I've built 2 images: one on SP2/FP2007 and the other on
SP2/FP2007/UpdateRollup1. First runs on a AMD MB, second on an Intel.

Now: my application writes a few files to a USB flash drive. On the first
image when the flash LED stops blinking I can remove it, plug it into a PC
and my files are there. On the second, after the initial flashing stops if
I pull it out - no files. If I leave it in, 20-30 seconds later there's
more LED activity, then if I pull it my files are there.

So: was write caching turned on in UR1, or is this a function of my
hardware? Are there registry entries that control this?

If someone has any insight I'd be grateful.

Thanks,
Dean
