@valuxin hey, if you are still here and could help.. i got Dell m6600 (A18 bios) with W6170M from HP (109-C600A1-01_02) and the only vbios working with this is FirePro_M6100_VER015.035.000.003.045435-Dell. Some of other (from HP or MM) doesn't show picture (black screen) and i need to reflash vbios back via remote desktop.. MM vbios shows the picture but vga doesnt work, i can not setup drivers.. Original from Dell ver 15.040.... doesn't work, from HP doesn't work..
any advise? i think all should work if I could mod only Device ID by myself.. from 0x6646 to 0x6640
