[ixp1200] Question on setup ENP2505, urgent!

[feng]

Hello,
I got a ENP2505 board from my supervisor. He joined the intel IXA 
university program.
But when I tried to setup this board according to the IXA Education 
Workstation Setup Guide, I always failed in Section 7. After I finished 
install software for ENP2505 and tried to boot the board using " 
./bootixp " boot script, the board always entered a Cygmon environment 
and also I can not see the message "Finished ENP-2505 driver install" as 
mentioned in this guide. Then I tried to ping the board in another 
terminal window, it failed. I thought it's true. Because actually the 
Linux system do unknow the board currently.
So, is there anybody know which options I should choose before I boot 
the enp2505 board. VxWorks, System Monitor or Cygnmon mode in this step?
Do u know what's the problem?
best,
feng
