After you ran "make oldconfig" ? I don't know much about ARM configs. You should probably be asking about this on some linux-arm mailing list. However, I did make ARCH=arm s3c2410_defconfig and that particular board config enables ISA. Then if I enabled NET_PCI, I can also enable CS89x0. The default ARM config (if there is one) doesn't seem to enable ISA. --- ~Randy Phaedrus says that Quality is about caring.
