           [*]   Hangul KSC5601 Symbol 16x16 font (NEW)

3. kernel build and installation

    Read /usr/src/linux/README and other kernel-related documents.

        $ make dep; make clean; make bzImage
        $ ...

    Install kernel using tools like lilo or loadlin. (include string
    "vga=ask" as a kernel command line option to specify graphics mode 
    at boot time)

        ex) /etc/lilo.cfg
        ...
        image=/boot/vmlinuz-2.2.2
                label=linux-2.2.2
                root=/dev/hda1
                read-only
    ->          vga=ask

        ex) loadlin
        C:\> loadlin.exe vmlinuz-2.2.2 root=/dev/hda1 vga=ask

4. reboot

    Use a value like 301(640x480), 303(800x600), 305(1024x768) or so
    to specify graphics mode for frame buffer console. (see 
    /usr/src/linux/Documentation/fb/vesafb.txt for detail video modes)

    * For booting directly with "vga=mode-number" you have to transform
    the numbers to decimal. (in "vesfb.txt")

5. check

    If you see the following messsages at boot, it works correctly.

        $ dmesg | more
        Linux version 2.2.2 (root@localhost) (gcc version 2.7.2.3) #6 Mon Mar 1 04:37:34 KST 1999
        Detected 233225883 Hz processor.
        Console: colour dummy device 80x25
    ->  Console: Hangul input on console is supported.
    ->  Console: Hangul output on fbcon is supported.
    ->  Console: default charset is KSC5601(ÇѱÛ).
        Calibrating delay loop... 465.31 BogoMIPS
        ...

6. etc

    To Toggle input language between hangul and english, press 
    'han/eng' key or <shift>+<space>.

    To use 3-beol hangul keyboard, use string "hangul=keyboard:3" 
    as a kernel command line option.

    Vesafb requires VESA BIOS Extensions v2.0. If your video card doesn't
    support VESA v2.0(ex. only VESA v1.2), try booting using "loadlin" 
    after loading VGA BIOS Extension utility like "UNIVBE" in DOS.

    To set terminal charset to KSC5601, do the following command.
            $ echo "\003[(C"
