>Description:
ata(4) says :
To see the devices' current access modes, use the command line:
sysctl hw.atamodes
which results in the modes of the devices being displayed as a string
like this:
hw.atamodes: dma,pio,---,pio,dma,---,dma,---, (--- = no device)
This means that ata0-master is in DMA mode, ata0-slave is in PIO mode,
and so forth. You can set the mode with sysctl and a string like the
above, for example:
sysctl hw.atamodes=pio,pio,---,dma,pio,---,dma,---,
The new modes are set as soon as the sysctl command returns.
while it should refer to atacontrol(8) to change ata modes
since the sysctl hw.atamodes doesn't exists anymore.
>How-To-Repeat:
man 4 ata
