Not according to that piece of architecture documentation that was quoted. www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/book.html#BOOT-BOOT0 It says that boot1 is used only with floppy boots. So, either the question remains or that oiece of doc is incorrect. Cheers, ////jerry > boot1 resides in first block of FreeBSD slice (or whole disk in dedicated > partitioning).
