.SH "DESCRIPTION"
.PP
Get the SCSI operational parameters from PDC.
Needed since HPUX never used BIOS or symbios card NVRAM.
Most ncr/sym cards won't have an entry and just use whatever
capabilities of the card are (eg Ultra, LVD). But there are
several cases where it's useful:
o set SCSI id for Multi-initiator clusters,
o cable too long (ie SE scsi 10Mhz won't support 6m length),
o bus width exported is less than what the interface chip supports.
