If you run out of ports and have the need for more use optical drives only on the marvel ports but you may still have slower boots your best bet is to trim your system to stay within the native ports. I even go so far as to disable all harddrives and optical drives as boot devices from the boot menu in the UEFI bios except the one I want to boot to. There are two places that need changes made boot order and boot devices so address both area then save and exit. There is one other area that needs to be changed go into UEFI bios (Advanced Mode) to the Advanced tab scroll down to APM and open then scroll dwn to Power on by PCIe, enable it and save and exit. This should correct your troubles. GL
I can't get into bios whatsoever, Ive even left the system on for around 1hr (about 4 times) just too see, bnut no joy, nothing on screen, no boot beep, nothing..
Have cleared the cmos sevral timeas and shorted the battery too.
Id say its not this problem you are mentioning, I hate the marvel controller and at one stage had it disabled but its not the issue here unfortatly.
I 'breadboarded' (that what you kids call it today im told) the system, had nothing but the cpu in it and gone from there, everything powers up fine the MB not showing any errors, and it's only the standard board so no flashy error code displays, But it dosent do the double boot anymore, and it did that every boot, so that's prob a big hint rioght there.
I have taken the board back and will have to find a replacement as the wait time for ASUS is around 4-8 weeks, which kinda sucks....Edited by ade42 - 12/1/11 at 8:49pm
