FreeBSD will take advantage of Physical Address Extensions (PAE)support on CPUs that support this feature. A kernel with thePAE feature enabled will detect memory above 4gigabytes and allow it to be used by the system. This featureplaces constraints on the device drivers and other features ofFreeBSD which may be used; consult the pae(4) manual page for more details.

Most modern laptops (as well as many desktops) use the AdvancedConfiguration and Power Management (ACPI) standard. FreeBSDsupports ACPI via the ACPI Component Architecture referenceimplementation from Intel, as described in the acpi(4) manual page. The use of ACPI causes instabilities onsome machines and it may be necessary to disable the ACPI driver,which is normally loaded via a kernel module. This may beaccomplished by adding the following line to/boot/device.hints:
The following systems are partially supported by FreeBSD. Inparticular the fiber channel controllers in SBus-based systems arenot supported. However, it is possible to use these with a SCSIcontroller supported by the esp(4) driver (Sun ESP SCSI, Sun FAS Fast-SCSI and Sun FAS366Fast-Wide SCSI controllers).
Where possible, the drivers applicable to each device or classof devices is listed. If the driver in question has a manual pagein the FreeBSD base distribution (most should), it is referencedhere. Information on specific models of supported devices,controllers, etc. can be found in the manual pages.
Note:The device lists in this document are being generated automaticallyfrom FreeBSD manual pages. This means that some devices, which aresupported by multiple drivers, may appear multiple times.
This driver also supports target mode for Fibre Channel cards.This support may be enabled by setting the desired role of the corevia the LSI Logic firmware utility that establishes what roles thecard can take on - no separate compilation is required.
With all supported SCSI controllers, full support is providedfor SCSI-I, SCSI-II, and SCSI-III peripherals, including harddisks, optical disks, tape drives (including DAT, 8mm Exabyte,Mammoth, and DLT), medium changers, processor target devices andCD-ROM drives. WORM devices that support CD-ROM commands aresupported for read-only access by the CD-ROM drivers (such ascd(4) ). WORM/CD-R/CD-RW writing support is provided bycdrecord(1) , which is a part of the sysutils/cdrtools port inthe Ports Collection.
The em(4) driver supports Gigabit Ethernet adapters based on theIntel 82540, 82541ER, 82541PI, 82542, 82543, 82544, 82545, 82546,82546EB, 82546GB, 82547, 82571, 82572, 82573, 82574, 82575, 82576,and 82580 controller chips:
Most adapters in the Intel Ethernet 700 Series withSFP+/SFP28/QSFP+ cages have firmware that requires that Intelqualified modules are used; these qualified modules are listedbelow. This qualification check cannot be disabled by thedriver.
The mlx5en(4) driver supports 100Gb, 50Gb, 40Gb, 25Gb and 10GbEthernet adapters. ConnectX-5 supports:10/20/25/40/50/56/100Gb/sspeeds. ConnectX-4 supports:10/20/25/40/50/56/100Gb/s speeds.ConnectX-4 LX supports:10/25/40/50Gb/s speeds (and reduced powerconsumption) :
The sis(4) driver supports Silicon Integrated Systems SiS 900 andSiS 7016 based Fast Ethernet adapters and embedded controllers, aswell as Fast Ethernet adapters based on the National SemiconductorDP83815 (MacPhyter) and DP83816 chips. Supported adaptersinclude:
The Farallon EtherWave and EtherMac card came in two varieties.The ep(4) driver supports the 595 and 895 cards. These cards havethe blue arrow on the front along with a 3Com logo. The Farallon595a cards, which have a red arrow on the front, are also calledEtherWave and EtherMac. They are supported by the sn(4) driver.

The snd_hda(4) driver supports more than two hundred differentcontrollers and CODECs. There is no sense to list all of them here,as in most cases specific CODEC configuration and wiring are moreimportant then type of the CODEC itself. 2ff7e9595c
