1. To create a bootable USB memory stick, download the files attached to this article (hpusbfw.zip and dos.zip).
2. Unzip these files and remember where each is located. Connect the USB Flash Drive to be used and execute HPUSBFW.EXE.
3. Click on Create a DOS startup disk, then choose using DOS system files.
4. Browse to where the DOS boot up files were unzipped and press OK.
5. To begin creating the DOS bootable USB flash drive, press Start.
6. When prompted to confirm that all items on the USB drive will be deleted, press OK.
7. When this process completes, the USB drive will be able to boot the machine into a DOS environment. This becomes a useful tool for running diagnostic software (Seatools, memtest, etc) or for flashing the latest BIOS. Depending on the model, the setting in the BIOS to choose in order to boot from a USB key is USB-ZIP or the manufacturer of the USB drive itself.
