The BIOS does not provide drivers, it provides access. As I understand
it, if there is support in the BIOS, then an OS does not need to provide
it's own means of access - no driver needed.

I have not made an exhaustive review of systems and devices. So far one
KB, a trackball, and an IDE HDD in a USB case work on some machines.
What I have made the most use of is the USB HDD on my laptop while
booted from the DFSEE CD. If I select the USB support option on the
DFSEE CD access to the HDD FAILS.

My newest MB is probably two years old. I'll see if I can determine
something definitive. Note: if the BIOS is going to provide access to a
device then the device must exist when the the BIOS is looking for
devices, which is during boot. You don't plug it in later like you
might with an OS that has - and needs - it's own driver.
