FreeBSD/i386 5.4-RELEASE Release Notes

In prior FreeBSD releases, the disc1 CD-ROM (or ISO image) was a
bootable installation disk containing the base system, ports tree, and
common packages. The disc2 CD-ROM (or ISO image) was a bootable ``fix
it'' disk with a live filesystem, to be used for making emergency
repairs. This layout has now changed. For all architectures except ia64,
the disc1 image now contains the base system distribution files, ports
tree, and the live filesystem, making it suitable for both an initial
installation and repair purposes. (On the ia64, the live filesystem is
on a separate disk due to its size.) Packages appear on separate disks;
in particular, the disc2 image contains commonly packages such as
desktop environments. Documents from the FreeBSD Documentation Project
also appear on disc2.

(o instalacnim DVD jsem v zivote neslysel, takze vychazim z predpokladu,
ze to bude CD1, pripadne CD1 a neco navic)

Smazat MBR (v prekladu: nahradit "cistou verzi", to dela prave
fdisk /mbr), nastavit v biosu bootovani z disku, kde je OS. Problem
vyresen.

PS: Mozna by bylo vhodne se pripravit i na fakt, ze problem vubec nebude
v MBR. Nevim samozrejme, na cem je tento predpoklad zalozen, takze to
nerozvadim dal.
