Fabrice!

it is almost unbelievable, how fast you are :-)

I tested two cases:

- booting Solaris 10

  It failed the last time without PCI support with this:

  http://tmp.janik.cz/QEMU/Solaris-10-x86-boot.png

  It still doesn't continue booting, but Boot path has been changed

  http://tmp.janik.cz/QEMU/Solaris-10-x86-boot-with-pci.png

  It is now /pci@0,0/pci-ide@3/ide@1/sd@0,0:a

  Solaris detection find both PCI Ethernet card and IDE. It is the same
  with Solaris 9.

- GRUB boot floppy with stage2.netboot
  (http://tmp.janik.cz/QEMU/floppy.img)

  In one project I'm working on, we use this image to boot the systems th=
at
  do not support PXE natively in BIOS. It is a simple GRUB floppy with
  stage2.netboot (supporting many types of network cards). The GRUB confi=
g
  file contains entries like:

  title xAPOSTclient
    dhcp
    root (nd)
    kernel (nd)/9.0/linux install=3Dnfs://10.7.7.104/install/9.0/CD1 auto=
yast=3Dnfs://10.7.7.104/install/9.0/xAPOSTclient.xml textmode=3D1
    initrd (nd)/9.0/initrd

  The card inside vmware is detected as

  http://tmp.janik.cz/QEMU/GRUB-vmware.png

  But in QEMU the detection seems to not work:

  http://tmp.janik.cz/QEMU/GRUB-qemu.png

  It detected RTL8139 (which is IMHO the default in GRUB when nothing
  detected properly).

Keep up the good work!
