The only options I have through sysctl are hw.atamodes, and hw.ata.ata_dma both of which only allow turning DMA on and off. I would like to leave it on, but force the controller to use UDMA4 (ata66) instead of UDMA5 (ata100) Is there a method for this, or is it an on/off proposition? -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
