Hello,

Can someone explain to me the following log messages from the kernel:

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH2: IDE controller on PCI bus 00 dev f9
ICH2: chipset revision 2
ICH2: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xff00-0xff07, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xff08-0xff0f, BIOS settings: hdc:DMA, hdd:DMA
hda: 39102336 sectors (20020 MB) w/512KiB Cache, CHS=2434/255/63, UDMA(100)

Using `hdparm -t /dev/hda5` I get ~27MB/s.
Does it mean that my bus holds back my HD.
Shouldn't I get 100MB/s?
Can I do something to improve performance.

Thanks,
Yuval Scharf
