Yes: * Start a fresh email thread * Give it a matching Subject line * Like "i486 stumbles on INT6, drops to shell" * Link http://lists.ipxe.org/pipermail/ipxe-devel/attachments/20220209/72374e7b/attachment-0001.jpg * Provide text of that "OOPS", to distinct 0,8 and 6 characters * Reread https://lists.ipxe.org/pipermail/ipxe-devel/2022-February/007497.html * Reproduce the INT6 on "bochs" or state that the INT6 is not triggered in "bochs" ( https://bochs.sourceforge.io/ ) * Chase the challenge and report about it > Cheers > Rich Enjoy converting the energy this email trigger into something good.
