P.S. this will make your card ident as 7950 in system report, but that's cosmetic, won't cause you any issue. If you want it to ident as 280X, you have to hex edit the rom image by yourself. That's already covered in the first page.
4) should be put in between 1) and 2) or your card may not work
Read through the entire thread and count the number of complaints in regards to your 'proper and stable' comment then draw your own concussions.
ATIFlash is simple and works, it's mentioned throughout the thread.
Pretty much all your questions are answered by reading the ENTIRE thread
Main issue with new cards is when they only have a single MDP or DP. These are for most part unusable.
I've spent the last hour combing through post-by-post looking for one.
UPDATE: ok, found one. Appreciate you egging me on to keep looking.
The ROM I made from your work is attached in case it helps others. Thank you so much!
The card I used:
MSI RADEON R9 280X GAMING 3G (TWIN FROZR IV, OC EDITION)
part number 912-V277-067 (on box)
EAN 4 719072 314026 (sticker on card)
UPC-A 8 24142 01599 5 (sticker on card)
Information on the EBC firmware attached here:
Subsystem ID: 0x2775
Device ID: 0x6798
PC BIOS (stock as shipped): 113-MSITV277MS.350 TAHITI B0 XTL C38650 GDDR5 3GB, BIOS Version 015.041.000.000.003435, ROM Revision 113-C3865001-TU5
Mac EBC EFI: (replaced stock UEFI): ATY,Hamachi, ROM Revision 113-E2080C-101, EFI Driver Version 01.00.624
Can anybody help and modify my original legacy bios ???
Thank you for the help. I've flashed the BIOS on my MSI R9 280 card with the ROM that Mr. Zarniwoop provided and it works great. Boot screens come up as hoped/expected.
I did go ahead and do the R17 resister removal as well, and am now receiving the 5.0 GT/s PCIe speed -- again, as hoped/expected.
I think I'm all set - thanks again.

Thanks kennyman, I'm already successfully running 351 with EFI support for bootscreens, as mentioned above.ok, I have the same card. Please post your card.rom, mine is using Elpida memory.
I have attached 351 from your link, please try it. You need to change .zip to .rom
