Question about finding the latest firmware

I have a Dell Inspiron 5160 with a CD-RW/DVD Drive model HLDS GCC-4243N, I am looking to download the latest firmware and I went to the Dell support site and found v.A103 released 6-6-2005, however when I did a search in Google I came across a higher firmware version on the HP site v.1.08 released 6-6-2005, my question is does each manufacture customize these firmwares to work only on their systems or can I install the HP firmware v.1.08 to work on my Dell?

The [B]Dell OEM[/B] firmware is the correct obe for your drive!
