><P
> Below we will be asked about what partitions to make. We
should have at least these partitions:
<P
></P
><UL
><LI
><P
> A PReP partition. It should be the first primary partition
on one of the SCSI drives, preferably the first (this
naming the partition to sda1). It must have type PReP boot
(type 41), and must be large enough to
hold a compressed Linux kernel image (zImage). Something like
5-10MB should do.
</P
></LI
><LI
><P
> A swap partition. It can be either a primary or a logical
partition on any drive. Any size will do, but a guide may
be twice the size of you physical RAM. I have 64MB RAM, so
I have a swap partition on 128MB.
</P
></LI
><LI
><P
> A system root partition. It can be either a primary or a
logical partition, and it should be big enough to hold the
main parts of the installation. You should write down the
device (disk and partition number, like sda5, for example)
for your system's root partition. You will need it later.
The easy way is just to use the rest of the harddisk space
for this. If you have several harddisks, big drives or
special requirements on safety and other things, you
should consider to make own partitions for /home, /usr,
/usr/local, and other parts of the system. Details on this
is outside the scope of this document, but there is a
good discussion on this in the Linux Partition HOWTO.
</P

</P

system as you may wish, but this is the very minimum.
</P

by pressing F5 (or F6) at the bootscreen while the check icons pop
up in the bottom of the screen. After a while, the screen blanks
out, and Linux will boot. At this point, you can shout a little
"hooray" for yourself, if there are not too many in the room,
and Tux, the Linux Penguin will show up in the upper left corner
of the screen. Insert the ramdisk floppies when prompted.

partition program will be cfdisk. At this step we have to
add the PReP partition as mentioned above, a swap
partition and a root partition. Remember to write down
on a piece of paper what partition to use for the root
filesystem. Unless you have a really good memory, of
course.</P
></LI

Device Driver modules", "Configure PCMCIA Support", and
"Install Foreign Modules" can be skipped, as all necessary
driver are compiled into the boot floppy kernel.</P

network or cdrom. Both should work. (I have even installed
by floppy once, but this is something we really don't want
to do.)</P

Prelimenary, I've only done ftp install, but any installation
method should do, provided you have access to the media. I
have not been able to find an online version of the
installation instructions, but it should be quite
strightforward. If you have bought the boxed set, you have
probably got a printed manual on dead trees. A few things to
look up for anyhow:
<P

boot partition as described above. As a general rule,
use /dev/sda1 for this.

choose "Save" in the subscreens. "Add" and "Delete" won't
work. And besides, we already have done this, haven't we?
</P

unless you have a full CD set. The downloadable CD image
has only the base install packages.
</P
></LI

saying we are not one of those lucky bastards owning a Power
Macintosh computer. As this is something we should be
ashamed of. Ignore, sniff, and select "Ok". We'll fix
sound later.
</P
></LI
><LI
><P
> At the "PReP Bootloader Installation" screen, the
installer yells that it can't find a PReP partition. A
little strange, as we just made one. (We did, remember

prerequisites necessary. For a CD install, we need to replace
the installer program on the first CD before burning out the CD
ISO image. For a network install, we need a complete local ftp
or http mirror, made from the Mandrake Bamboo ppc ftp
directory, or the three CDs. Actually, we only need to replace
one single file, but because the installer is unable to
change package source during the installation (this is one
reason why Debian is a wonderful distribution), we need
local copies of all the files.

</P
><P
> Then we must change the first image by replacing the
installer inside it. This could be done on any operating
system able to mount a CD ISO image. The instructions below
are made for running on RedHat Linux. We presume the images are
all put in /var/tmp.
</P
><P
> First we mount the image by the loopback interface
<PRE
CLASS="SCREEN"
>mount -o loop=/dev/loop0 /var/tmp/MandrakeLinux-9.1-CD1.ppc.iso /mnt/cdrom</PRE
>
Then copy all files in the image to somewhere with plenty of
space, eg. /var/tmp, and unmount the image again:
<PRE
CLASS="SCREEN"
>mkdir /var/tmp/bamboo1
cp -va /mnt/cdrom/* /var/tmp/bamboo1
umount /mnt/cdrom</PRE
>
Now replace the installer image:
<PRE
CLASS="SCREEN"
>cd /var/tmp/bamboo1/Mandrake/base
rm mdkinst_stage2.bz2
wget http://users.linpro.no/ingvar/43p/images/Mandrake/mdkinst_stage2.bz2</PRE
>
Finally rebuild the installer image and, if you want, remove
the local copy of the cd contents:
<PRE
CLASS="SCREEN"
>cd /var/tmp
mkisofs -r -o MandrakeLinux-9.1-CD1.ppc.iso bamboo1/
rm -rf bamboo1</PRE
>
There. You now have a set of three working ISO images for
the 7248. Burn them out on CDs. Then insert the boot floppy
into the 7248 and turn the computer on. Disk-Jockey the
ramdisk floppy when prompted. Just do a normal CD
installation. See the installer notes below for details.

computer able to run a web or ftp server. Any Linux
distribution can do. A modern Windows or UNIX server should
also be able to do the job. The trick is to download all
necessary files, and change the installer file
Mandrake/base/mdkinst_stage2.bz with a patched one. Below
the the steps to get this done with the Apache web server on
a RedHat Linux installtion, and with the CD iso image files,
is described. (A complete download of the ppc archive from a
Mandrake ftp mirror should work allright too, but I prefer
to have the iso images availble.)

wget ftp://your.favourite.mirror/path/to/MandrakeLinux-9.1-CD3.ppc.iso</PRE

Mount the images via the loopback interface:
<PRE
CLASS="SCREEN"
>mkdir /mnt/bamboo1 /mnt/bamboo2 /mnt/bamboo3 /var/www/html/bamboo
mount -o loop=/dev/loop1 MandrakeLinux-9.1-CD1.ppc.iso /mnt/bamboo1

mount -o loop=/dev/loop3 MandrakeLinux-9.1-CD3.ppc.iso /mnt/bamboo3
cd -</PRE

Copy the base files, and symlink the package
directories, to a directory availble for the web server:
<PRE
CLASS="SCREEN"
>for i in base mdkinst share; do
cp -va /mnt/bamboo1/Mandrake/$i /var/www/html/bamboo/Mandrake; done
ln -s /mnt/bamboo1/Mandrake/RPMS1 /var/www/html/bamboo/Mandrake
ln -s /mnt/bamboo2/Mandrake/RPMS2 /var/www/html/bamboo/Mandrake
ln -s /mnt/bamboo3/Mandrake/RPMS3 /var/www/html/bamboo/Mandrake</PRE
>
Finally add my patched version of the installer image.
<PRE
CLASS="SCREEN"
>cd /var/www/html/bamboo/Mandrake/base
mv mdkinst_stage2.bz2 mdkinst_stage2.orig.bz2
wget http://users.linpro.no/ingvar/43p/images/Mandrake/mdkinst_stage2.bz2
cd -</PRE
>
You should now have a working local http mirror of the
Mandrake installation files. Now boot with the boot floppy,
and insert the ramdisk floppy when prompted. From the
installation menus, select network install, select http and
then give the address of the server where you just downloaded the
files. The http directory from the example above is "/bamboo"
