Power Supply Requirements

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates of 300 MHz and above.

The SUPER 370SBA/370SBM/370SLA/370SLM accommodates ATX power sup-

plies, and the 370SBM and 370SLM accommodates the new SFX 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 which 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 the

computer from noise. It is recommended that you also install a power surge

protector to help avoid problems caused by power surges.

Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk drive

controller that is compatible with 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 (16550

UARTs), one of which supports serial infrared communication. Each UART

includes a 16-byte send/receive FIFO, a programmable baud rate generator,

complete modem control capability, and a processor interrupt system. Both

UARTs provide legacy speed with baud rate up to 115.2 Kbps as well as an

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), Enhanced Parallel Port (EPP) or Extended Capabilities Port

(ECP). Extension FDD and Extension 2FDD Modes are also available through

the printer port interface pins to allow one or two external floppy disk drives to

be connected.
