Boot2 loading process

[Jan Pfeifer]

hi all,

I was reading through the architecture handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/book.html) about the boot process, and something strange caught my attention.

 According to the docs boot0 loads only the first record of the partition, that is 512bytes. But boot2 in my 4.11 freebsd has > 7K in size -- what makes sense, considering the amount of things it does and that it links btxld.

So my question is: where does the rest of the boot2 binary is located and how is it loaded ?

thanks in advance for any answers!

:)
