Hp 8200 Firmware Problem


i just read somewhere, that i could update my hp 8200a cd-writer to either a sony CRX 140E or a HP 9300i by flashing a new firmware into the writer.

when i tried updating to the HP 9300i i was asked for any installation-cd i should have gotten with the writer and i don´t have it, never got it…
when i try to upgrade to the sony it tells me there wasn´t any sony in my system (i used the D140E10N.EXE-file, wich is supposed to work, eh?

does anybody know more?
…would be cool, having a faster writer free!
