OK here I have a G5 PowerMac7,3 5.1.8f7 BootROM.

boot enet:,\yaboot

/chosen/bootpath = /ht at 0,f20000000/pci at 6/ethernet at f:10.13.0.16,\yaboot


It tries open

/ht at 0,f2000000/pci at 6/ethernet at f:, filename=yaboot.conf

Which works as expected.

Using \boot\yaboot also grabs yaboot.conf from \yaboot.conf not \boot
\yaboot.conf.

So it looks as if indeed net booting from non \ paths on pmac is broken.
The actual parsing code is based fairly comprehensively on 1275, but we
are After parse_device_path getting file=\0.  

It looks as if Przemek's analysis is correct, we are not handling this
properly.  Mac OF doesn't propagate the bootp arg to /chosen/bootpath I
need to see what pSeries does.
