PCI I/O Board Notes

This information applies to Sun Enterprise 6x00/5x00/4x00/3x00 server systems.
A.1

CD-ROM Drive Support

The Sun Enterprise PCI I/O board does not support audio volume control for the 4X
CD-ROM drives connected to the on-board SCSI interface.
A.2

UltraSCSI Bus Support

Currently only two Sun™ StorEdge™ (SPARCstorage™) configurations are capable
of supporting UltraSCSI transfers:
Two Sun StorEdge UniPacks (SPARCstorage™ Unipack)
One Sun StorEdge MultiPack 2 (SPARCstorage Multipack)
If your system does not have one of the above configurations, you must disable
UltraSCSI. You can disable UltraSCSI either for the entire system or for specific
controllers or individual drives.
A.2.1

Disabling UltraSCSI for the System

To disable UltraSCSI for the entire system, add this entry to the /etc/system file:
