The SCSI BIOS can be accessed at boot time with some special key sequences (Ctrl+A for most Adaptec host bus adapters, Ctrl+G, Ctrl+M, or other keys for other vendors) and allow you to set up some parameters. Bootable SCSI and more.

In order to get SCSI information, use scsi_info or hdparm.

Examples: 

scsi_info /dev/sda
hdparm -grv /dev/sda

obs: Tested with hdparm v6.1 (debian sarge kernel 2.6.8-3 arch 386)
