Fried my laptop from water spill. Sent in to Dell got motherboard and video card replaced. Both components need to be updated. Video card cannot be updated until I flash BIOS to A10 (currently at A08, dont know why theyre sending me old version). Cannot flash BIOS in a standard way because I have no battery and do not want to buy a new one. So I've been doing some research on how to flash BIOS without a battery. I downloaded the update for the BIOS and to bypass the error message telling me I need to have a battery in to do the update, I tried doing cmd prompt then accessing the update from the desktop and adding /forceit afterwards. Then found out this force maneuver will only work in DOS. So I'm trying to figure out how to boot DOS. I downloaded a dos boot disk file called DOS 6.22 from Bootdisk.com. When I try to run it in regular windows it says "insert floppy to write" then I press ok, then it gives me the error message "the current image format is not supported by the disk drive. So I placed it in a thumbdrive, and then tried to boot boot it from there, but it just said error and press any key to restart. So what are the steps I need to take to boot from this USB thumbdrive? Do I need to format this thing, or do something to the dos file I put into it? I'm running XP on a Dell Inspiron E1705. Any help you can give me on this would be great. The screen refresh rate is so slow because this video card is not updated that it's making my computer painful to use.
