Hi,
I just wanted to run QEMU CVS with EFI BIOS:
i386-softmmu/qemu -snapshot -L efi-bios -hda efi-bios/efi.disk
linux.img -net nic,model=i82551 -net user
i82551 is part of the E100 emulator (eepro100.c).
It does not work - no output on serial console nor VGA screen.
You tried ctrl-alt-2 to switch from vga to serial console? (Wild guess...)
Where did this bios come from?
...
Could you tell us more about what exactly you're trying to do?

Hi Rob,
thank you for your answer. I'm sorry that it took some time until I could
come back to this topic. Here is more information on what I was trying to do
(which still does not work).
I heared from Tristan's mail that EFI BIOS network functions only support
eepro100 hardware. Well, I wrote the eepro100 emulation for QEMU, so
I wanted to see this working.
So, I compiled i386-softmmu/qemu from QEMU svn trunk, got
http://fabrice.bellard.free.fr/qemu/linux-0.2.img.bz2 and
http://fabrice.bellard.free.fr/qemu/efi-bios.tar.bz2, unpacked both
files, and finally had this directory:
$ ls -l efi-bios/
insgesamt 24712

-rw-r--r-- 1 stefan stefan 35328 26. Apr 13:18 vgabios-cirrus.bin
vgabios-cirrus.bin is a copy from qemu/trunk/pc-bios.
Now, I started this command:
i386-softmmu/qemu -snapshot -hda efi-bios/efi.disk -hdb
efi-bios/linux-0.2.img -L efi-bios
Result: no output in VGA console, no output (beside serial0 console) in
serial console.
Of course I did not try ctrl-alt-2 to switch to the serial console (this
selects the monitor
console), but ctrl-alt-3.
Obviously, some earlier CVS revisions had worked. So I started with QEMU
CVS of
2007-03, and it worked! Up to now, I could narrow the change from
working to no
longer working to the time interval from 2007-10-07 to 2007-10-13.
