Scsi/Pci Lan Combo Board Features - HP X Class 500/550MHz Reference Manual

Ultra Wide (16-bit) SCSI Controller
The Ultra wide 16-bit SCSI controller can support up to 15 devices (internal and external).
HP V Personal Workstations are supplied with a 16-bit wide external connector
ISUALIZE
and an 8-bit narrow internal cable (which can support up to two devices). Data is
transferred at 40 MB per second on a 16-bit wide, single-ended bus.
By default, the internal SCSI bus is configured to run in Ultra-SCSI mode (providing a
maximum band-width of 40 MB/s). The user may configure the SCSI system using the
SCSI Configuration Utility, included in the system BIOS. This utility is described in more
detail in the section "Symbios Logic SCSI Configuration Utility" in the chapter "HP BIOS."
SCSI-configured-automatically (SCAM) support is provided at level 2, for Plug and Play.
However, hot swap is not supported. The controller is BIOS Boot Specification (BBS)
compliant.
