If your board is supported by flashrom internal flashing mode, you can
"recover flash" it internally if could boot to Linux. Any Linux
LiveUSB with iomem=relaxed added to Linux kernel parameters at GRUB
("e" button to temporarily edit this entry) would be sufficient: git
clone a flashrom repository and build it using the instructions from a
wiki. Or, even better, create a custom LiveUSB with it already
preinstalled. However, if not supported by a flashrom internal
flashing mode, then it's not currently possible.On Mon, Nov 4, 2019 at 3:16 PM Rafael Send <[email protected]> wrote: > > FWIW I'm currently running a Grub2 payload, which starts either Tianocore or > SeaBIOS from CBFS. > > Not a CSM and I think my coreboot has ACPI issues so I haven't actually been > able to boot Windows via SeaBIOS, but it does start and run Linuxes just fine. > > R > > On Sat, Nov 2, 2019, 00:54 Matt DeVillier <[email protected]> wrote: >> >> On Fri, Nov 1, 2019, 2:32 PM <[email protected]> wrote: >>> >>> Thankyou very much!
