I visited Intel support, but I didn't find comments (notes) to my monitoring.
Although the my DP67GB motherboard work correctly, I don't hear BIOS (POST) beep. I don't hear anything, possible Beep doesn't sound in normal boot.
I updated latest BOIS version too. If I press F8 (Windows 7 system boot menu), I hear the beep of motherboard speaker.
Possible "NO BEEP" is good or I have to set something in BIOS? Do I have to hear BEEP (0,5 sec correct code) Code?
Intel DP67BG motherboard
CPU Intel Core i5-2400 3,10GHz LGA1155 6MB
VGA ATI HD5750 Asus Formula 1G GDDR5 PCI-E Dual DVI-I / HDMI
HDD SATA Hitachi 500GB 7200RPM
During a Normal Boot , with no problems I don't think you will get a beep . Not all mother boards Beep at Boot.
