yaboot: text mode or graphics mode?

[sumedh tirodkar]

Does anyone knw what happens when we boot into yaboot,whether we are
in text mode or graphics mode? If text mode then wat is the address of
the screen? I need it to print some debug info..bt i either dnt seem
to get the buffer address correct or i m not in text mode as yaboot
has already switched to some other mode...

Regards,
Sumedh

mode). Now i wish to switch back to text mode. how do i do this?

Unfortunately unless you are running some kind of yaboot-accessible or
firmware-accessible x86 BIOS emulation, this isn't possible.
