I was wondering if anybody knew what to do in a situation like this:

I have a 2 year old laptop that is pretty crappy, but it lives.

It's cd-rom, external powe4r port, and video port dont work, and the graphics are really red and it ruins gaming. and the wireless internet adapter just went out, so I want to reinstall it, I have a bootable version of the xp install disk on a usb but the bios is way out of date(no usb boot support) and it won't let me flash it on battery power and it doesn't have a floppy version(I have a external floppy drive). so I eather need a way to trick my computer into thinking it's running off of external power, make a flash bios floppy, or get a floppy that boots usb's. PLEASE HELP!,
