The distribution of the interrupt lines is described more fully in the section “PCI Interrupt
Request Lines” in the chapter “HP BIOS.”
Ultra-Wide (16-bit) Small Computer System Interface (SCSI)
Controller
The Adaptec AIC-7880 Ultra-wide SCSI PCI controller is integrated on the HP V
ISUALIZE
Personal Workstation system board. Data is transferred at 40 MB/s on 16-bit wide,
single-ended bus. The controller is fitted with a 16-bit SCSI flat cable with five connectors,
plus a SCSI termination device; so a maximum of five internal wide-SCSI hard drives are
supported.
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
SCSISelect utility, included in the system BIOS. This utility is described in more detail in
the SCSI User’s Guide.
