Hi, everybody

I designed an arrandale mother board, and
have written an OS on vmware.

Now I want to write my own BIOS, but
it seems hard to get datasheets I need, eg programmer's guide.

So, I want to know. How does everybody here get those
datasheets you need in writing you own BIOS? Or does
coreboot support arrandale? So I may refer to it if I can
get the datasheets I need.

I also designed a Tunnel Creek mother board, so this
is another alternative of me.

If the motherboard you designed uses an Intel chipset, then it should be very easy to find the relevant datasheets for that chipset. Intel publishes all of them on their web site, where everyone is free to download them for whatever reason.

If you designed the chipset yourself, then you'd have to ask yourself for the datasheet.

Application developers develop applications. OS developers develop OSs. Firmware developers develop firmware.

Put simply, I doubt anyone here has bothered writing their own BIOS. We're OS developers, not firmware developers.

Thank you for your fast response.

The problem is that, I'm currently developing TI davinci system,
so I don't have the privilege to the Intel website in next 1 year
or longer. So I need another way.

I always want to develop a computer system that is totally designed
by me. For now I don't have the time to designed any IC. So I
only need to develop hardware, BIOS, OS.

I am now not in the X86 project anymore. I did
download some other datasheets, but that is not engough.

Maybe I should download them next time I am in the x86 project.

Intel publishes documents freely, you don't need an account.. what are you talking about?

I am afraid you are wrong :<
