FreeBSD - Collecting hardware information

Finding hardware information in FreeBSD can be performed using dmesg, pciconf, usbdevs, atacontrol and dmidecode utilities.

I will start with finding information CPU on FreeBSD:
# grep -i cpu /var/run/dmesg.boot
CPU: Pentium III/Pentium III Xeon/Celeron (501.14-MHz 686-class CPU)
cpu0: <ACPI CPU> on acpi0

(don't expect some mainframe :D ). Above is a 500Mhz Pentium III

Determining hardware platform and processor architecture:
# uname -mp
i386 i386

Physical and available memory
# grep -i mem /var/run/dmesg.boot
real memory  = 268369920 (255 MB)
avail memory = 248635392 (237 MB)

Information on the PCI slots using pciconf
# man pciconf
PCICONF(8)              FreeBSD System Manager's Manual             PCICONF(8)

     pciconf -- diagnostic utility for the PCI bus

     pciconf -l [-cv]
     pciconf -a selector
     pciconf -r [-b | -h] selector addr[:addr2]
     pciconf -w [-b | -h] selector addr value

     The pciconf utility provides a command line interface to functionality
     provided by the pci(4) ioctl(2) interface.  As such, some of the func-
     tions are only available to users with write access to /dev/pci, normally
     only the super-user.
     With the -l option, it lists all devices found by the boot probe in the
     following format:

     foo0@pci0:4:0: class=0x010000 card=0x00000000 chip=0x000f1000 rev=0x01 hdr=0x00
     bar0@pci0:5:0: class=0x000100 card=0x00000000 chip=0x88c15333 rev=0x00 hdr=0x00
     none0@pci0:6:0: class=0x020000 card=0x00000000 chip=0x802910ec rev=0x00 hdr=0x00
     If the -v option is supplied, pciconf will attempt to load the ven-
     dor/device information database, and print vendor, device, class and sub-
     class identification strings for each device.
# pciconf -lv
