    Hi,

            This was first posted on freebsd-question, but I could not find
    the solution yet.
            Maybe you could help me.

            I´ve installed FreeBSD 5.4 on a new machine with the following
    hardware:

            Asus P4P800 SE (BIOS v. 1008)
            2GB RAM ( 4x 512 DDR400 )
            2 HDD Samsung SP0802N (80GB 7200rpm ata-100) 80 pins cable.

            The HD were formated with newfs defaults, and the following
    results were the same using both as master (primary e secondary) or with a
    master / slave (same interface).

            With diskinfo both performance are the same, but with "dd", the
    second disc (the slave or the secondary master), is always worst as if it
    were working in DMA2.

            what should be the right results?

            Here are the results:

            DD: dd if=/dev/zero of=TEST count=1000 bs=64k

            master: 60 Mb/s
            slave: 16 Mb/s

            The results with diskinfo (almost the same):

    /dev/ad0
            512 # sectorsize
            80060424192 # mediasize in bytes (75G)
            156368016 # mediasize in sectors
            155127 # Cylinders according to firmware.
            16 # Heads according to firmware.
            63 # Sectors according to firmware.
