How? The BIOS is doing the reading from those disks if it doesn't understand 
how to use the redundancy there is a problem.

I would be surprised if a "firmware" RAID system (like say a Promise FT100TX2 
or FT2300) would be any slower than using those disks on a comparable but 
non-RAID controller.

Once the OS starts it is its responsibility to maintain the metadata but it 
should still be able to get a good speed. I would say the requirement to sync 
the metadata to disk will slow it down but a pure software RAID system should 
do the same or risk array corruption.
