How to create a DOS bootable USB pendrive?

Healer
I want to create a bootable USB stick with DOS so that I can update the BIOS of one of my computers. I search around I can only find those using Linux and I can't run DOS program after boot-up from Linux. I don't have a DOS system running but an XP and Windows 7. So I don't have access to a DOS system to run "format d: /s" command and so on.

I have tried to use diskpart list disk but it doesn't recognize USB pendrive.

Is there something downloadable from the Internet so that I can create one? Thanks!

might give FreeDOS a try, it's one that has a modicum of recent development.

I beleive I have done it before. I just formatted the pendrive like a floppy disk and ran the sys command and created a config.sys file and a autoexec.bat file. Now I don't have a DOS environment to do it.

I would need to install the FreeDOS before it can be useful, wouldn't I? I have found the web site http://www.z80.eu/freedoscd.html talking about changing the live CD to cover SATA drive. However it looks somwhat tedious to me. I am trying to avoid it at this stage.

hp.com has 2 programs that create a bootable usb. if i recall, they format the usb in such a way that allows a boot sector to be created on it. afterwards you can then install an operating system on it as well, like windows.

I have downloaded and installed the HP Drive Key Boot Utility. By default it creates a Linux disk. The contents are as follows. It does make provision for adding a floppy image as a boot option but I can't find it anywhere. I have tried bootdisk.com. For some reasons, they are all executable files, not image files. I don't have floppy disk to be created as a boot floppy. I am just trying to create a bootable pendrive using a bootable floppy image unless there are other alternatives. I remember I saw it there before.
