DOS 6.22 thumbdrive boot disk

Dell E1705

Specs: XP

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 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.

I'm a bit confused as to what you're trying to do here.
Are you saying that in order to update the graphic card drivers you need to be running BIOS version A10 ? Very odd if that's the case, I've never known a Dell laptop require a BIOS update prior to a graphic card driver update.

If that is the case however then it should be a fairly simple process to boot from a floppy disk and get your BIOS updated. Your best bet would be to get a Windows 98 bootdisk from Then, from within Windows stick a new floppy disk into your drive and run the Windows 98 exe file that you downloaded. It should prompt you to format the disk if it isn't already and it will then proceed to make the disk bootable. Once this is done you will need to copy the BIOS image and image installer program onto the floppy.

Reboot the laptop and boot from the floppy (either by setting the floppy drive to be the first boot device in the BIOS, or by choosing the boot menu - this is usually done by pressing one of the "F" keys when the DELL logo appears just after you switch the laptop on. It should tell you on that same screen which "F" key you need to press in order to choose a boot device - I think it's usually F10 or F12).

Once it's finished booting from the floppy you should see a black "DOS" like screen. From here simply use the BIOS installer program that you copied onto the floppy. You should already have instructions on how to do this from Dell when you downloaded the new BIOS file.

I don't understand why you need a battery. As long as your laptop is mains powered the BIOS shouldn't have a problem updating.

Thanks for the response, however I'm gonna need a bit more of a walkthrough here.

First, I've been told that the reason you need a battery, is that if you're running only on AC power, if the power cuts out for whatever reason while in the middle of a BIOS update, it'll fry the CPU or something. I'm not particularly computer savvy so I'm gonna need a little more explanation on your instructions.

First. By floppy disk, do you literally mean floppy disk or can I do this on a USB? I've heard of floppy disk emulators for USBs do I need to use one of these? I'm quite confused about how this whole process works. Also I've been told I need to run the BIOS update through DOS because only DOS allows me to use the /forceit function. If this is not true then I'd be glad to do WIN98.

When I try and run the DOS boot exe. it says insert floppy disk. How do this? Can I do it on a USB thumbdrive?

Finally what does this mean?

"Once this is done you will need to copy the BIOS image and image installer program onto the floppy."

I downloaded a BIOS Update exe file from, but what is the image you're talking about? Is that the image and now I need to find an installer program, or is that the installer and now I need an image?

I'm probably making this a lot more confusing than it is, but I really have very little experience in this kind of stuff. I greatly appreciate your help.

You can make a virtual floppy and let the tool extract the image to a virtual file image.Take that and burn to cd.

Normally you can update though windows too.

Might be able to do online too.

Also there are command lines for windows server 2003 see hp site.

Also other tools.
