3. How to load redboot & linux image & ramdisk to IXDP425

3.1 load redboot.bin
    - Use Flash Programmer
    - Choose device: Intel E28F128J3A
    - Put the chip in the burner and activate
    - Load file redboot.bin
    - Enable "Byte swap" via button
    - Start program

3.2 load zImage & rramdisk 
    - Connect EEPRO100 ethernet PCI to your PC
    - Connect IXDP425 to your PC via 1:1 mapping RS232 cable (Not Null Modem Cable)
    - On your PC run minicom and choose 115200,8N1,NoFlow
    - Power On IXDP425
