Dear Hetz,

During Stage 1, Fedora boots in text mode. Then, Fedora Core 2 switches to=
=20
graphical mode when reaching stage 2. In the case of Fedora, I agree that=20
this works for both "-pci" and "-pci -cirrusvga".

On the converse,  SuSE 9.0 and Mandrake 10 are supposed to install in=20
graphical mode from stage 1 (probably in framebuffer mode, although I did n=
ot=20
read the source code of the installers). And graphical mode does not work f=
or=20
"-pci -cirrusvga" mode.

Here are some screenshots:

1) Mandrake 10

qemu -cdrom Mandrakelinux10.0-CD1.i586.iso -boot d -m 128 -pci

2) SuSE 9.1

qemu -cdrom SuSE-9.1-iso.disk1 -boot d -m 128 -pci=20

It seems like Cirrus SVGA framebuffer mode is not detected well.

Kindest regards,
