Thanks for this. It's next on my queue of patches to process. One thing I realised since we discussed this in IRC is that it needs to be generalised to be non-i386-pcbios-specific; in particular, __data16() and friends aren't allowed outside of arch/i386. I'll figure it out. Michael _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo/ipxe-devel
