; only. The PCI bus is fully supported. SBus support is limited, but is reported to work well enough to netboot an SBus-based Ultra 2 workstation. 1.44 Mbyte floppy drives are not yet supported. ATA and ATAPI (IDE) devices are supported via the &man.ata.4; driver framework. &perforce; There is full SCSI support via the CAM layer. However, only NCR/Symbios cards are currently working. Adaptec 2940x (AIC 7xxx chip-based) and &man.isp.4; cards should be supported soon. Be aware that SCSI cards must contain Sun FCODE in order to use them as a boot device from OpenBoot. If you want to boot your sparc64 over the Ethernet you will obviously need an Ethernet card that the OpenBoot console recognizes. hme, gem, and eri based network devices. The PC standard serial ports found on most newer Sun workstations are supported.
