Hello,
I have dh67bl configured so it turns on after AC power supply is lost and renewed again. It works, but very strangely. After the AC supply is renewed, bios freezes on the first intel logo screen, without any text displayed. It stays like this for ~80s, and then it continues with boot sequence normally. Also when this happens, bios seems to ignore all settings regarding the boot sequence speedup (do not turn on graphics, USB and boot just from HDD).
I observed this behavior only after AC power is lost, when I just restart the system or turn it off and on again without AC disconnected, it boots at normal speed. Also it does not matter if I have any peripheries connected (USB, ETH) and boot order settings does not influence it neither (I have enabled only boot from HDD as #1 option).
Some details about my board
model: dh67bl
version: aag10189-213
bios version: blh6710h.86a.0160 (newest available)
I would be grateful for any tips what might be causing the problem. Also turning on any debug messages during boot sequence would definitely help - but I have not found any switch enabling this.
thank you
Entik
