Hello,
I have motherboard Intel DG33BU with E8400 @ 3GHz, 1 GB Kingston DDR2 2.2V
I tried to update BIOS, but it is not happening. Only two ways work half way. From CD and from windows, but all end in same way: when from i boot from CD, first i see CD boot screen, i need to press enter, then i need to press enter to start flashing, after i pres enter, i see iflash2 version info and after ~10seconds it seems that computer turns off, but the light that indicates that PC is on is still lit. I turn off PC completely and turn it on and everything work, but BIOS is not upgraded (obviously) . From updating from windows after pc reboot it just turns off the same way just doesn't show any update screen.
I need do upgrade BIOS because when i put 4x1GB ram my vista x64 runs very slow.

We have two identical PCs with identical mother board, the other PC updated its BIOS without any problem.

Any suggestions?

Check the bios settings on both boards and using the working one, set the other one completely identical (apart from the serial number ofcourse). Use this bios for the update:

I know it's an ancient thread, but I have the exact problem.
Did you ever find a solution?

I think somewhere in the bios you need to enable flashing in the security settings, did you visit the Intel support pages for your board to check the documentation?
