D2500HN - Can't update BIOS

Hello

I have Intel Desktop Board D2500HN, witch BIOS "MUCDT10N.86A.0073.2012.1101.1638". But i cant update BIOS to newer versions from there:

Download BIOS Update [MUCDT10N.86A]

When i use "Express BIOS Update" from Windows, after reset updater program says is BIOS succesfully update. But after reboot i see old BIOS instead newly updated...

I create bootable DOS USB stick with iFlash BIOS Update, but after i start update computer restart witch no info on screen.

Any ideas to update BIOS to latest versions ?.

Thanks and regards.
