I'm building a disk imaging station and assembled a system around a PEAK 650 Socket 370 SBC board. The board does have a few tiny passives knocked off from rough handling (looks like a screwdriver was used to pry off the tabbed CMOS battery instead of snipping it off) but it still POSTS fine, to a degree. BTW this is the PhoenixBIOS D686 BIOS.
Like any other system with a reset CMOS or a flat battery it will give you the CMOS CHECKSUM ERROR - DEFAULTS LOADED message after the memory count and drive detection and then you can press F1 or DEL to carry on and it will, but at any point after that if you reset the machine it will give you the one long beep POST error and a POST display card gives you C1 so its hanging up really early in POST. You have to pull the battery or otherwise remove power to the CMOS to clear it and POST successfully again.
Curiously if I immediately jump into the setup and select LOAD FAIL-SAFE DEFAULTS the problem goes away and I can reset the machine all day long without it failing so right now I'm having to set something in the SETUP and reboot to see if I can find what setting between the fail-safe and the Optimal/default valees is making it trip up but I'm curious what it might be. I have tried to set the machine up in the basic configuration right now with everything extra pulled but it's still running with 256mb of PC100 and a 1ghz Tualatin and can't really tell if perhaps it's running into a speed/timing issue. Does kind of issue sound familiar to anyone?
