The changes have already been tested on irc using virtualbox. ahci booting still works, and disk size of >2TB disks is properly reported. read/write >2TB not tested yet. will try to test tomorrow. However, others issues are outstanding: - intel partiton addon allows creating partitions beyond 2TB start/end, creating invalid partition table entries - gpt partition addon is readonly, can't initialize externally created partition with bfs. - mkdos can't initialize because B_GET_PARTITION_INFO failes. regards Marcus
