I have a MB from an HP XW9400 Workstation, and I need to find out some of the pinouts, which I cannot locate in any HP docs, including the 216 page HP XW9400 Service and Workstation User Guide (or whatever it is called). The MB is a modified (for HP) TYAN S2915 board, and has some proprietary connectors on it - in particular, the Front Panel Header (2x10 pins) and the CPU Fan headers, which are 5 pin (not 3 or 4 pin as for standard MB CPU Fans. TYAN won't help me on this; I have sokent to them as well...
Do any of you have this information? The board is unuseable for me at present because of these header pinout problems.
Thanks in advance!
