SCSI Bus

The embedded SCSI controller on the motherboard:
•
Supports up to seven drives.
•
Provides 8-bit fast narrow SCSI support for up to three 5.25-inch internal, half-height
removable-media devices.
•
Provides 16-bit ultra SCSI support for up to four 3.5-inch, internal hard disk drives.
NOTE: Two half-height removable-media devices can be substituted for one
For Windows NT, adding or removing drives may require rebooting the
operating system. Certain RAID controllers may permit hotswapping of
drives without de-allocating drives and rebooting the operating system.
