Looks like the same chipset as my laptop. In order to get DMA working I had to set CONFIG_IDE=n and enable SCSI cdrom support and CONFIG_SCSI_ATA_PIIX. Your cdrom device will become /dev/sr0 and you shouldn't have any issues with DMA. > > > Istvan > > > > -- > > gentoo-user@gentoo.org mailing list > > -- > > "Dan ketika Guru Isa mendengar derap sepatu datang > ke pintu kamar mereka, dia merasa damai dengan rasa > takutnya yang timbul.
