I found a link to correct the problem that many people have but no one has completed with flashrom on Mac they e 580 from Mac Pro then insert to PC to use flash program, I would like to try to do all on MAC usin flash rom. I was able to complete install brew then flashrom but now am overwelmened by manual here is the link with fix https://forums.macrumors.com/threads/turn-a-new-sapphire-rx580-pulse-into-t… I need arguments to dump rx580 ROM to file copy to backup edit changes save file flash rx580 card What args should I use to dump to file and then flash

Kaby Lake R - not detecting chip & size correctly
by Rafael Send 27 Aug '19

27 Aug '19

Hi there- I'm running a custom Thinkpad X210 motherboard, which has a Kaby Lake R on it. The default flash chip is 8MB, and is detected as "Opaque Flash Chip" with the correct size, and it flashes correctly. It's an MX25L64 When I replace it with a larger chip (32MB in this case), the detected chip is still the same as before (Opaque flash chip, size 8MB) but the new chip is a MX25L256. This actually works out great for using the same old images and swapping between chips, but I can't flash anything bigger if the size isn't detected correctly so it defeats the purpose of what I'm working on. What can I try to get the chips to be detected correctly? Alternatively, are there any logs or messages I can collect that would help folks on this list add chips or debug this? Thanks, Rafael

BIOS Update
by Shaver,Zachary J 16 Aug '19

16 Aug '19

Hey, I'm considering using flashrom to upgrade the bios on a MSI B450M Pro-M2 Motherboard. It's BIOS ROM appears to be a MX25U12873F but I only see MX25U12835F in the supported chips for flashrom. I did a cursory comparison of the datasheets for the two and they look very similar. Is there a chance I could flash the 73 with the 35 profile in flashrom? I am aware that they are 1.8V and will need a 1.8V supply and 1.8V gpio from the programmer (in my case raspberry pi). Thanks

Copy / backup ENTIRE flash chip; does "-r" already do this?
by Rafael Send 15 Aug '19

15 Aug '19

Hi there- I'm looking at swapping out the physical flash chip on my machine for a larger capacity one, so I wanted to get a quick sanity check: Does a flashrom -r pick up all the various regions in the chip, or does it only go after the BIOS region if I don't specify a layout file? I.e if I do a flashrom -r on the old chip then flashrom -w on the new one, will I get an identical copy of the entire thing? Thanks and apologies if this can be found in the documentation, please feel free to point me there instead. Rafael

However, we will add the new names to the in-program (and hence wiki) database so that this new information becomes public. Thanks for the heads up, Victor. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Re: lenovo c540

You need to extract a clean BIOS ROM ( "clean" = without any system-specific settings ) from a BIOS update utility. Try to open this utility (called something like "winflash_3.00.exe") as an archive with 7zip, and extract the contents of this .exe file using 7zip. If successful, it would give you a set of files, one of which might contain this clean BIOS ROM. Could be called something like WinVALGC300.bin ( you could guess it by looking at the file sizes ). Then open this file using a hexedit, search for $_IFLASH_BIOSIMG header. Not directly after but slightly further after this header, at the closest address ending by 0 (rounded by 0x10) there is a start of BIOS section, the size of which should be equal to a size of your BIOS chip. Copy-paste it into a new binary file, then you could try using it (but only after making a backup of your current chip contents!). You could also compare the contents of your original ROM image vs this "clean" image, to get an idea where a password might be stored (could be encoded instead of a plain text).
