\033[1mNotes.\033[m\017

This script will guide you through the installation of the 2005.1
or 2005.0 editions of Gentoo. It is assumed that you have the
relevant CD sets, but no internet connection.

This script will use the pre-compiled binaries found on the packages 
CD. It will get a Gentoo system up and running quickly, so that you 
can experiment with a working Gentoo system (and, in particular, its 
package manager, portage).

When the script pauses, you should enter the requested information,
or press return, to continue.

This key is usually the Del key. If the Del key does not work, look
around the boot screen page to try and discover the correct key. It
is usually one of the following:

Del, F1, F2, F3, F10, Ctrl+Alt+Esc, Ctrl+Alt+A, Ctrl+Alt+S, or Esc.

\033[1;46mless $official \033[m\017

This will display the official documentation. Read it. Note that
Alt+F3 brings up a third virtual terminal, Alt+F4 a fourth, etc.

\033[31mThe official documentation contains instructions on how to partition
your hard-drive. The instructions use fdisk (cfdisk is better if you
are familiar with it). You need to run fdisk from one of the virtual
terminals (Alt+F3) or, you can exit this script by pressing Ctrl-C,
run fdisk, and then restart the script with /a/walkthru1.\033[m\017

You should create and format at least two partitions on your hard-disk.
One, a smaller partition (about double the size of your RAM), for use 
as swap, and another to install Gentoo on. You may also wish to create
a boot partition, but we will not bother with one. If you have a lot of
RAM, then the swap partition is probably not necessary either. It is
recommended that you reboot after having formated your partitions.

I suggest that you format your partitions with the Reiser filesystem
(rather than ext2 or ext3). It is an excellent filesystem. XFS and
JFS may also be fine, but I have no experience with them.

The official documentation is (deliberately) wrong in a few places.

run your system, just fine. It also often loads many unnecessary modules

Your own kernel will be leaner and meaner, but it takes some knowlegde 
of your system to choose all the drivers and features you desire. 

You will often have to roll your own kernel if you wish to include non
standard features, eg, squash or cloop filesystem support.

It is not easy to configure a kernel (mainly because you will not be

devices. So all the modules have been hidden (the boot message claims
the modules are loaded). This may have been acheived by rewriting the
archiving program cpio, so that choosen files can be hidden. Perhaps,
Gentoo is not really all about helping people learn Linux, after all.

# 1). Partition the hard-drive, creating a small swap partition.
# 2). Format the partitions.
# 3). Copy the scripts walkthru1 and walkthru2 to a floppy disk.
# 4). Enter the BIOS and set the CD-drive as the first boot device.
# 5). Start your computer.
# 6). Mount the floppy drive with the commands:
# mkdir /a
# mount -t vfat /dev/fd0 /a
# 7). Check the scripts are executable and run the first by entering:
# chmod +x /a/walkthru*
# /a/walkthru1
#--------------------------------------------------------------------
# To start this script enter:
# /a/walkthru3

Initially, after \033[31memerge --usepkg kde\033[m\017 led to all sorts of problems,
I thought that Gentoo 2005.1 did not support KDE. It does. It seems
the new command is \033[31memerge --usepkg kde-meta.\033[m\017 Who would guess that!?!?
Gentoo didn't bother to tell anyone about the change until it was made
public on their forums (after which they added the command to their
KDE page, but not to their installation instructions (as yet)).
The forum admins deleted this information by moving it to some hidden
corner of their site (with the excuse that it had been dealt with in 
some other deliberately hidden away post). The forum still has this 
information \"safely\" hidden from public view.

file from another linux installation (on the same physical hardware), you
should be able to copy it to /etc/X11/xorg.conf and it should work. You 
may have to tweak it a little. Whatever you do, do it with care, as it is
possible to total your graphics card, and/or monitor.

If you do not have a working xorg.conf file, you can find out what sort 
of graphics card/chipset you have by entering
 
\033[1;46mlspci \033[m\017

and looking for the VGA entry. The command lspci lists vendor and
model information about all your PCI and AGP cards. "
read m
echo -en "\nFor more on setting up graphics, see; 
http://www.gentoo.org/doc/en/xorg-config.xml

There are various tools to help you setup your graphics configuration,
for example, \033[31mXorg -configure\033[m\017 or \033[31mxorgconfig\033[m\017 or \033[31mxorgcfg\033[m\017. Since I have
little experience with these, I will leave you to read the docs.
 
Once you have your xorg.conf file configured, you can start xfce4 with
\033[34mstartxfce4 \033[m\017

Starting gnome is a bit harder. For Gentoo 2005.0 you need to add the line
\033[34mexec gnome-system\033[m\017
to the file ~/.xinitrc (in your home directory (I believe you need to
create this file)) and then enter the command
\033[34mstartx\033[m\017
However, this does not work for Gentoo 2005.1. Thanks a lot, Gentoo.

To start KDE, comment out/remove the line \033[34mexec gnome-system,\033[m\017 and write
\033[34mexec startkde\033[m\017 for Gentoo 2005.0 or
\033[34mexec /usr/kde/3.4/bin/startkde\033[m\017 for Gentoo 2005.1,
to the ~/.xinitrc file and then enter the command
\033[34mstartx\033[m\017.
