What are example security features are implemented in modern BIOS setups?
A BIOS can now detect when devices or memory have been changed/altered, or even if the case/chassis has been opened or removed.
You can also set a BIOS-level password, though it is rarely used in the business environment.

How do the BIOS clock and the Operating System clock interact, and how do they differ?
Upon boot-up, the BIOS clock provides a time to the Operating System, at which point they become independent of each other and can differ even if by only milliseconds.

Will the Operating System clock and the BIOS clock differ? If so, how can you re-synchronize them?
Yes, by the nature of the software they eventually drift. The command hwclock can be used to re-synchronize the system clock and the operating system clock.

Does the BIOS handle daylight savings time?
No, many server admins choose to use UTC for this reason.

Are SCSI devices detected by a standard x86 BIOS? Can you boot from a SCSI drive?
No, but you can detect SCSI if the SCSI host adapter has its own BIOS included. Higher end SCSI host adapters generally have this capability, while the lower end ones do not.
Even with a host adapter that includes its own BIOS, you will still need to boot from PATA or SATA drive to detect the SCSI drives.
