I've gotten a few hints from another person who has a 'slightly' = different eval board, there have been several 'points' which were not = clear, and for which I hardwired some hacks to overcome. As it is, I don't see many people using the ppc other than Apple = variants, G4/G3, etc. I've gotten the kernel up, mounted a NFS root system, etc. but at the = last point I left things, I was looking at the code that assigns the = interrupt line from the Atheros PCI-Express card to however that is = handled 'logically' to 'real' in the kernel. One of the hacks I made was getting the freeBSD kernel 'pci' code to go = beyond seen the processors 'pci' config registers, as there are 2 pcie = interfaces, and then 'seeing' the atheros cards. It appears that the atheros cards are 'INTA', but that doesn't tell me = what interrupt 'number' is the 'logical' numbering scheme, although I = can sort of determine which 'pic' interrupt is being used from the CPU = manual. If this sounds a bit foggy, I've not looked at this in a month as I've = been on vacation, and now have other 'priorities' to attend to. I would however like to get back to this port at some point. Thanks, John Clark. PS Adrian -- You have a wiki on a mips port to a TPline wr-1043 device=85 what would = be required for the tplink-wr842nd=85 tnx
