hi!
i've been trying around for quite some time now trying to start qemu without 
the graphic screen... can someone tell me exactly what I'm supposed to do??

i want to redirect the output of my i386 debian linux to my host-console (also 
a i386 debian) to fully see the output of a kernel panic (see previous 
messages i have posted).

i'm starting qemu:

qemu -hda myimage -boot c -kernel-kqemu -kernel mykernel -initrd 
myinitrd -append "root=/dev/hda1 console=/dev/ttyS0" -nographic

after tons of trial-and-error i finally got my system to boot, however, the 
login-screen is not displayed (i see all output of the starting system up 
until the ">>login:"). how do i connect to the serial line now to get to the 
login??

i have tried minicom, however that seems to just hang :-(

should i use (tell qemu to use) a different "virtual" serial console?? how to 
i start minicom correctly?? could you give me the parameter set you guys are 
using for
1.) qemu
2.) connector (minicom???)
3.) what i have to enable inside my guest-system (i have checked 
that /etc/securetty include ttyS0 already)

any help will - as always - be greatly appreciated!!
thanks :-)
