1-8 AIC-7896 MultiChannel
TM
Single-Chip
UltraSCSI Controller
The Super I/O controller provides support for one PC-compatible
printer port (SPP), Bidirectional Printer Port (BPP), Enhanced Paral-
lel Port (EPP) or Extended Capabilities Port (ECP). Also available,
through the printer port interface pins, are Extension FDD and Ex-
tension 2FDD Modes, allowing one or two external floppy disk drives
to be connected.
The SUPER P6DGH has an onboard Adaptec SCSI controller, which
is 100% compatible with all major operating and hardware plat-
forms. PCI 2.1 and SCAM Level 1 compliance are assured.
Two independent Ultra II LVD SCSI channels provide a per channel
data transfer rate of 80 MB/s. Connectors include two 68-pin 16-bit
Ultra Wide SCSI connectors (JA1 and JA2) and one 50-pin 8-bit
Ultra SCSI connector (JA3). The AIC-7896 Ultra II SCSI chip con-
nects to a 32-bit PCI bus. You can connect up to 15 devices (seven
8-bit internal and eight 16-bit internal or external SCSI devices, or
15 Wide internal and external SCSI devices).
The Super I/O provides functions that comply with ACPI (Advanced
Configuration and Power Interface), which includes support for
legacy and ACPI power management through an SMI or SCI func-
tion pin. It also features auto power management to reduce power
consumption.
The Super I/O complies with the Microsoft PC97 Hardware Design
Guide. IRQs, DMAs and I/O space resources can flexibly adjust to
meet ISA PnP requirements. Moreover, it meets the specifications
of PC97's requirement regarding power management: ACPI and
DPM (Device Power Management).
