[Request] Unlock "Advanced" and "Chipset" tabs on Samsung All-In-One DM500A2J

[dyang94]

Hi I wish to unlock the first and second "Advanced" tabs and "Chipset" tab on Samsung All-In-One DM500A2J-K26L computer to see if I can get EXP GDC to work on mPCIe. I've extracted the rom with Afuwin, and I've tried to change Default to User/Supervisor, but that did not work. I've Googled this kind of Samsung BIOSes and there are not many results, but all first tries have failed but second succeeded.

Hi!

Try this mod and response the result.

Thanks, genius. Your username says it all!
There are no rectangular images with setup option names because I assume these options don't have their own images when they are not supposed to be available, but I can select them with keyboard. Here are the images.
May I ask how you did it?

1.Sorry ,thees screenshots are so small to watch ,could you make some large image again and upload them?
I'm gonna plan let three tab Advanced ,Chipset , and boot appear in the bios screen ,but it seems it lost a original tab??

2.I guess that official wouldn't to design image button for these lock tabs ,so you only can see a invisiable button.


3. Navigate to new Boot tab > CSM parameters , option "Other PCI device ROM priority" and "Boot option filter" ,i think they should be useful for your demand.

Okay , now test this mod again.

I've uploaded full sized images. Just to let you know, Primary Graphics from Auto to IGFX, enabling IGFX makes EXP GDC work! on macOS but not on Windows. Can't automatically find and download driver for GTX550TI lol
Sorry for being confused XD but what did you mean by "my demand"? Is it how to edit the afuwin.rom or is it showing the buttons?

Edit: did not see the second reply. I'll test soon!

Yes ,this result is i expected ,but it seems doesn't link image button to new unlock tab.
My idea is that there are two same name tab "Advanced" and "Boot" ,i guess if we hide stock advanced tab and boot tab ,maybe image button would link to new tab ,but it was not the case.

Now you can re-flash bios to version 1 bios.

Advanced button clicks to New Advanced settings. I think using the green Boot button for the new hidden Boot tab would be the last thing, but I can live with this. Thanks!
