Hi,
I found what I was looking for though - it was in the sgabios design.txt file instead of the revision history:
So, if I read the above correctly, it was lilo that inspired the "feature". Anyway, something to keep in mind.
Oh. lilo. Interesting.
I didn't expect http://www.qemu-advent-calendar.org/#day-1 becomes a useful testcase some day ;)
BTW, lots of good info in the rest of design.txt.
Guess I should have a closer look at it.
thanks for the pointer, Gerd
