Hi Mike,

I'm a newbie on the list, and I'm just wondering about support forums for OpenBIOS ... is there an IRC channel that one could get help implenting/installing? I have an old Dell d600 I got cheap at a garage sale, that doesn't recognise its hdd, cd drive, or usb for booting -- people have said that I must have a bad BIOS. Is this machine a good candidate for OpenBIOS?
Probably not. But you can check the list of motherboards supported by coreboot here: http://www.coreboot.org/Supported_Motherboards

Log: Macio: Fetch nvram offset from fw_cfg if available
We want the hypervisor to tell us where NVRAM lies so that we do not have to rely on hardcoded addresses for it.
Introduce a new fw_cfg interface that allows us to receive it at runtime.

Log: PPC: Add kernel header style typedefs
When compiling OpenBIOS on openSUSE 12.3 ppc64 I end up getting real host headers included that make use of the __uxx and __sxx types.
Define those too in our asm copy of the types.h file, as that one overrides the host's types.h that we would've used otherwise.
