Something very strange happens to me: I connect 1 SATA harddrive to my Asus K8V SE De luxe on the primary VIA sata port. I disable the onboard Promise controller as I do not need it.
I power up the pc and the harddisk is not found, I recheck all connections and everything is OK. I restart again but no harddisk. Then I reboot using
alt-ctrl-del and hey presto....harddisk!
It works all the time: "cold" start from switched off is NO harddisk and reboot with alt-ctrl-del is YES harddisk.
Temperature is not an issue because this works on a cold computer as well.
