[Qemu-ppc] qemu-system-ppc and PXE boot

[Rafał]

Hello,
 
A want to run PowerPC using PXE boot. I typed simple:

qemu-system-ppc -boot n

The result is: "No valid boot device for G3 Beige machine", and ppc machine 
doesn't start.
Trying on i386 platform and... everything OK: qemu-system-i386 -boot n starting 
with no problem, and machine try boot from network.

Quick check of what google knows about "No valid boot device for G3 Beige 
machine:

ppc.oldworld.c

 #if 0
287                 if (boot_device[i] >= 'a' && boot_device[i] <= 'f') {
288                     ppc_boot_device = boot_device[i];
289                     break;
290                 }
291     #else
292                 if (boot_device[i] >= 'c' && boot_device[i] <= 'd') {
293                     ppc_boot_device = boot_device[i];
294                     break;
295                 }
296     #endif
297             }
298             if (ppc_boot_device == '\0') {
299                 fprintf(stderr, "No valid boot device for G3 Beige 
machine\n");
300                 exit(1);
301             }
 
No n switch expected.
 
 Does that mean that the network(PXE) boot for PowerPC is not implemented?
My Qemu version is 1.5.3 running on x86 Gentoo. On windows qemu (version 
2.5.50) i get the same: PowerPC machine not starting, i386 starting.
