  Getting Information about the Hard drive and list all PCI devices.

               $ hdparm /dev/hda

                 /dev/hda:
                  multcount    = 16 (on)
                  IO_support   =  0 (default 16-bit)
                  unmaskirq    =  0 (off)
                  using_dma    =  1 (on)
                  keepsettings =  0 (off)
                  readonly     =  0 (off)
                  readahead    = 256 (on)
                  geometry     = 16383/255/63, sectors = 234375000, start = 0

           or for SCSI

               $ hdparm /dev/sda

           Try it with the -i option for information

               $ hdparm -i /dev/hda

               /dev/hda:

               Model=IC35L120AVV207-1, FwRev=V24OA66A, SerialNo=VNVD09G4CZ6E0T

           How fast is your drive?

               $ hdparm -tT /dev/hda

               /dev/hda:
               Timing buffer-cache reads:   128 MB in  0.41 seconds =315.32 MB/sec
               Timing buffered disk reads:  64 MB in  1.19 seconds = 53.65 MB/sec

           Need to find your device?

               $ mount
                  or
               $ cat /proc/partitions
                  or
               $ dmesg | egrep '^(s|h)d'

                  which for my system lists:

                     hda: IC35L120AVV207-1, ATA DISK drive
                     hdc: Lite-On LTN486S 48x Max, ATAPI CD/DVD-ROM drive
                     hda: max request size: 1024KiB
                     hda: 234375000 sectors (120000 MB) w/7965KiB Cache, CHS=16383/255/63, UDMA(100)

            By the way, if you want to turn on dma

                $ hdparm -d1 /dev/hda
                  setting using_dma to 1 (on)
                  using_dma    =  1 (on)

       
    List all PCI devices

               $ lspci -v
