Actually it doesn't matter whether the BIOS supports it or not. Linux
does not use the BIOS. It only matters whether you disk controller
hardware can manage the feat.

No, this is not so. What matters is that your fastest device always be
the master. The slave device cannot run any faster than the master. The
master is not limited.

In fact (E)IDE can never access two devices at once. If software wants to
access two (e)IDE devices on the same channel, the OS must switch between
using each drive one at a time.
