Bus Mastering
Fast, Wide, Ultra and Ultra-Wide SCSI Controllers for the PCI
Bus
 The
DC-390 is a SCSI (Small Computer System Interface)
bus to PCI bus host adapter, which complies to the PCI 2.1 specification
with Plug-&-Play (PnP) readiness. The maximum SCSI devices
supported are: DC-390/U (7) and DC-390F
(15). By using the Disconnect / Reconnect technique,
performance degradation during multitasking operations is prevented.
Other enhanced SCSI-2 features such as scatter-gather and command-tag
queuing are supported.
 The
DC-390 Series controllers support ASPI (Advanced SCSI Programming
Interface) managers for the following operating systems to assure
operation with popular third party applications such as:
- MS-DOS
- Windows
3.x/95
- OS/2
2.0/WARP
- NetWare
3.x/4.x
The on-board
menu-driven setup and jumperless design of the DC-390 Series
allow you to configure the host adapter, SCSI devices, and BIOS-related
parameters without opening your computer. The DC-390 Series also
provides a utility program that supports low-level formatting.
And with the help of the DC-390's installation software, the
drivers are easily installed and automatically update the CONFIG.SYS
and AUTOEXEC.BAT files.
The fully
intelligent solution provided by the DC-390 PCI to SCSI Host
Kit is ideal for multitasking environments such as OS/2, NetWare,
Unix, and Windows NT, as well as next generation operating systems
such as Microsoft Windows 95.
