By default, the internal SCSI bus is configured to run in Ultra 160 SCSI mode
(providing a maximum band-width of 160 MB/s). The user may configure
the SCSI system using the SCSISelect utility, included in the system BIOS.
Refer to page 99 for details about the SCSISelect utility. This utility is also
described in more detail in the SCSI User's Guide.
The Adaptec AIC-7892 Ultra 160 SCSI PCI controller is BBS compliant, but
does not support Hot Swap.
