    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?

    > Please send your .config file.


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

    Thanks Randy.

    You should do "make oldconfig" immediately after editing the .config
    file (AFAIK). Or the "make menuconfig" might run the oldconfig
    changes for you.

    Then I would just double-check the final .config file
    to make sure that it contains what you expect it to contain.

    Sorry, I was not clear. The procedure was actually I type "make
    ARCH=arm menuconfig" first, then I could not find the CONFIG_ISA,
    CONFIG_NET_SPI and CONFIG_CS89x0 on config screen, this is still
    puzzles me why could "make menuconfig" displays all possible
    configurations on 2.6.22? Could you please explain?

    Because I was not able to add CONFIG_ISA, CONFIG_NET_SPI and
    CONFIG_CS89x0 from "make menuconfig", I used vim to manually added
    those and then "make oldconfig".

    > Then I would just double-check the final .config file
    > to make sure that it contains what you expect it to contain.


    Yes, I did double-check with the .config file, all three are =y.

    Thanks Randy.

    Probably not.

    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.
