thats not 100% accurate. I had the 3650 gddr3 and had a start up issue. It was like the card needed to heat up for a short time then after powering off and on again it would start

[shark300]

I found error string (ERROR: MXM Structure not found or invalid. Reflash MXM ROM or add MXM Structure and associated callbacks to SBIOS! POST will be halted for 30 seconds and performance will be limited to balanced performance mode until this is resolved...) in vBIOS dump. I will disassembl this code, and the counter decrement to 1. or 0.

Wow awesome job!

You should post a tutorial to get this thing works for every 9600m user.

[shark300]

Maybe.

@shark300 you are on the right track i think, the phoenix bios is problematic as it seems to be uneditable with any Bios editor out yet
if you just kill the timeloop out of the aw and fsc bios that would be neat! otherwise we have to wait for an new bios editor to leak out.

PM me and i provide you with the bios or whatever help i can give out.
You already unpacked it? WinImage? it's not that hard to get hands on it but editing won't be easy. Finally one who knows disassemble bios code

@Meins321:
I made a little modded vBIOS. I flashed a new bios on my videocard yesterday, but the notebook didn't boots. I reflashed it with original vBIOS, and notebook is working, but this has startup delay.
I'm working on the problem.

MOD:
New idea, new version of vBIOS, but my pendrive is broken. I'll flash tomorrow (today )

Yeah, we can easily find the error string in the disassembled bios, event with the Hex view of Nibitor, the trick then is to find where the countdown loop is located to modify it, which I couldn't figure out due to my lack of knowledge in assembly language. Still, this is a partial fix just to trick the countdown, it wouldn't fix the card being used in PCI-x x1 instead of x16 (I guess), and the full support of the card by the bios.

This card can use PCI-e x16, but can't use PowerMizer 2, 3 level. I hope, this problem is resolved in future.

i thought that the error comes from the Laptop bios? not from vbios in mxm, as the mxm table is stored in the vbios but the error code from halted boot comes from the laptop Bios because it can't access the mxm table wich is now different from that old gpu vbios?

If youre right then this is just the wrong forum and maybe someone can help us elsewhere.

Maybe it helps but i don't know for sure:
I've downloaded IDA Pro Free
open ida.cfg file in the IDA Pro installation folder with text editor , then delete the default processor for *.rom file.
then open vbios -> chose processor: metapc -> "NO" only 16 bit disassemble -> here you go should be asm code next to an hex editor

btw, what did you use as thermal interface material? any good heatpads around? or copper and as5

[EDIT] ok deleting the text isn't that hard as you can do it with any HEX editor but then the crc check fails and you have to force the flashing, i will look into that too but i think it's hard to accomplish for me as i can read any asm

[EDIT2]@shark300 does that mean you only have 30s countdown? no beep beep and so on? as i find only the beep annoying and i would wait for a good GPU 30 Sec ,-P

Maybe it helps but i don't know for sure:

I use IDA, too. I can disable to write error code, but I have delay yet.

[shark300]

No beep, just waiting.
I didn't delete error text, I disabled.

This card can use PCI-e x16, but can't use PowerMizer 2, 3 level. I hope, this problem is resolved in future.

When looking into GPU-Z, the software says I'm in PCI-X x1, and I've seen the same for other people. Can you check with yours? Or maybe GPU-Z is wrong...?

About the beep, I just have to plug headphones in the line out to shut them down.

Everest, GPU-Z say for me, I use my card in PCI-e x1 mode, but 3DMark, and RivaTuner say x16...

[TehSuigi]

I think we can safely say that GPU-Z is misreading the card when it's not on a 4 Series chipset (Centrino 2) - NightWalker's Asus C90S showed the 9600M GT he upgraded to running at 1x without any negative impact on benchmarks, and ditto for justinwalker's upgraded Acer Aspire 6920G over on NotebookReview.

[Meins321]

that means apart from 30sec wait with an error text displaying were done?
and i think that GPU-Z is misleading because when the x1900m came to light as an upgrade, i thought that it was crippled because of GPU-Z
and mailed some details to wizzard on techpowerup.com; with the next update it showed the correct values, apart from that i was next to the benches on notebookcheck.net

@shark300, thank you for that does that mean that you can disable the error entry point but not the 30sec countdown in vbios? that's nice!
