Hi,
I successfully read/wrote a BIOS image file to a MSI Z390-A PRO (MS-7B98) motherboard via both Linux and DOS builds of flashrom based on the master branch on Jan. 1, 2021. Attached are reports/logs.
Also, I would like to report that the "buildbot archive" link for finding DOS bulids of flashrom linked on https://flashrom.org/Downloads is not working for me as I am not able to connect to that site (seems like https://buildbot.flashrom.org/ is no longer online).
So I built for myself a copy of flashrom for DOS. After making some changes to the code, I was able to cross-compile for DOS on Linux. I used pciutils 3.6.4, which did not require the patch to cross-compile the pciutils library for DOS. I put my build steps as well as my tested PC findings at https://github.com/HowardHo2021/flashrom-DOS-port.
Regards, Howard
