It says when chipset is not supported, UDMA is set automatically to UDMA33. I'm using 80 pin cable. 100%. "atacontrol mode acd0 UDMA6" returns: "current mode = UDMA33" "atacontrol mode acd0 PIO4" - mouse becomes extremly jumpy and there is no significant performance gain. disabling 80pin cable check in loader.conf through "hw.ata.ata_dma_check_80pin="0" gives me UDMA66 after reboot. The question: how do I enable full speed of UDMA133? Is it possible at all? ----------- dalibor
