Bootable USB-Stick BIOS Update

bootbios.zip Ultimate BIOS-Boot-Edition (all-in-one: CD, Floppy, USB-Stick) 5.6MB
The Ultimate BIOS-Boot-Edition contains the following files for creating a bootable USB-Stick:
usbdos.zip (the archive contains the 3 MS-DOS system files command.com, io.sys and msdos.sys, which must be decompressed with a packer program like Winzip or Winrar)
HP_USB_Boot_Utility.exe (the setup program contains Hewlett-Packard's Format-Utility for USB-Sticks under Windows)
The DOS system files are normally unvisible, because their file attribute is set to hidden. If you would like to show these hidden files, you have to enable the option: "Windows-Explorer / Tools / Folder options / View / Show hidden files and folders" and to disable the option "Hide protected operating system files".
