The <command>partman</command> disk partitioner is the default
15
partitioning tool for the installer.
16
It manages the set of partitions and their mount points to ensure
17
that the disks and filesystems is properly configured for a successful
18
installation. It actually uses the <command>parted</command> to
19
do the on-disk partitioning.

The IA64 EFI firmware supports two partition table (or disk label)
39
formats, GPT and MS-DOS. MS-DOS, the format typically used on i386
40
PCs, is no longer recommended for IA64 systems. Although
41
the installer also provides the <command>cfdisk</command>,
42
you should only use the <ulink url="parted.txt">
43
<command>parted</command></ulink> because only it can manage both GPT
44
and MS-DOS tables correctly.

The automatic partitioning recipes for <command>partman</command>
60
allocate an EFI partition as the first partition on the disk.
61
You can also set up the partition under the <guimenuitem>Guided
62
partitioning</guimenuitem> from the main menu in a manner similar to
63
setting up a <emphasis>swap</emphasis> partition.

74
The <command>partman</command> partitioner will handle most disk
76
For those rare cases where it is necessary to manually set up a disk,
77
you can use the shell as described above and run the
78
<command>parted</command> utility directly using its command line interface.
79
Assuming that you want to erase your whole disk and create a GPT table
80
and some partitions, then something similar to the following command
81
sequence could be used:
83
<command>partman</command> �ѡ��ƥ�����ʡ��ϤۤȤ�ɤΥǥ������쥤������

mkpartfs primary linux-swap 51 1000
96
mkpartfs primary ext2 1001 3000
100
</screen></informalexample>
103
This creates a new partition table, and three partitions to be used as
104
an EFI boot partition, swap space, and a root file system. Finally it
105
sets the boot flag on the EFI partition. Partitions are specified in
106
Megabytes, with start and end offsets from the beginning of the disk.
107
So, for example, above we created a 1999MB ext2 file system starting
108
at offset 1001MB from the start of the disk. Note that formatting swap
109
space with <command>parted</command> can take a few minutes to
110
complete, as it scans the partition for bad blocks.

136
ELILO, the ia64 boot loader, requires a partition containing a FAT
137
file system with the <userinput>boot</userinput> flag set.
138
The partition must be big enough to hold the boot loader and any
139
kernels or RAMdisks you may wish to boot. A minimum size would be
140
about 20MB, but if you expect to run with multiple kernels, then
141
128MB might be a better size.

The EFI Boot Manager and the EFI Shell fully support the GPT table
154
so the boot partition does not necessarily have to be the first
155
partition or even on the same disk.
156
This is convenient if you should forget to allocate the partition and
157
only find out after you have formatted the other partitions on your disk(s).
158
The <command>partman</command> partitioner checks for an EFI partition
159
at the same time it checks for a properly set up <emphasis>root</emphasis>
161
This gives you an opportunity to correct the disk layout before the
162
package install begins.
163
The easiest way to correct this omission is to shrink the last partition
164
of the disk to make enough free space for adding an EFI partition.

It is strongly recommended that you allocate the EFI boot partition
183
on the same disk as the <emphasis>root</emphasis> filesystem.

The EFI firmware is significantly more sophisticated than the usual
201
BIOS seen on most x86 PCs.
202
Some system vendors take advantage of the ability of the EFI to
203
access files and run programs from a hard disk filesystem to store diagnostics
204
and EFI based system management utilities on the hard disk.
205
This is a separate FAT format filesystem on the system disk.
206
Consult the system documentation and accessories that come with the
208
The easiest time to set up a diagnostics partition is at the same time you
209
set up the EFI boot partition.
