S1200KPR BIOS Recovery

[BScha9]

S1200KPR, E3-1225v2, 520SSD, 4G ECC Certified DIMMS. (One of 18 identical systems)

System will not boot after BIOS reflashed with custom settings. The flashed BIOS may have introduced a problem and in order to recover the system was unplugged, BIOS the Recovery jumper was removed, powered up for a few minutes, powered down, and jumper restored. But the system does not display any BIOS info and does not boot.

Curiously, with the jumper removed, power on results in a fan twitch every 2-3 seconds for 2 minutes, after which time the fan runs up to full speed and stays there with a triple beep alert. But no display.

The manual (http://download.intel.com/support/motherboards/server/s1200bt/sb/480922_g39481_002_s1200kp_productguide_r1_1.pdf http://download.intel.com/support/motherboards/server/s1200bt/sb/480922_g39481_002_s1200kp_productguide_r1_1.pdf) is not clear regarding what >should< happen when the recovery jumper is removed.

Any advise about how or if this can be restored?

Is there a specific name for the bios file on the usb drive? I tried KP0023.bio with results that the bios does not load and the behavior is unchanged. IOW, on power up w/out jumper, system still exhibits the fan twitch for 2-3 minutes then the triple beep (repeating every 5 secs) with fan on.

Any other suggestions to recover S1200KPR board?
