Slice Posted February 22, 2015 Share Posted February 22, 2015 Andy, I may say that this is really great work. Your BIOS 6450 is really universal for many cards confirmed by different users. Link to comment Share on other sites More sharing options...
Teo Nikolov Posted February 28, 2015 Share Posted February 28, 2015 Hi everyone. Great job on making such a good work so far. I have a question. My cousin has HD5570 OC by Gigabyte and I tried to add UEFI GOP to the rom using AMD UEFI GOP MAKER, but my PC is giving me DLL errors. I currently don't have MAC, since my new LAN card is not supported (IC PLUS). I'll really appreciate any help figuring out if it can be done. Here's link to the card's rom at techpowerup.

Riley Freeman Posted March 16, 2015 Share Posted March 16, 2015 Thanks Andy! Updated my 210 and it's all good. The previous efi rom worked fine but might as well have the newest So you reckon this rom will work on any 200 series card? Should be handy for anyone with a 260 as that card is listed in AppleGraphicsPowerManagement.kext (there was a 260 Mac Edition but it never shipped).

VOT Posted March 16, 2015 Share Posted March 16, 2015 Hello, I have no idea what I'm doing, I would like my non-GOP VTX3D GDDR5 Radeon HD 7750 to be flashed to GOP ROM, and apparently this is the place to do it. I am on Windows, and v4 doesn't seem to be working for me and spitting out lots of errors. It did give me an output ROM, but I don't think I did it right. Can anyone give a small tutorial if that's not a problem? Thanks, VOT. Link to comment Share on other sites More sharing options...
Riley Freeman Posted March 17, 2015 Share Posted March 17, 2015 I tried running the v4 script from Windows and it doesn't work (command not found errors). If you have access to a Mac it will work fine there. I downloaded the rom from here and was able to make a GOP bios. I've attached it here along with the terminal output (as log.txt). Make sure the BIOS I downloaded matches your card and then see if you want to risk flashing it. Also make sure you have a way to flash the original BIOS back in case it doesn't work. There's always a danger when flashing modified bios files. If your card BIOS differs from the one I downloaded attach it here and I'll use that instead.

VOT Posted March 17, 2015 Share Posted March 17, 2015 Unfortunately, AMD Winflash said it couldn't find the VBIOS Edit: GPU-Z is now working and saving the BIOS properly. I deleted the ATI Winflash attachment and attached the GPU-Z BIOS. Thanks for your help by the way, I didn't think anyone would help me.

VOT Posted March 17, 2015 Share Posted March 17, 2015 Unfortunately it didn't work, I tried both ROMs under ATI Winflash and ATIFlash, both said the ROMs were invalid. I've noticed that my original BIOS is 128kb, and the BIOS you make is 120kb. Could that be a problem? Link to comment Share on other sites More sharing options...
Riley Freeman Posted March 17, 2015 Share Posted March 17, 2015 It might be a problem with the ATIFlash versions. Are they up-to-date enough to support uefi roms? I've only done this with my nvidia card so I don't know how it works on the ATI side. Your original rom was 128kb but exactly half of that was padding. The script strips this out, leaving a 64kb rom which is then stitched together with the UEFI rom. If you manage to get it flashed, I'd suggest booting normally first to see if the legacy bios part of the rom still works ok. Then you can try activating the uefi side in the system bios. If that fails you'll know that resetting the system bios will get you back up again. In case it is a filesize thing, I've padded out the rom to 128kb. See if that makes any difference. 1002.683F.rom.zip 2 Link to comment Share on other sites More sharing options...
VOT Posted March 17, 2015 Share Posted March 17, 2015 Unbelievable It worked! I have a GOP graphics card! Thank you so much for your help, without your help this would have been impossible. Your other BIOS would have probably worked, but it's the -f (force) flag in ATIFlash that made it work. Link to comment Share on other sites More sharing options...
Riley Freeman Posted March 17, 2015 Share Posted March 17, 2015 Awesome It's great that we can do this. Gives older cards a new lease of life in the UEFI world. 1 Link to comment Share on other sites More sharing options...
Simonej Posted March 18, 2015 Share Posted March 18, 2015 Gigabyte GT210 - NVFlash error: EEPROM size too large Thanks Link to comment Share on other sites More sharing options...
Riley Freeman Posted March 18, 2015 Share Posted March 18, 2015 Run "nvflash --check" to see what size your card's eeprom is. Mine is 1024Kx1S meaning it can take a rom file up to 128kb in size. Some models of Gigabyte cards didn't get UEFI rom updates, so perhaps they don't have large enough eeproms to hold the larger rom needed. Link to comment Share on other sites More sharing options...
Simonej Posted March 19, 2015 Share Posted March 19, 2015 Thank you Riley, mine is too 1024 but new rom is 168kb (i think).

