For a normal CDROM or network installation, all you need to copy onto
|
|
actual floppies from this directory are the kern.flp and mfsroot.flp
|
|
images (for 1.44MB floppies).
|
|
|
|
Get two blank, freshly formatted floppies and image copy kern.flp
|
|
onto one and mfsroot.flp onto the other. These images are NOT DOS
|
|
files! You cannot simply copy them to a DOS or UFS floppy as
|
|
regular files, you need to "image" copy them to the floppy with
|
|
fdimage.exe under DOS (see the tools/ directory on your CDROM or
|
|
FreeBSD FTP mirror) or the `dd' command in UNIX.
|
|
|
|
For example:
|
|
|
|
To create the kern floppy image from DOS, you'd do something like
|
|
this:
|
|
|
|
C> fdimage kern.flp a:
|
|
|
|
Assuming that you'd copied fdimage.exe and kern.flp into a directory
|
|
somewhere. You would do the same for mfsroot.flp, of course.
|
|
|
|
If you're creating the boot floppy from a UNIX machine, you may find
|
|
that:
|
|
|
|
dd if=floppies/kern.flp of=/dev/rfd0
|
|
|
|
or
|
|
|
|
dd if=floppies/kern.flp of=/dev/floppy
|
|
|
|
work well, depending on your hardware and operating system environment
|
|
(different versions of UNIX have totally different names for the
|
|
floppy drive - neat, huh? :-).
|
|
|
|
If you're on an ALPHA machine which can network-boot its floppy images
|
|
or you have a 2.88MB or LS-120 floppy capable of taking a 2.88MB image
|
|
on an x86 machine, you may still wish to use the older (but now
|
|
twice as large) boot.flp image which we also provide. That contains
|
|
the contents of kern.flp and mfsroot.flp on a single floppy,
|
|
essentially. This file should also be used as the boot file for those
|
|
mastering "El Torito" bootable CD images. See the mkisofs(1) command
|
|
for more information.
|
|
|
|
Going to two installation boot floppies is a step we definitely
|
|
would have rather avoided but we simply no longer could due to
|
|
general code bloat and FreeBSD's many new device drivers in GENERIC.
|
|
|
|
One positive side-effect of this new organizational scheme, however,
|
|
is that it also allows one to easily make one's own kern or MFS
|
|
floppies should a need to customize some aspect of the installation
|
|
process or use a custom kernel for an otherwise unsupported piece of
|
|
hardware arise. As long as the kernel is compiled with
|
|
``options MFS'' and ``options MFS_ROOT'', it will properly look for
|
|
and boot an mfsroot.flp image in memory when run (see how the
|
|
/boot/loader.rc file in kern.flp does its thing). The mfsroot.flp
|
|
image is also just a gzip'd filesystem image which is used as root,
|
|
something which can be made rather easily using vnconfig(8).
|
|
If none of that makes any sense to you then don't worry about it -
|
|
just use the kern.flp and mfsroot.flp images as described above.
