DMA on Friday night server

I think I have DMA working on the Friday night server.

    hdparm -Tt /dev/hdb

    /dev/hdb:
     Timing cached reads: 348 MB in 2.00 seconds = 173.68 MB/sec
     Timing buffered disk reads: 64 MB in 3.09 seconds = 20.72 MB/sec
    [root@testb ~]# hdparm -v /dev/hdb

    /dev/hdb:
     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 = 65535/16/63, sectors = 81964302336, start = 0
    [root@testb ~]#

"hdb" is where all the data is.
