This conversation from irc explains where that strip.rom file comes from. <tulphoon> Hello. I've extracted ROM file from my card and i would like to apply UEFI "patch" to it. How should i do it? I don't want to use nvflash directly on the card. <tulphoon> My card is MSI GTX 660, and i've got the "patch" file from this thread https://forum-en.msi.com/index.php?topic=274331.0 <tulphoon> Basically i want to merge the two files (if that's even possible) and have single EFI compatible file in the end. <tholin> I see no mentioning of "patch" in that thread. It looks like just a .rom file. Use that rom instead of the one you dumped. <tulphoon> That one doesn't qualify as rom tho. <tulphoon> at least, EfiRom -d throws out error: 3001 <tholin> looks like you are right, it's some metadata format <tulphoon> but i don't want to nvflash it tho. <tulphoon> Unless that's the last solution <tholin> the real vbios is embedded in it. It starts at byte offset 1536 and I suppose it's 128K big like most vbios. <tulphoon> probably the nvflash thingy is able to strip the thign and make it work. <tulphoon> the thing* <tholin> try running this on it "dd if=NV287MH.2K0 of=strip bs=1 skip=1536 count=131072" <tulphoon> okay, gimme a sec. <tholin> the vbios rom-parser can parse the resultant file <tulphoon> holy fuck <tulphoon> you are a genius sir. <tulphoon> wait. <tulphoon> Okay, the rom is working and has EFI support. <tulphoon> but i'm still getting Code 43 on my Win 10 VM. <tulphoon> I'll investigate further tomorrow though. Huge thank you for help tholin :) <tholin> np Perhaps the real rom is larger than 128K? That seems unlikely. At least you can recreate that stripping and get the same rom. _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
