I have a HP DVD Writer 640c which is now ES04. It used to be fine. Now with a new version of windows 7 it is now coming up as a plain old cdrom drive. I have the bios I want to flash it to. A BenQ 1625. I need Windwflash.rar to do that I am sure. I cant seem to find that file anywhere. All the links are over 5 years old and do not work anymore. Any help on this matter would be greatly appreciated.

Since you are trying to get information on a BenQ crossflash, I’ve moved your thread into that subforum. Welcome to the forums, and hopefully, one of the members informed on this subject will help.

Thanks fixed it using MCSE.
