A kernel with the PAE feature enabled will detect memory above 4 gigabytes and allow it to be used by the system. This feature places constraints on the device drivers and other features of FreeBSD which may be used; consult the pae 4 manpage for more details.
FreeBSD will generally run on ibased laptops, albeit with varying levels of support for certain hardware features such as sound, graphics, power management, and PCCARD expansion slots. These features tend to vary in idiosyncratic ways between machines, and frequently require special-case support in FreeBSD to work around hardware bugs or other oddities.
When in doubt, a search of the archives of the FreeBSD laptop computer mailing list may be useful. The use of ACPI causes instabilities on some machines and it may be necessary to disable the ACPI driver, which is normally loaded via a kernel module. The acpi 4 manual page has more information on how to do this via loader tunables. Most devices that can be found in or are compatible with ia64 machines are fully supported.
The notable exception is the VGA console. As such syscons 4 can not be enabled and the use of a serial console is required. High-resolution mode is not supported.
For background information on the various hardware designs see the Sun System Handbook. If you have a system that is not listed here, it may not have been tested with FreeBSD 8. The following systems are partially supported by FreeBSD. In particular the fibre channel controllers in SBus-based systems are not supported. Starting with 7. This section describes the devices currently known to be supported by FreeBSD. Other configurations may also work, but simply have not been tested yet.
Feedback, updates, and corrections to this list are encouraged. Where possible, the drivers applicable to each device or class of devices is listed. If the driver in question has a manual page in the FreeBSD base distribution most should , it is referenced here. Information on specific models of supported devices, controllers, etc.
This means that some devices, which are supported by multiple drivers, may appear multiple times. Controllers supported by the amr 4 driver include:. Note: [amd64, i] Booting from these controllers is supported. EISA adapters are not supported. Then conclude by installing the mps driver and telling the bootloader on the hard drive to load it. Just in case anyone else runs into this. These instructions work great with FreeBSD 8.
However, there was one more thing I had to do to get the installer to see the hard disk after loading the mps. Hit Q to exit Options. You must be logged in to post a comment. Figure 1: Select 'Fixit' instead of an installation method. Figure 3: The 'Fixit' Prompt. September 27, at pm. The use of ACPI causes instabilities on some machines and it may be necessary to disable the ACPI driver, which is normally loaded via a kernel module.

In particular the fibre channel controllers in SBus-based systems are not supported. Starting with 7. Sun Fire V support first appeared in 7. Sun Fire V and centerplanes only, for which support first appeared in 7. This section describes the devices currently known to be supported by FreeBSD.

Controllers supported by the amr 4 driver include:. Note: [amd64, i] Booting from these controllers is supported. EISA adapters are not supported. Cards supported by the isp 4 driver include:. All major firmware revisions 2. The following controllers are supported by the mpt 4 driver:. This is to avoid issues with potential memory fragmentation during later system up time, which may result in failure of allocating the contiguous memory required for the contigmem kernel module.
There are two ways to enable sending and receiving of jumbo frames via testpmd. One method involves using the mtu command, which changes the mtu of an individual port without having to stop the selected port. Another method involves stopping all the ports first and then running max-pkt-len command to configure the mtu of all the ports with a single command. To configure all the ports at once, stop all the ports first and run the max-pkt-len command as follows:. Overview of Networking Drivers 2.
