hi.  im trying to install freebsd 5.1 to my alpha's.  im new to all this but im pretty sure ive done things properly so im sort of confused.  here goes..
i downloaded the kern.flp and mfsroot.flp using an ftp client in binary mode.  i used brand new disks which i formatted freshly before using both fdimage and rawrite to write the images.  (i've tried this process about a half dozen times now.. )  each time i get an error that the disks arent bootable. (block 0 errors)  any ideas?   

thanks  J
