Some note on how I installed stuff on the AOhilo 5/10/2001.

0. Detail instruction from the Installation.txt document in the rtlinux
   documentation. This file are just my notes on what I did.

   The AP PC are:
      600Mhz Intel Pentium III
      64 MB RAM
      Intel CA810E motherboard (integrated video, sound).
         video requires agpgart(i810) option enable. 4MB video using RAM.
      Intel PCI EtherExpress Pro100 82557 -> use eepro100 driver.

1. Install a standard redhat 6.2 distrubtion.
   Added packages for telnet, rlogin, dump, rdist.

2. Untar and use the 2.2.18 kernel (this version is required by rtlinux 3.0).

   get the kernel from www.kernel.org

   > cd /usr/src
   > rm linux
   > bunzip2 -c /home/denault/download/linux-2.2.18.tar.bz2 | tar xvf -
   > mv linux linux-2.2.18
   > ln -s linux-2.2.18 linux

   Make and install the 2.2.18 kernel.
     - for the video card:
        [*] Prompt for development and/or incomplete code/drivers
        Character devices:
        <*> /dev/agpgart (AGP Support) (EXPERIMENTAL) (NEW)
        [*]    Intel I810/I810 DC100/I810e support (NEW)

   Recompile kernel, modules & install

      make dep
      make clean
      make install
      make modules
      make modules_install

   Do all the orther stuff:
      setup xwindow (see x86_and_810_howto.txt for hits on makeing XF86Config).

2. I download the rtlinux version 3.0 from www.rtlinux.com.

   Downloaded  rtlinux-3.0.tar.gz from www.rtlinux.com
   Untar file into /usr/src

     % cd /usr/src
     % gunzip -c /home/denault/download/rtlinux-3.0.tar.gz | tar xvf -
   

3. follow the Instruction in the /usr/rtlinux-3.0/INSTALL file.
   (tony's quick guide):

    create all the correct links.

    # cd /usr/src
    # ln -s rtlinux-3.0 rtlinux
    # cd rtlinux
    # ln -sf /usr/src/linux ./linux

    Patch the kernel.

    # cd /usr/src/linux
    # patch -p1 < /usr/src/rtlinux/kernel_patch-2.2

    Recompile kernel.

    # make menuconfig

    # make dep; make clean;
    # make install
    # make modules; make modules_install

    # reboot

    Install RT Linux.

    # cd /usr/src/rtlinux
    # make menuconfig (no changes)

    # make
    # make devices
    # make install

   
    Configure

      - edit /etc/rc.d to install rtl modules at boot time.
