Footnotes:
1. This board has been shipped by HP with the 4020i CD-R drive.
The board has no BIOS so it cannot control a boot device, but
it can control any secondary SCSI device.
2. This board has been sold by SIIG as the i540 SpeedMaster.
3. This board has been sold by SIIG as the i542 SpeedMaster.
