Single-Chip UltraSCSI
SUPER P6DBS/P6SBS has an on-board SCSI controller which is 100% compat-
ible with all major operating and hardware platforms. PCI 2.1 and SCAM Level
1 compliance are assured. Two independent UltraSCSI channels provide a per
channel data transfer rate of 40 MB/s. Connectors include two 68-pin 16-bit Ultra
Wide SCSI connectors (JA1/JA2) and a 50-pin 8-bit Ultra SCSI connector (JA3).
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).

Super I/O
The disk drive adapter functions of Super I/O chip include a floppy disk drive
controller compatible with the industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock gen-
erator, drive interface control logic, and interrupt and DMA logic. The wide range
of functions integrated onto the Super I/O greatly reduces the number of compo-
nents required for interfacing with floppy disk drives. The Super I/O supports four
360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250
Kb/s, 500 Kb/s or 1 Mb/s.
The Super I/O provides two high speed serial communication ports (UARTs), one
of which supports serial Infrared communication. Each UART includes a 16-byte
send/receive FIFO, a programmable baud rate generator, complete modem con-
trol capability, and a processor interrupt system. Both UARTs provide legacy
speed with baud rate up to 115.2 Kbps and also advanced speed with baud rates
of 230 K, 460 K, or 921 Kbps, which support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP) and also Enhanced Parallel Port (EPP) and Extended Capa-
bilities Port (ECP). Also available, through the printer port interface pins, are:
Extension FDD Mode and Extension 2FDD Mode allowing one or two external
floppy disk drives to be connected.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through SMI or SCI function pin. It also has auto power management to
reduce power consumption.
The Super I/O complies with Microsoft PC97 Hardware Design Guide. IRQs,
DMAs, and I/O space resources are flexible to adjust to meet ISA PnP require-
ment. Moreover, it meets the specification of PC97's requirement in the power
management: ACPI and DPM (Device Power Management).
