Dell m4400 Blue Screen

I recently purchased a Dell Precision m4400 notebook. All was well for a few weeks until out of the “blue” it started blue screening on boot. Safe mode reported some VMM start-up problem, which didn’t really mean much to me (I assumed it was Virtual Memory Manager).

So I did’t what all good developers do, cracked the s#!$% and formatted it. All was well for another few days. Then it started again – this time I was completely sure I hadn’t changed something.

This time, rather than jumping in and reformatting, I decided to try “investigation”.

Long story short, it was an option in the BIOS, on the Virtualistaion tab, “Enable Direct I/O” or something similar. I disabled this and no more bluey 🙂
