Hi. The problem isn't in OBP setting, but in the fb's setting in linux.

mode "1152x900"
    geometry 1152 900 1152 900 32
    timings 0 0 0 0 0 0 0
    accel true
    rgba 8/0,8/8,8/16,0/0
endmode

This is the actual setting and evidently isn't correct. I read the man of
frame buffer, but i've not understood the sintassi to change fb modes. When
i was using an intel processor & lilo, I used "VGA=ask", but I don't know
if I may use the same solution to find the right resolution with a blade,
silo and elite card.
This is a piece of my silo.conf:

##
read-only
timeout=10

image=1/vmlinuz.new
        label=Linux.new
        initrd=/boot/initrd.img.new
        root=/dev/sdb5

Is it possible to insert VGA=ask to check possibilities to change
resolution? Where it's necessary to put "VGA=ask" to obtain what I'm
finding?

TIA
Antonio
