SUPER P6DGS/P6DGE/P6DGU/P6SGU Manual
1-18
The SUPER P6DGS/P6DGE/P6DGU/P6SGU accommodates ATX power sup-
plies. Although most power supplies generally meet the specifications required
by the CPU, some power supplies are inadequate.
It is highly recommended that you use a high quality power supply that
meets ATX power supply specification 2.01. Additionally, in areas where
noisy power transmission is present, you may choose to install a line filter
to separate noise from the computer. You can also install a power surge
protector to help avoid problems caused by power surges.
1-7 Super I/O
The disk drive adapter functions of Super I/O chip include a floppy disk
drive controller compatible with industry standard 82077/765, a data sepa-
rator, write pre-compensation circuit, decode logic, data rate selection, a
clock generator, drive interface control logic and interrupt and DMA logic.
The wide range of functions integrated into the Super I/O greatly reduces
the number of components 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, com-
plete modem control 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 pins. 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 meet ISA PnP requirements.
Moreover, it meets the specifications of PC97's power management require-
ments: ACPI and DPM (Device Power Management).
