It actually uses the <command>parted</command> to +do the on-disk partitioning. + +</para> + + <note> + <title>EFI Recognized Formats</title> +<para> + +The IA64 EFI firmware supports two partition table (or disk label) +formats, GPT and MS-DOS. MS-DOS, the format typically used on i386 +PCs, is no longer recommended for IA64 systems. Although +the installer also provides the <command>cfdisk</command>, +you should only use the <ulink url="parted.txt"> +<command>parted</command></ulink> because only it can manage both GPT +and MS-DOS tables correctly. + +</para></note> + +<para> + +The automatic partitioning recipes for <command>partman</command> +allocate an EFI partition as the first partition on the disk. +You can also set up the partition under the <guimenuitem>Guided +partitioning</guimenuitem> from the main menu in a manner similar to +setting up a <emphasis>swap</emphasis> partition. + +</para><para> + +The <command>partman</command> partitioner will handle most disk +layouts. +For those rare cases where it is necessary to manually set up a disk, +you can use the shell as described above and run the +<command>parted</command> utility directly using its command line interface. +Assuming that you want to erase your whole disk and create a GPT table +and some partitions, then something similar to the following command +sequence could be used: + +<informalexample><screen> + mklabel gpt + mkpartfs primary fat 0 50 + mkpartfs primary linux-swap 51 1000 + mkpartfs primary ext2 1001 3000 + set 1 boot on + print + quit +</screen></informalexample> + +This creates a new partition table, and three partitions to be used as +an EFI boot partition, swap space, and a root file system. Finally it +sets the boot flag on the EFI partition. Partitions are specified in +Megabytes, with start and end offsets from the beginning of the disk. +So, for example, above we created a 1999MB ext2 file system starting +at offset 1001MB from the start of the disk. Note that formatting swap +space with <command>parted</command> can take a few minutes to +complete, as it scans the partition for bad blocks. + +</para> + </sect2> + + <sect2 arch="ia64"><title>Boot Loader Partition Requirements</title> + +<para> + +ELILO, the ia64 boot loader, requires a partition containing a FAT +file system with the <userinput>boot</userinput> flag set. +The partition must be big enough to hold the boot loader and any +kernels or RAMdisks you may wish to boot. A minimum size would be +about 20MB, but if you expect to run with multiple kernels, then +128MB might be a better size. + +</para><para> + +The EFI Boot Manager and the EFI Shell fully support the GPT table +so the boot partition does not necessarily have to be the first +partition or even on the same disk. +This is convenient if you should forget to allocate the partition and +only find out after you have formatted the other partitions on your disk(s). +The <command>partman</command> partitioner checks for an EFI partition +at the same time it checks for a properly set up <emphasis>root</emphasis> +partition. +This gives you an opportunity to correct the disk layout before the +package install begins. +The easiest way to correct this omission is to shrink the last partition +of the disk to make enough free space for adding an EFI partition. + +</para><para> + +It is strongly recommended that you allocate the EFI boot partition +on the same disk as the <emphasis>root</emphasis> filesystem. + +</para> + + </sect2> + + <sect2 arch="ia64"><title>EFI Diagnostic Partitions</title> + +<para> + +The EFI firmware is significantly more sophisticated than the usual +BIOS seen on most x86 PCs. +Some system vendors take advantage of the ability of the EFI to +access files and run programs from a hard disk filesystem to store diagnostics +and EFI based system management utilities on the hard disk. +This is a separate FAT format filesystem on the system disk. +Consult the system documentation and accessories that come with the +system for details. +The easiest time to set up a diagnostics partition is at the same time you +set up the EFI boot partition. + +</para> + + </sect2> |
