Hi,

I accidentially ordered a Sata SSD disk which diskinfo reports a 
sector-size 4K instead of 512 bytes. Trying to get it to boot under 
FreeBSD appeared impossible. Then I started looking into the boot0,1,2 
and loader and the assumptions they make about 512 byte sector size LBA :-(

Anyone has any recommendations or experience about how to use native 4K 
disks with FreeBSD?
