.SH "DESCRIPTION"
.PP
Compute the best pio mode we can for a given device. Also honour
the timings for the driver when dealing with mixed devices. Some
of this is ugly but its all wrapped up here
.PP
The SI680 can also do VDMA - we need to start using that
.SH "FIXME"
.PP
we use the BIOS channel timings to avoid driving the task
files too fast at the disk. We need to compute the master/slave
drive PIO mode properly so that we can up the speed on a hotplug
system.