Riley Freeman Posted March 19, 2015 Share Posted March 19, 2015 Looks like your original rom already supports UEFI so there's no need for you to patch it. If you've been unable to get it to work your board might not support "fast" UEFI boot (my Z68 can't). Link to comment Share on other sites More sharing options...
Simonej Posted March 20, 2015 Share Posted March 20, 2015 Yes, I confirm, my computer already boot with CSM disabled, but it take long time to power on (the first time). Anyway thank you for your support and thanks to Andy for software! Link to comment Share on other sites More sharing options...
AelpirT Posted April 13, 2015 Share Posted April 13, 2015 Hello. Thanks, first, for all the effort everyone is putting into this: I've spent a few hours reading the various posts and trying things out and I have learned quite a bit! Unfortunately, I have not learned enough to "roll my own". At least, not 100% successfully... :-( Part of the problem is probably that most forum attachments do not download for me, for some reason. Maybe because I just joined...? But the error message does not indicate that. Another issue, I expect, is that I do not have a Mac so the scripts I managed to get (DropBox links work!) are not applicable. Even the Maker v4 script which's supposed to run on Windows is complaining about missing tools: grep, etc. So my last resort is to hope that someone might be able and willing to help! A summary of my situation: I have a couple of video cards and I would like to get both or either of them working with UEFI GOP: * XFX Radeon HD 6850 (HD-685X-ZNFC). * ASUS GT 640 (GT640-DCSL-2GD3). Their BIOSes are here. I have tried to get a BIOS from ASUS without success. And the XFX is really too old to expect any effective support for it; so I didn't even try to ask them. I did, however, try to manually make a BIOS for it using UEFI modules I found attached to the 6850 BIOSes posted here. I first tried the 6850 BIOSes already there (Gigabyte doesn't POST. XFX and PowerColor require CSM). I then tried to create my own BIOS using the UEFI modules from them and the legacy module from the original BIOS; but again the results required CSM... :-( And this is where I am right now. Any help, pointers or ideas would be very appreciated and most welcome! And thanks for reading this far... :-) Edit: Hmmm... I seem to have managed to get a functioning UEFI GOP BIOS for the 6850 concocted using the UEFI module from this post. So that's less urgent, now. In fact, everything is so much less urgent, now! Though I would still very much appreciate any help as I would rather get my GT 640 and its quad-monitor output support working. Edit: Success at last! UEFI GOP firmwares for both of my cards are now included in the DropBox shared folder linked to earlier. Maybe they'll be of some use to someone. And hopefully they'll save someone the pain of dealing with ASUS tech support; the most incompetent support team I have had the displeasure of dealing with in my ~20 years in IT: it took them 26 days to check their own website and tell me they have nothing but what's on there, even though I clearly pointed out that I already checked the site. Naturally, the files are provided without warranty of any kind, etc. 1 Link to comment Share on other sites More sharing options...
once375ml Posted April 23, 2015 Share Posted April 23, 2015 Someone from pcbeta.com have made a UEFI GOP VBIOS by using AMD-UEFI-GOP-MAKERV4 for me. My “6770” is 5770 with two “MCuC”s, so the second MCuC will be overridden by 6450GOP. This will lead to a fail cold start. SO, I insert the second MCuC to the end of VBIOS made by MD-UEFI-GOP-MAKERV4, and modify the offset indicating the second MCuC Anyone can check my modified bios? I don’t know if my mind and steps are right and I don’t know how to fix checksum my modified bios is 140K I will replace onboard M25P10(128K) to M25P20(256K), if my bios works I will flash it into M25P20,which is big enough, if it don’t work, original bios still can be flashed into M25P20 6770.zip attach_MCuC.zip Link to comment Share on other sites More sharing options...
once375ml Posted April 24, 2015 Share Posted April 24, 2015 I finally make a working 5770 rom (Resolution works without black borders, full uefi boot without cms support) but rom works only 1 time. i can reboot many times without any problem but if shutdown the computer 5770 never comes again until reflash it with original rom. After searching about my rom i found many posts from netkas about MCuC instance in this rom. Maybe that rom needs different modding from others card. Anyone ant idea? Maybe i found the problem: After reading netkas notes about 5770-5870 and 4xxx roms i note coz MCuC instance must be 2 times in rom 3a. Move the mcuc section (last part of the BIOS) to make room for the EFI.At this stage you can trash the modified myrom.rom that only has one "MCuC". Open the original myrom in 0xed. Scroll down to the end, it should show a long string of "F". Select a large part of it. Cut. Look for "mcuc" (text search field) and locate the 2nd instance, near the end of ROM. Note its offset, as indicated at the bottom of the window. It should be 1A000 (hex). You can switch between decimal and hexadecimal by double clicking on the "dec" or "hex" text on the bottom left. Upward "mcuc" is a long string of "F" where the EFI should be inserted. Put the cursor anywhere in that string. Switch to insert mode ("edit" menu) and paste. Note the new offset of "mcuc". If the offset hasn't changed, or if you have lost the 2nd instance of mcuc, close the ROM without saving and do these steps again. Save a copy of myrom.rom (with this name) in your home directory.Then redo steps 2a and 2b. If only one instance of mcuc found, you're screwed. You cannot make a custom ROM with your original BIOS.After that must set the new offset of MCuC on first MCuC instance: If 2 instances are found...3b. Correct the new offset of mcuc in myrom. Say it has changed from 1A000 to 1A200 (if you have pasted a 512-Byte string of Fs). In 3 Bytes, this new offset is written 01 A2 00. In BIOS code, bytes are written backwards: 00 A2 01. To find where to indicate this offset, locate the first instance of mcuc. 8 Bytes upward (16 chars) you should see the original offset 00 A0 01. Go to overwrite mode and replace this with the new offset. Save myrom.rom in your home directory.After that must fix checksums and indicator (using fixrom.py).The problem of all that is not enough space exist for 2 MCuC instances and uefi, rom file goes 140kb. I cropped the last lines of 2 MCuC instance but im not sure if that works. I will checked home and i will report back. If finally that works i will edit your script for 5770 support. UPDATE: UEFI BIOS isnt possible to works on 5770 because 5770 rom not have enough space to keep UEFI. 5770 BIOS: 62.904KB MCuC Table: 22.944KB UEFI: 59.849KB 5770 BIOS SIZE: 128kb UEFI+BIOS+MCuC= 145.697KB (MCuC table is code for GDDR5 Initialization) Would you plz make a lager 6770 ROM for me i will replace EEPROM See thread above Link to comment Share on other sites More sharing options...
eeansa Posted May 14, 2015 Share Posted May 14, 2015 Thanks for the great thread and information. I just registered to site to be able to download links, even after registering I'm not able to download anything (other than dropbox links). Any ideas?

