* 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 Iomega as a Jaz Jet PCI adapter.
|
||
|
|
* 3. This board has been sold by SIIG as the i540 SpeedMaster.
|
||
|
|
* 4. This board has been sold by SIIG as the i542 SpeedMaster.
|
||
|
|
* 5. This board has been sold by SIIG as the Fast SCSI Pro PCI.
