FWIW, I get the sae MSI message on my Dell Opti 755's, but other than one maybe 2 minute delay on 1 of 8 machines, they all have worked flawlessly. I think the difference is I'm booting from CD and those with problems have been PXE booting. It could well be a BIOS/Firmware problem with the 755's PXE stack that we're seeing and no amount of tweaking is going to solve it. It might be worth testing other bootable linux stacks which use dhcp to get an address and see if those have the same issues.