Intel478 Posted June 26, 2015 Share Posted June 26, 2015 You need this little tool which I just uploaded. Dump your VBIOS, put in roms directory. Run script. Flash under Windows with NVFlash. Reboot, enjoy UEFI GOP EDIT: But please be careful, there are many models of the GT210, wrong model might make card useless... Thanks a lot in advance for this awesome tool and your help! When I run it under ArchLinux with jdk7 and latest python installed, I get: cannot execute binary file: Exec format error File "fixrom.py", line 100 print "Usage: %s <infile> <outfile>\n" % sys.argv[0] SyntaxError: Missing parentheses in call to 'print' Your 'new' UEFI rom is ready at uefi.rom Edit: after fixing the parenthesis myself I run into this one: cannot execute binary file: Exec format error File "fixrom.py", line 103, in <module> f=file(sys.argv[1]) NameError: name 'file' is not defined Your 'new' UEFI rom is ready at uefi.rom Edit2: after replacing file with open for python v3, I get this error: cannot execute binary file: Exec format error File "fixrom.py", line 103, in <module> f=open(sys.argv[1]) FileNotFoundError: [Errno 2] No such file or derectry: 'uefi.rom' Your 'new' UEFI rom is ready at uefi.rom Edit3: It looks like that ./Efirom simply does not run on my x64 system, while it should: EfiRom: Mach-0 64-bit x86_64 executable. Edit4: Nevermind, I now see that Mach-0 is of course a Mac executable, not linux. Edit5: A friend used converter version 2 for me, and the atiflash tool under dos starts but doesn't give output on the cmd line. Can you please convert my rom for me? I put it here: http://www.filedropper.com/100268d8 My card is a 0x68D8 from Sapphire btw. Edit6: AMD v1 tool worked for me! Succesful flash and non-CSM UEFI support now! Edit7: After a cold reboot the screen remains black... how to fix this? (besides orig rom flash) Edit8: The card seems bricked. Atiflash and ati-win-flash both do not recognize the card being present in the system at all. Is there another way to overwrite the VBIOS back to original? I have made a backup of the rom of course.
