SMART is a system where you can poll the disk for status info like
temperature, number of corrected reads, self-test results, etc.  Bad
block remapping will get done by the drive whether you use SMART to
monitor it or not.

It's not really a BIOS thing.  It depends on the hard drives you have.
You can install the smartmontools port to monitor SMART data for both
SCSI and ATA disks.
