I recently stepped into a problem with my HTPC wich reduces to the above mentioned configuration: the HDD is pefectly recognized by the BIOS SATA driver ver 1.10.05 of the latest BIOS (NBG4310H.86A.0107.EB.EXE) when warm-booting, but is not -at least not completely- detected when cold booting. If I stop the Bios with 'Pause' for a second early enough (before device detection: the SATA driver displaying dots ...) the drive is also recognized.
I checked and changed the power supply line, I tried all the HDD PreDelays (which seemed to have no influence at all - no IDE devices?), I switched all meaningful alternatives (esp. hiding/displaying extension board text) in the BIOS, and googled, all to no avail.
There is just one detail: the SATA driver always displays "06 Ports, 01 Devices" and either the HDD-code or "No device", the BIOS on the contrary shows either also the HDD code or -thats the hint for an existing and only partially recognized drive- a <totally blank entry> where the HDD code usually is, whereas for all other ports "No device " is shown.
Usually the HTPC is just suspended but in the rare case of deep trouble it has to be powered off (no reset button) and so the problem came up. Are there any suggestions, please?
Thank you in advance!
