1-5 Power Supply

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.

The H8QM3-2/H8QMi-2 accommodates 12V ATX power supplies. Although most power supplies generally meet the speciﬁcations required by the CPU, some are inadequate. A 2 amp current supply on a 5V Standby rail is strongly recom- mended.

It is strongly recommended that you use a high quality power supply that meets 12V ATX power supply Speciﬁcation 1.1 or above. Additionally, in areas where noisy power transmission is present, you may choose to install a line ﬁlter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges.

Warning: To prevent the possibility of explosion, do not use the wrong type of onboard CMOS battery or install it upside down.

1-6 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 genera- tor, 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 components required for interfacing with ﬂoppy disk drives. The Super I/O supports two 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.

It also provides two high-speed, 16550 compatible serial communication ports (UARTs), one of which supports serial infrared communication. Each UART in- cludes 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 of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems. 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 a SMI or SCI function pin. It also features auto power management to reduce power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be ﬂexibly adjusted to meet ISA PnP requirements, which support ACPI and APM (Advanced Power Management).
