Assuming you’ve gotten your MSI Wind, the first thing that you’re going to want to do is to upgrade the firmware. My MSI Wind came with version 1.06 of the firmware, which is a bit older than the current. The current firmware is 1.10 (or 1.0B) and can be found here.

I did things a bit backwards, and just dove in on installing OSX. When I decided that I should upgrade the firmware, I had a bit of a problem. The firmware upgrade procedure involves running a DOS utility that will re-flash the firmware, and in installing OSX on my Wind, I had erased the only real DOS machine I had available. Eventually, I was able to burn a bootable DOS image onto a 128Mb USB thumbdrive that I had around, put the firmware on there, boot off it, and install the firmware. I’m not a windows user at all, but I suspect that there is a way that you can boot into a basic windows command line interface, and do the upgrade from there. I leave it to the reader to figure out the best method for them, but I am now very happy to have a bootable USB drive already setup for the next time I have to do this.

At the time I did my install, I went from firmware 1.06 to 1.09, since that was the most recent at the time.. Some of the changes in the firmware have been noted to give the MSI Wind a ~30% speed boost. Another notable change is that you gain the ability to overclock the Wind anywhere from 8% to 24%, simply by pressing Function + F10.
“Simply” is slightly misleading here. You do have to do a little setup in the BIOS, and pre-determine how fast you want to overclock. You have the option of 8%, 15%, or 24%.
Once you select it in the BIOS, you boot into your OS, and then when you press Function + F10, you get overclocked to the rate you’ve set in the BIOS. This is handy for seeing if your machine can handle the overclock. If it can’t, you can back out of it very easily.

I’m not running my Wind overclocked. I couldn’t tell any notable difference for my computer, and generally I want more memory instead of more CPU. Other people seem happy with the ability though.
