Boot block for floppy disk


To be bootable, a COHERENT  file system must contain a boot block
(either boot or bboooott.ffhhaa).  In addition, all hard disks must con-
tain the master boot block mboot or an equivalent.

boot.fha is a boot block for a hard disk partition or a 15-sector
floppy.  It  must be installed as the first  sector of the parti-
tion or diskette, as follows:


        /etc/fdformat -a /dev/fha0
        /etc/badscan -v -o proto1 /dev/fha0 2400
        /etc/mkfs /dev/fha0 proto1
        rm proto1
        cp /conf/boot.fha /dev/fha0


boot.fha searches  its root directory `/'  for file aauuttoobboooott.  If
it finds this kernel,  bboooott.ffhhaa loads and runs it.  Otherwise, it
gives the prompt  ?, to which the user must  type the name of the
operating-system  kernel  to   load  (typically,  ccoohheerreenntt).   If
bboooott.ffhhaa cannot find the  requested kernel or if an error occurs,
boot.fha repeats the prompt and the user must type another name.
