Dear Hetz,

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

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

Here are some screenshots:

1) Mandrake 10
qemu -cdrom Mandrakelinux10.0-CD1.i586.iso -boot d -m 128 -pci -cirrusvga

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

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

Kindest regards,
