Hiya Folks! Just to get this info into the archives since it's not in the manual for the motherboard. I recently bought an ASUS P2B-N motherboard to run 3.1 on and when it arrived I got a rude shock. The pinouts for the front panel connections weren't listed. The connector was noted, but that was it. I called ASUS and waited on hold for about 25 minutes and when I talked to the tech he was as amazed as I was at the lack of info and agreed to research it and send it to me. P2B-N riser card no pin 1 9 VOL_UP FP_RST 2 10 VOL_DN MSG_LED 3 11 MSG_LED IDELED1 4 12 IDELED2 LANLLED 5 13 LANLLED +5V 6 14 FP_SLEEP SOFT_ON 7 15 GND PWR_LED 8 16 PWR_LED The only thing I was concerned with was powering the box up, so after some further research on the motherboard spec I discovered that to power up the motherboard requires momentary contact between pins 7 and 15, and to put it in sleep mode again requires momentary contact between pins 7 and 15. The other nasty shock was that while the motherboard is advertised with two UltraDMA IDE connectors, one of them is a proprietary ASUS connector for their "slim" cd-rom drive, so you actually only have one available. Otherwise I am very pleased with the board. A custom case was built that is exactly 2U high and the risercard+processor+power supply fits heightwise with just a little to spare. It is possible to either jumper or change in the BIOS settings all the doodads (ie. sound, floppy, serial ports, mouse, ...). I turned off almost everything except for what's listed in the dmesg below. I booted the box off the 3.1 Release CD I ordered from cdrom.com and away I went.
