Bios for Quad Core or Intel 2 Quad series still available?

We'd need to know what system model you have to point you toward the BIOS file.

thank's I allready have the A22 version installed on my 755 but will this version work with the Quad Core Q 9650?

Sorry, It's an Optiplex 755 Mini Tower with 305 Watt PSU.

The Bios is always there.  HOWEVER there are 22 versions and you cant jump from A00 to A22 in 1 leap or bound like superman.   DOS or XP is the recommended install medium.  64 bit versions of windows 8 or 10 ARE NOT recommended,  will crash and brick the machine.
