I have an old ASUS KFN32-D SLI/SAS dual socket-F motherboard that loves to randomly drop certain hardware on reboot. I upgraded the server about a year ago to have Dual Quadcore procs @ 2.5GHz with 32GB ram running SBS 2011. I would really like to continue using the server if possible. The devices that drop are the onboard NIC (link lights stay on however), and and all PCI slot devices (excluding the video card). This really sucks since there is no onboard IPMI device for me to use when I am away (and it loves to do this when I am away). Windows simply does not see the devices (there are no errors in device manager). The only way to fix this is to reset the BIOS to system defaults, reboot, and then re-enable the RAID controller (otherwise it will try to boot individual disks). Thinking maybe it was just a bad BIOS chip, I replaced it but that didn't help and I have re-flashed the BIOS many times. This only seems to happen to Server 2008, vista, and 7 on this board (I used to use this as my workstation). Odly enough it never happens with XP pro (x86 and x64) so I am not sure if it is a driver issue.
The motherboard does have a SMBus connector (6 pins: FAN_PWM, I2C_CLCK#, N/C, GND, I2C_DATA#, +5VSB) and I was wondering if I can do anything with that (IPMI?).
Another option is finding out how to use the RS232 port for remote management and then attaching that to another server/computer in the rack.
If not, are there any inexpensive IPKVM modules that I can get that that are sub $200 USD?
If you know what might be causing the system to do this, please let me know.
