Early phase-0

====> 0. The installation process:

POS BIOS/ |-- isolinux boot monitor |-- stage-1: init |-- stage-1: loader `-- stage-2: a-installer

====> 1. stage-1/init and stage-1/loader are just from anaconda sources

$ make -C isys/ && make -C stage-1/

====> 2. Bootdisk creation: isolinux

bootdisk/ -- isolinux |-- isolinux.cfg -- splash.jpg

$ sh create-bootdisk.sh

bootdisk/ -- isolinux |-- isolinux.bin ==> just from tarball in binary format |-- isolinux.cfg |-- splash.jpg -- vesamenu.c32 ==> just from tarball in binary format

Note about vesamenu.c32:

com32/modules/vesamenu.c32 (graphical) com32/modules/menu.c32 (text only menu)

With vesamenu.c32 we can use a background image normally 640x480 pixels and either in PNG, JPEG or LSS16 format.

We can use the binary files from the native package of development workstation. In Fedora 10:

$ rpm -ql syslinux | grep -E "isolinux.bin|vesamenu.c32" /usr/lib/syslinux/isolinux.bin /usr/lib/syslinux/vesamenu.c32

====> 3. Bootdisk creation: initrd

First of all, we're going to use the native binaries of the development workstation (Fedora 10). Later, we'll use the built binaries from OE.

Note: loader binary dependences (in dev workstation Fedora 10)
