It does not matter - and I did not mention that with one word - what SONY says but what those settings in fact do with the acpi of your laptop. Of course does the switched bit for unlocking the BIOS nothing to your ACPI.

You did overlook that hot switching on Vista does not work with "VGA Switching"="static" No way for hot switching from stamina into speed-mode (on Vista) with that BIOS-setting. > > >> However, in theory, this should not affect the switch. > > > > Where did you pickup that 'theory'?

Every second BIOS contains errors in the DSDT. What do you try to say with 'every second BIOS'? That is statistical speak. Not very helpfull while speaking about clearly defined issues. > So I just assume that everything works as it should, and if it does > not - try to fix it ;) Ah, OK. Then, to fix it, simply switch "VGA Switching"="auto" and boot your Linux with acpi_osi="!Windows 2006" because not _that_ is the 'hack' (like you wrote) but the switched BIOS is the real hack. After you switched it back to auto, everything will work again like it should. 'static' is only for debug purposes and, ok, maybe you don't want to use Vista, than its good. But please, feel free to switch it how you feel today ;-) You paid for that Hardware and you should be able to switch on any available setting. Locking BIOSes and Patents on crippling OSes like this one: United States Patent: 7536726 (No, not from Sony, from Microsoft but Sony wil certainly be one of its first appliers ;-) ) > > > Please write here if you have a better settings-combination as the > > default (not speaking about VT-settings) > > I'm not looking for "better" settings, but "VGA Switching", > "Intel VT" related stuff and ability to change hdd controller mode is > very helpfull. For what? To make Hot-Switching on Vista get stuck (SCNR!) But OK, you are right, BIOS should be open, at least for computer nerds (what it in fact is after unlocking) ;-) Regards, Raphael _______________________________________________ Mailing list: https://launchpad.net/~sony-vaio-z-series Post to : sony-vaio-z-series@lists.launchpad.net Unsubscribe : https://launchpad.net/~sony-vaio-z-series More help : https://help.launchpad.net/ListHelp
