boot.fha Device Driver boot.fha
Boot block for floppy disk
To be bootable, a COHERENT file system must contain a boot block
(either boot or boot.fha). 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 autoboot. If
it finds this kernel, boot.fha 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, coherent). If
boot.fha cannot find the requested kernel or if an error occurs,
boot.fha repeats the prompt and the user must type another name.
