A.4 | Power Configuration Settings |
| This section describes the features of your motherboard that deal with power and power |
| settings. |
| Slow Blinking LED for |
| When the CPU goes into a suspend state, the chassis power LED will start blinking to indicate |
| that the CPU is in the suspend mode. When the user presses any key, the CPU will |
| and the LED indicator will automatically stop blinking and remain on. |
| BIOS Support for USB Keyboard |
| If the USB keyboard is the only keyboard in the system, it will function like a normal keyboard |
| during system |
| Main Switch Override Mechanism |
| When an ATX power supply is used, the power button can function as a system suspend |
| button. When the user presses the power button, the system will enter a SoftOff state. The |
| monitor will be suspended and the hard drive will spin down. Pressing the power button |
| again to |
| power the system to keep the required circuitry "alive". In case the system malfunctions and |
| you want to turn off the power, just press and hold the power button for 4 seconds. The |
| power will turn off and no power will be provided to the motherboard. |
A.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 of 1 GHz |
| and faster. |
| The |
| power supplies generally meet the specifications required by the CPU, some are inadequate. |
| A |
| It is strongly recommended that you use a high quality power supply that meets ATX12V |
| standard power supply Specification 1.1 or above. It is also required that the 12V |
| connection (JPW2) be used for adequate power supply. 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. |
| The DLA Series does not have a function to determine |
| power supply will have the LED to show it is “OK” or “failed” by showing the color green or |
| amber for the respective status. When the power supply fails, it shows amber, when it is |
| functioning correctly it shows green. |
A.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 generator, 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 |
