Hi everyone. I've had a thread going here on the lists about DMA
problems in 133 mode. In a nutshell, some drives give DMA_WRITE and
DMA_READ errors when in 133 mode with certain configurations, however
don't have any problems in 100 or 66 mode. After looking in to many
solutions I think I'm just going to run it at 100, since from my
research the benefit isn't that noticeable.
I know about atacontrol to set it manually, but I'd like to set UDMA100
mode automatically on boot since I have 5 hard drives. I also know the
sysctl hw.ata.ata_dma, but that doesn't say anything about using 100 vs 133.
Thanks in advance.
-Mark
