PC-BSD® hat moderate Hardwareanforderungen und häufig verbraucht es weniger Ressourcen als ihre kommerziellen Mitbewerber. Stellen Sie vor der Installation von PC-BSD® sicher, dass Ihre Hardware oder eine virtuellen Maschine wenigstens die Mindestanforderungen erfüllt. Um das Beste aus Ihrem PC-BSD® zu bekommen, sollten Sie die empfohlenen Systemanforderungen erfüllen.

Minimale Systemanforderungen

Als absolutes Minimum, muß Ihr System die folgenden Anforderungen erfüllen, um PC-BSD® installieren zu können:

  • 64-bit Prozessor
  • 1 GB RAM
  • 20 GB freien Festplattenspeicher auf der primären Partition bei einer TrueOS®-Serverinstallation
  • Netzwerkkarte

Empfohlene Systemanforderungen

Die folgenden empfohlenen Mindestanforderungen sollten erfüllt werden. Je mehr RAM und verfügbaren Festplattenspeicher, desto besser läuft Ihr System:

  • 64-Bit Prozessor
  • 4 GB RAM
  • 50 GB freien Festplattenspeicher auf der primären Partition bei einer Arbeitsplatzinstallation
  • Netzwerkkarte
  • Soundkarte
  • NVIDIA 3D beschleunigte Grafikkarte

Der Hardwaretest des PC-BSD Installers gibt eine Warnung aus, wenn die ausgewählte Partition bei einer Serverinstallation weniger als 20 GB bzw. bei einer Arbeitsplatzinstallation weniger als 50 GB freien Speicher zur Verfügung hat.

Man kann nie genug RAM im Rechner haben, daher installieren Sie so viel RAM wie Sie sich leisten können. Sie benöitgen eine schnelle CPU, um moderne Videospiele zu spielen können. Wenn Sie eine Sammlung von Songs und Filmen auf Ihrem Computer erstellen möchten, sollen Sie eine große Festplatte - die intern oder extern sein kann - vorsehen.

Unterstützte Prozessoren

PC-BSD® should install on any system containing a 64-bit (also called amd64) processor. Despite the amd64 name, a 64-bit processor does not need to be manufactured by AMD in order to be supported. The FreeBSD Hardware Notes[1] lists the amd64 processors known to work.

Unterstützte Grafikkarten

Like most open source operating systems, PC-BSD® uses X.org drivers for graphics support. PC-BSD® will automatically detect the optimal video settings for supported video drivers. You can verify that your graphics hardware is supported by clicking the Hardware-Kompatibilität icon within the installer.

Support for the major graphic vendors is as follows:

NVIDIA: if you want to use 3D acceleration, NVIDIA is currently the best supported as there is a native driver for PC-BSD®. If an NVIDIA video card is detected, an "nVidia settings" icon will be added to the Control Panel for managing NVIDIA settings.

Intel: 3D acceleration on most Intel graphics is supported. Due to the current KMS support, you will not be able to switch between the graphical console and a virtual console using Crtl+Alt+F#.

ATI/Radeon: 3D acceleration will not work on ATI or Radeon cards until FreeBSD completes its TTM work. You can still use these cards, but you will have to choose the 2D driver, and if that does not work, you will need to resort to using the Vesa driver.

Optimus: at this time Bumblebee[2] has not been ported to FreeBSD, meaning that there is no switching support between the two graphics adapters provided by Optimus. Optimus implementations vary, so PC-BSD® may or may not be able to successfully load a graphics driver on your hardware. If you get a blank screen after installation, check your BIOS to see if it has an option to disable one of the graphics adapters or to set “discrete” mode. If the BIOS does not provide a discrete mode, PC-BSD® will default to the 3D Intel driver and disable NVIDIA. This will change in the future when the NVIDIA driver supports Optimus.

WLAN-Karten

PC-BSD® has built-in support for dozens of wireless networking cards. You can check if your card has a FreeBSD driver[3]. If it does, it should "just work". A list of supported Atheros devices and known limitations can be found on the FreeBSD wiki[4].

PC-BSD® will automatically detect available wireless networks for supported wireless devices. You can verify that your device is supported by clicking the Hardware-Kompatibilität icon within the installer. If it an external wireless device, insert it before running the Hardware Compatibility utility. If your device is not detected, the Wireless Testing page has some information about drivers which have not been ported yet. It also contains instructions for converting a Microsoft driver to a FreeBSD kernel module, though results will vary by driver. Known missing wireless drivers are typically for the Broadcom and newer Realtek series of cards.

Einige zum Beispiel in günstigen Laptops verbaute Broadcom-Geräte sind stark fehlerbehaftet und können im DMA-Modus einen Systemstillstand verursachen. Sollte Ihr Gerät einfrieren, stellen Sie im BIOS in den PIO-Modus. Alternativ können Sie auch die Zeile'hw.bwn.usedma=0 in die Datei /boot/loader.conf einfügen und probieren, ob es nach einem Neustart funktioniert.

Hardwarekompatibilität überprüfen

If you wish to check your hardware before installing PC-BSD®, a good place to start is the FreeBSD 9.2 Hardware Notes[5]. Another good resource is to start the installer and click the Hardware-Kompatibilität icon.

While most hardware "just works" with PC-BSD®, it is possible that you will run across a piece of hardware that does not. It should be remembered that PC-BSD® is really FreeBSD, meaning that any hardware that works on FreeBSD will work on PC-BSD®. If you are experiencing problems with a device, start with a web search for the term "FreeBSD" plus the type and model of the hardware. This will let you know if there is a known issue with the device. If there are many search results, concentrate on the most recent ones as often hardware that used to be problematic has since been fixed or the missing driver will be available in an upcoming release of FreeBSD. If you experience problems with a device that should work but does not or you can not find any existing problem reports for your hardware, you can help improve hardware support for all PC-BSD® users by reporting the problem so that it can be addressed by the developers.
