Hi,
has anyone LinuxBIOS running on an Acer TravelMate 660 laptop? Or can tell me if it will work? I'm a LinuxBIOS newbie, but I hope the following information can help.

BIOS: Phoenix VGA-BIOS: Montara-GM 2965 (displayed in the info section of Phoenix BIOS, I don't know if this is important)
The display has a special resoltion of 1400x1050 and there is a known problem of the BIOS to not support this resolution. So I have to use the i915resolution tool on linux to be able to use this resolution.
Can LinuxBIOS initialize the VGA controller? Or can the original VGA BIOS be used in any way for that? I have seen something mentioned in other artices.
On the Acer site there is also a flash tool available. But only for windows. (WinPhlash). Maybe this can help if the LinuxBIOS flash tool doesn't work. http://support.acer-euro.com/drivers/notebook/tm_660.html
I understand why initialization of chipset, pci bus, etc is important. Otherwise the OS could not be started. But how important is the initialization of other peripherie like modems, USB controller, VGA, etc.? Isn't this done by the OS driver anyway after LinuxBIOS has started the kernel?

LinuxBIOS on laptops is a mess that we're only beginning to jump into. Laptops have an embedded controller, sometimes referred to as an EC, that can control everything from power to LCD control, etc, etc. The docs on these are usually covered by an NDA, with one real exception: the part used by OLPC's XO. See also http://www.linuxbios.org/Laptop
As for the rest of your hardware, I think some work was being done on the i855, but I don't know what the outcome of it was. The i82801dbm should work, either through the regular or generic implementation. You haven't listed the Super IO, so I can't tell if that would work or not, but there's a list of supported hardware on the LinuxBIOS wiki. The rest of the hardware can be dealt with later, although in a perfect world it should Just Work.

Thanks for the info.

Sounds not ver optimistic for me.

Actually I don't know what this Super IO is and where I can get this information from. Is there a tool like lspci available, or do I need to open my laptop?

Yeah, it's not trivial, sorry. Currently the OLPC is the only known laptop supported by LinuxBIOS. We _do_ intend to support laptops, but it's hard.

lm-sensors may or may not detect it. But the safest bet is looking at the hardware, of course (i.e., opening the laptop, which probably voids the warranty). But there's no need to do that anyway, see above. We don't support laptops at the moment, unfortunately.
