A bootable disk contains an OS-specific boot code. It is not a regular file.
Also there is partitioning information on the disk, and this is not a regular file either.
The frame where files are stored in is called a filesystem. Microsoft DOS only understands FAT filesystem, Windows understands FAT and NTFS filesystem. But SCO-Unix certainly uses a different file system. Linux understands many filesystem types, maybe the one from SCO-Unix.
You all-files backup will miss the boot code, the partitioning information, the filesystem.

The BIOS on an X86 PC requires the disk to have an MBR, master boot record. This can contain the boot code, or contains code to find another boot code block (that in turn can find another boot code).
My knowledge ends here. Look at Wikipedia. Hope that other guys here know more...

boot.config
BOOT.CONFIG(5) BSD File Formats Manual BOOT.CONFIG(5)
NAME
boot.config -- Configuration file for the boot blocks
DESCRIPTION
The boot.config file contains options for the FreeBSD boot block code.
When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are
missing an ``a'' partition require user intervention during the boot process). If the boot.config file is found, its contents are used as
the default configuration options for the boot block code and are echoed to the system console.
A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other
valid boot(8) option on a single line, as it is done at the ``boot:'' prompt.
The options related to the boot image selection described below and all the other options available for boot.config are documented in detail
in the boot(8) manual page.
FILES
/boot.config parameters for the boot blocks (optional)
EXAMPLES
The command:
# echo "-P" > /boot.config
will activate the serial console of FreeBSD.
The command:
# echo "1:ad(1,a)/boot/loader" > /boot.config
will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk.
The command:
# echo "1:ad(1,a)/boot/loader -P" > /boot.config
will do both of the above.
