DC-390U2B/W SCSI Adapter
INTRODUCTION
The DC-390U2B/W is an Ultra2 SCSI (Small Computer System Interface) bus to PCI bus
host adapter, which complies to the PCI 2.1 specification with Plug-&-Play (PnP) readiness.
Installing this adapter in your PCI system allows connection of up to 15 SCSI devices.
Your DC-390U2B/W is a 16-bit, Low Voltage Differential (LVD) / Single Ended (SE)
SCSI solution for your computer. It can support both legacy Fast SCSI and Ultra SCSI
devices, as well as the newest LVD Ultra2 SCSI devices.
The DC-390U2B/W supports ASPI (Advanced SCSI Programming Interface) managers for
most of the operating systems available today to assure operation with popular third party
applications.
Device drivers are also supported for the major operating systems for compatibility with a
full range of SCSI peripherals including CD-ROMs, Photo CDs, tape backups, scanners,
removable media and SCSI hard drives.
