Don't you people ever need to apply BIOS updates?
My motherboard (Asus P5Q) allows me to place the BIOS update file onto a USB drive (or floppy, if you wish) and then you just enter the flash tool from the BIOS. No messing around with DOS. Most modern motherboards appear to have this functionality now.
...but it's a gigantic 1920x1200 mofo. I could always connect my old 1280x1024 also, but thus far I actually haven't needed to.
Same here, apart from the fact i've also attached my old 1280x1024. It's great to be able to have something displayed on the secondary screen while you're working on the primary one. Beats alt-tabbing by a mile!
If in any problem you find yourself doing an immense amount of work, the answer can be obtained by simple inspection.
