I would like to FTP everything that's needed to make CD with FreeBSD.
Since I never used FreeBSD before (only Linux), I'm little confused
with different directories and distributions on ftp.FreeBSD.org.

Not to say that there's more than 650MB of things there. :)

Can somebody list the directories which should be on FreeBSD 2.2.5
install CD?

It would be nice that CD is bootable, but that's not mandatory.

TIA

For the installation CD, it's not too difficult.  This kind of CDs is
probably the only one where what the El Torito specs call ``emulation
booting'' makes a little sense at all.  Just run mkisofs (version 1.10
or higher) with `floppies/boot.flp' as the argument for the boot
image, and it will take care for the rest.  You also need to specify a
file where it can store the `boot catalog'.  That's nothing you need
to worry much about, you can specify an arbitrary filename.  Take care
to use a filename that's not in use by anything else, or it will be
overwritten.  A common name is `boot.cat'; the name is (like the name
of the boot image) relative to the root of the CD-ROM filesystem.

For a generic bootable CD, it's quite more difficult.  There is some
code called `cdboot' in -current that allows you to create a bootstrap
for booting off an ISO 9660 CD, that is, boot /kernel, and mount the
CD as the root filesystem.  Due to the crappy specs this `El Torito'
stuff actually is, that sounds easier than it turned out to be.  Also,
be forwarned that this does only work on a minor number of controllers
and BIOS revisions; the only one i've got it to work was the AHA29xx
series from Adaptec, with their BIOS revision 1.23.  Later BIOS
revisions have broken basic CD-ROM IO support again, and other vendors
(like all the ``bootable ATAPI'' BIOSes i've seen so far) don't even
implement the required BIOS extensions to read a CD at all.  Even
Adaptec implements only half of the El Torito stuff, the (more
preferrable) non-emulation booting wasn't implemented at least in rev
1.23.  They promised me that it's been implemented later, but see
above: i haven't got rev 1.25 to support the BIOS Int 0x13 extensions
at all, despite of the menu item in the ^A menu.  Thus, cdboot still
uses the `emulation booting', where the emulated floppy image contains
just and only the bootstrap itself (7.5 KB, padded to 1.44 MB).

How can I make a bootable CD-ROM with FreeBSD 2.2.5 on it?

Folks, pleeeeease!  Mark your Cc's of Usenet postings as such.  I (and
i'm sure not only me) am sick of seeing posting in Usenet i've already
innocently answered in private mail.
