VGA Problem about 440bx chipset

[Gerald Chiu]

Hello,Adam,
I have problem on booting win2000,but the ADLO status said win2k is fully 
supported.

The information displayed on screen is below:

===============
Please select the operating system to start:
Microsoft Windows 2000 Professional
Microsoft Windows 98

Use your arrow keys to move the highlight to your choice.
Please touch Enter to choose.
Seconds until highlighted choice will be started automatically: 0
For troubleshooting and advanced startup options for Windows 2000, press 
F8.
================

When I choose win2k and touch Enter,it halts, the screen even not change to 
show progress bar!
When I choose win98 ,after showed the welcome logo,it halts with the cursor 
flashing on the left_upper corner of screen.

I want to boot win2k, then could you give me some idea on debugging?
