qemu uses "pci" as name for pci bridges in the firmware device path.
|
|
|
9ae3a8 |
seabios expects "pci-bridge". Result is that bootorder is broken for
|
|
|
9ae3a8 |
devices behind pci bridges.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Some googling suggests that "pci-bridge" is the correct one. At least
|
|
|
9ae3a8 |
PPC-based Apple machines are using this. See question "How do I boot
|
|
|
9ae3a8 |
from a device attached to a PCI card" here:

|
|
|

|
|
|

So lets change qemu to use "pci-bridge" too.
