Hello! I was wrong, found a new BIOS on http://www.asrock.com.tw/support/download/dl_k7vm2.htm#bios which I didn't see the first time. Now it works fine. So if one with a ASRock Mainboard an Promise Controller asks again, tell him/her to update to 1.90 Bios. Thanks for all the help and support messages I recieved, keep on doing such a good job! Greetings, Nico P.S.: Are you interested in debugging a ECS Mainboard with Transmeta Crueso on it? I own a ECS A530 notebook, which has ACPI, but does not - blank screen (x does, console not) - support ACPI sleep states (or at least panics after them) - ... If so, I would subscribe the acpi list and give you more details about it.
