Advice: Make it an interesting challenge Reproduce the "problem" on qemu. AFAIK has qemu both "BIOS" and "uEFI". [0] Then describe how others can reproduce the challenge. In other words: Go beyond "It doesn't work on _my_ hardware!" > Dean. Groeten Geert Stappers [0] It will gain original poster a faster development cycle. -- Silence is hard to parse _______________________________________________ ipxe-devel mailing list ipxe-devel@lists.ipxe.org https://lists.ipxe.org/mailman/listinfo/ipxe-devel
