Mirone Posted August 22, 2014 Share Posted August 22, 2014 I have a EVGA Geforce GT620, 2GB is there any possibility to fix her? Link to comment Share on other sites More sharing options...
Riley Freeman Posted September 4, 2014 Share Posted September 4, 2014 It would be great if this allowed me to get a GOP bios on my GT210 some day. I had a look on the Gigabyte site and they have a UEFI BIOS for one of their 210 cards. I was able to extract it with andy's UEFIRomExtract tool but I'll wait until some more progress is made with nvidia cards first. Link to comment Share on other sites More sharing options...
JorgeMax Posted September 12, 2014 Share Posted September 12, 2014 STLVNUB I set my bios to boot into "Windows 8" system and appeared to "CSM" option. Put to "Disable": 140825220415.BMP The boot was on the clover native resolution of the monitor without the EFI driver "CSM" so Clover. Now my video card is running in UEFI mode with DVI-I and VGA ports with no problem. Next step is to test with the Bootloader "Ozmosis", but only when it is supported video cards from AMD and allow changing the "framebuffer".

JorgeMax Posted September 13, 2014 Share Posted September 13, 2014 Does fast boot work? I suspect it won't as bios is not signed. I saw no difference in startup speed. The only difference is the resolution of the clover boot screen, which was the native resolution of the monitor. I had not before, the resolution was 1024 x 768 The "CsmVideoDxe-64.efi" driver was causing problems on ports DVI + VGA. Link to comment Share on other sites More sharing options...
KonstantinosNks Posted September 14, 2014 Share Posted September 14, 2014 (edited) 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: 62.904KBMCuC Table: 22.944KBUEFI: 59.849KB 5770 BIOS SIZE: 128kbUEFI+BIOS+MCuC= 145.697KB(MCuC table is code for GDDR5 Initialization) original.zip uefi_rom.zip UEFI_2MCuC_full.rom.zip UEFI_2MCuC_128kb.rom.zip Edited September 16, 2014 by KonstantinosNks Link to comment Share on other sites More sharing options...

jamiethemorris Posted September 15, 2014 Share Posted September 15, 2014 on my R9 270 i had no "black borders" even before using UEFI-GOP-Maker to create a gop rom Yeah it seems to be either specific to the card or the display. My 6670 has black bars on my tv. I've never tried it on any other display though. Every other card I have never had any black bars. Link to comment Share on other sites More sharing options...

leatherman Posted November 16, 2014 Share Posted November 16, 2014 I used atiwinflash and had no problems. My card is only displaying with hdmi out on boot so you might want to check that if you're using dvi. Link to comment Share on other sites More sharing options...
wastez Posted November 28, 2014 Share Posted November 28, 2014 I used atiwinflash and had no problems. My card is only displaying with hdmi out on boot so you might want to check that if you're using dvi. No it´s not the output, it´s related to GDDR5 init. (mcuc) Because it´s working after restart but if a cold boot is done it isn´t working anymore because the GDDR5 isn´t able to initialize. Do you have a 5770? It´s hard to imagine for me. If you have one it wouldn´t be enough to use this tool. Link to comment Share on other sites More sharing options...

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...

RCornell Posted December 14, 2014 Share Posted December 14, 2014 Hi Andy, Could you, please post a link to the working Windows version of the script? Have any of you guys here managed to successfully flash a dual GPU card with UEFI GOP? I have a XFX 6990 BE. Any help will be appreciated. Have a great one! Here's your BIOS, but you have to flash 2 BIOS because your card four BIOS , 2 backup, and 2 cards used for its operation. Please note that a BIOS master, and the second slave!!! It is very important!!! Consult with someone how to flash the BIOS, so that would not have been reversed master with slave!!!
