9300m GS on 5520g

[snejk]

Hello all,

my name is Tom and this is my first post here. Recently i bought Nvidia 9300m gs for my 5520g since the laptop had faulty 8600m GS and i got sick of repairs. I replaced them and it worked. On boot i had 30 sec delay because of invalid MXM structure but i fixed it with .Netrolller modded bios. Everything else works flawlessly. But now the problem is that my external DVI and s-video ports cant recognize anything. Even in NVIDIA Control panel it only shows internal display and VGA port. My VGA port works without problems. Can anyone tell me what to do?
Do i need to mod BIOS or VBIOS to get the dvi working?

Thanks in advance

i added bioses.rar and original acer bios 1.33 for 5520g in the attachments.
bioses.rar file contains my current 9300m GS vbios, old vbios from 8600m GS and current modded SBIOS.
