ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: chipset revision 16
VP_IDE: not 100% native mode: will probe irqs later
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx <- is my error?

i have a chip via82c686a (Epox 7-kxa)
at boot time is been detected via82c686a
proc says via82c586b
lspci -vvv no says
the udma capabilities is not work propetly i set manually with "hdparm -m 8 -W 1 -X udma5 /dev/hda"
whats happening here?
