creating bootable flashdrives as your article states

i am trying to create a bootable flashdrive to download certain firmware files that i need to make my son’s hp pavilion xp media center- opticle drive work again. i read the article here and the tool from hp does not come up in their search as named here, nor does it show in the flashdrive registry that i can find. i am trying to keep from buying the kid a new computer when this is the only problem with it…i cannot download the firmware because it says i need to either use the cd/dvd that of course doesnt work, so it suggests creating a bootable usb drive to install this firmware. i cant find the hp tool and need some help if you can. thanks, kb
