bus speed errato?
Se dispongo di mobo e hdd che supportano ata133 perché visualizzo questo
messaggio?
kernel: ide: Assuming 33MHz system bus speed for PIO modes; override
with idebus=xx
Ho provato da root:
hdparm -X69 -udma6 -d1 /dev/hda
ed ottengo:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
setting xfermode to 69 (UltraDMA mode5)
using_dma = 0 (off)
/dev/hda:
Mentre:
hdparm -i /dev/hda

Come mai? Come posso rimediare e impoostare il bus a 100?
Thx in advance
