Hello, Is there an option to set a specific transfer mode for an ata device, namely BIOSPIO for acd0 (acd0 on ata1-master)? The system waits a bit during boot and emits a message: -- ata1-master: FAILURE - SETFEATURES SET TRANSFER MODE timed out ata1-master: FAILURE - SETFEATURES SET TRANSFER MODE timed out -- and then -- acd0: DVDR <HL-DF-ST DVD-RW GWA-4080N/0C09> at ata1-master BIOSPIO -- I assume that the ata device driver tries to set a higher transfer mode for the DVD drive, fails, and then assigns the BIOSPIO transfer mode. I want to let the system not to try different transfer modes, but assign a specific one. The usual hint -- hw.ata.ata_dma="0" -- did not work The system is: FreeBSD 5.4-RELEASE #2: on HP nx9105, a laptop. Regards, Lyubich, M.
