DSDT & NVIDIA 9500 GT

[samersh94]

Hi all,

I have a XFX 9500 GT 1GB graphics card.

I've extracted the ROM from it using NVFLASH and I want to calculate the NVCAP from it. I've used "NVCAP MAKER" but I failed after adding the result in the DSDT.

Also I want to know how to calculate the buffer length in a DSDT Code, Should I count then add one then convert to hex?

[Cassio]

Add 0x before and , after each 2 digits, see example here http://Olarila.com/forum/viewtopic.php?f=19&t=609

Your method to calculate buffer size is correct (actually the "add one" part is only for strings), but you can just leave it blank and the compiler will count, see example in the link above.

Thanks for the quick reply but Is there a way to calculate the NVCAP from ROM directly?

[Cassio]

I have no idea. Isn't that what NVCAP Maker does?

It does but It's not working. So Should I use the NVEnabler's one ?

What about the non-string values, I mean how the buffer size is calculated?

You can try. There's some info about it in this topic

Just count, don't add one.

Again, you don't need to calculate, just leave it blank, the compiler will count.

I've made this code but it's not working at all, I don't know where the error comes from!

_ADR of PEGP is wrong, should be 0x00010000 according to your ioreg (pci-bridge@1).

You can remove this part

                                "",
                               Buffer ()

                               },

Also delete the size of Package inside _DSM.

Working perfectly

What about the "reg" entry should I fill it from IORegistry info or it is bumped automatically?

[Cassio]

Which "reg" entry?

Also what is the EDID? is it necessary?

[Cassio]

I don't think it's necessary.

About EDID you can read this (I think you don't need to inject it)
