So by following your advices I could get my function called. I had no
time to retrieve the current
sources patch from the development board, but basically I've pretty much
got same settings and
status as the legacy BIOS does.
Unfortunately, I still cannot get a VGA output. I start to get coherent
graphic output as soon Linux
loads the driver, but not before that.
Would you guys have a few additional pointers I could check?
