Actually... the card works in the Canyonlands using the latest u-boot from ftp.denx.de (u-boot-nand.bin-2009.11.1), though interestingly enough, this u-boot fails to detect an XGI Z11 video card that I have, whichever slot I put it in. in fact, the kernel itself detects the card and times out trying to get a link. It works with whatever u-boot I used to have in there (and no longer do ... oops :-) Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
