    I don't have my embedded system here, I'll try when I get there. But,
    let me clarify it, did you mean to type "make defconfig" on linux
    (kernel) directory, and enable ISA, NET_PCI and CS89x0 from the
    prompt?

    My procedure was to edit .config to enable ISA, NET_PCI and CS89x0
    from vim, then type "make menuconfig" and "make oldconfig" (The same
    procedure I did in 2.6.11 which works fine). Does that make things
    differently?

    I'll, but I don't have the system right now.

    Thanks Randy.
