The most impressive thing about this board is its widest range of
BIOS settings. In all other respects, this is usual but pretty fast solution.
The layout is not very handy, but the PCB is too small. The IDE ports are behind the PCI ones, but their sideways mounting musn't create any problems. The FDD connector is on the board's left edge, and its cable may worsen free air circulation and be an obstacle when handling connectors on the PCB. The audio connectors are in front of the PCI slots, and the power supply connector is tucked right in the center. It's not easy to reach some jumpers when the board is already installed. Their functions are indicated on the PCB. The 3-phase switching voltage regulator incorporates 4 capacitors of 3300 uF and 3 of 1200 uF. There are also voltage regulators of the AGP bus (2 x 1000 uF) and of the memory (1x1000 uF and several less capcious ones). The board measures 305x190 mm ("narrow ATX", 6 fastening screws, the front edge may hang loose without additional fastening).
System monitoring is supported by Winbond W83697HF chip. It controls:
No wasted space for components that didn't get included in the final design. Well, this is a more advanced version among two based on the same PCB: the other - KD7A - is based on KT400A+VT8235 and has limited functionality (Serial ATA and one of the USB 2.0 ports are not soldered on).
