I would love a mod removing the whitelists and adding advanced menu to my bios too. Link here : https://drive.google.com/file/d/1cmm8M1313pjP9hkfm23EfXuEOHyxYHmW/view?usp=sharing . Thank you for your work!

Sad to hear that. You managed to pull the vbios of 8850m from the bios of samsung models? What modification did you perform on the vbios(i guess something about the 2gb vram part)? I was hoping you would go for the 6730m, but i guess its now up to me to do the honors . I should try it once i get my hot air station, since core swaps are somewhat expensive here in greece (about the cost of a new hd4650 ).

Have you tried the original 240m vbios? I could extract this 550m vbios from the asus n43sn bios: https://mega.co.nz/#!R9wiCACJ!SeeNvzcZLish0Y8nbfmAmz6ncb4PPgFJQG6sNQJ652c . I still dont think this will work because of the mxm parts missing but i would love to be proven wrong . Been searching for that 8850m vbios too, but the samsung models seem to be the only ones with ddr3 vram. And because of the way samsung supplies bios updates, have not been able to get a proper dump of the sBIOS to extract the vbios from. Hope you have more luck on that project.

Nice work slv7! I extracted the bios from 5537 as well but only found the gddr5 version of the vbios so(since they wont do for this mod) i didn't upload them. I cannot download the vbios files due to some forum issue, so did you manage to extract it from the samsung as well? It's probably the only one on the market right now with the ddr3 vbios.

It seems like i did a mistake identifying the bios and it is in reality the hd 6650m vbios with 2 gb ddr3 vram. So back to square one. I'm trying to extract it from the Asus A43SA bios but i am having no luck(does asus use any obfuscation techniques to hide the vbios?) ,as i can not seem to find the bios of the only other laptop that contains the 6730m, the Nexoc E643. If anyone has the bios file(or could dump it) for this laptop, i'd appreciate a link. Edit: I got it. I extracted it from the Asus A43SA bios with aptio MMTool. Hope someone finds it useful: http://www.sendspace.com/file/7ekefw

Sorry to resurrect yet another thread(on a different forum though), but triturbo's crazy projects always pique my interest . I am sorry to hear that you did not have much luck with the 550m gt project (though its impressive you got the card to POST). I recently got a romless toshiba hd 4650 to boot on a 5920g via sbios mod and you inspired me to go for the best mxm II card that could be created(that is the romless toshiba 4650 card with the 6770m core and eeprom=6730m). I searched high and low to find a vbios for the 6730m and i found a obsene laptop bios in a russian forum, and after disassemblying it with phoenix tool i came with this: Download 6730(2gb).ROM from Sendspace.com - send big files the easy way . This is the 6730m vbios, but for the 2 gb version. If some talented guys could compare this bios and the hd4650ddr3.rom bios and incorporate the needed mxm 2.1 stuff, we could have the best mxm 2.1 card ever WITH DIRECTX 11! I hope you have the courage to keep going for these crazy endeavors, you have been an inspiration for the modding community!
