Hello Sorry for the incident : my commit on multiboot support for amd64 broke biosboot. The offending change was sys/arch/amd64/conf/kern.ldscript 1.27-1.28 I reverted it in sys/arch/amd64/conf/kern.ldscript 1.28-1.29 amd64 biosboot should work again with 1.29. -- Emmanuel Dreyfus manu%netbsd.org@localhost
