Still having problems...  still looking for help...

I exchanged the 256 MB dimm for the same kind from PNY.

I have exactly the same problem.  The old 128 MB works,
the 256 MB dimm works neither alone nor in combination
with the 128 MB dimm.

The failure is always the same.  POST succeeds; w2k blue-screens
immediately after the screen switches from character-cell to
graphics mode.

A little more information:

The machine has a creative nvidia geforce 2 video card.
Why does it always fail right when the video card goes to
graphics mode?  I'm pretty sure I tried disabling video
bios shadowing.  Maybe the video card causes a voltage
dip when it kicks in.

Also, the new 256 MB dimm worked in another machine.
I believe (not certain) that the second machine was set for
pc133 memory.   I don't know what the motherboard was.

Some people say that the motherboard just might not like
that brand of memory.  Would anybody have suggestions
for a brand of memory that the abit-ka7 might like better?

Thanks.
