Since today, the job is failing with an `could not load PC BIOS 'bios-256k.bin'` error thrown by QEMU. The version that causes this error is: https://qemu.weilnetz.de/w64/2021/qemu-w64-setup-20210203.exe#/dl.7z The previous version, which worked fine, was: https://qemu.weilnetz.de/w64/2020/qemu-w64-setup-20201124.exe#/dl.7z Both CI runs build the exact same code. You can find the full logs at https://github.com/rust-osdev/x86_64/runs/1908137213?check_suite_focus=true (failing) and https://github.com/rust-osdev/x86_64/runs/1900698412?check_suite_focus=true (previous). (I hope this is the right place to report this issue.) This is a known and documented problem with a simple workaround: "Known issue: currently requires start from installation directory or -L option to specify the location of the firmware files." And it is already fixed in the newer installer. See also the patch which will fix this issue upstream as soon as it was merged: https://patchwork
