It actually uses the parted to +do the on-disk partitioning. + + + + + EFI Recognized Formats + + +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 cfdisk, +you should only use the +parted because only it can manage both GPT +and MS-DOS tables correctly. + + + + + +The automatic partitioning recipes for partman +allocate an EFI partition as the first partition on the disk. +You can also set up the partition under the Guided +partitioning from the main menu in a manner similar to +setting up a swap partition. + + + +The partman 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 +parted 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: + + + mklabel gpt + mkpartfs primary fat 0 50 + mkpartfs primary linux-swap 51 1000 + mkpartfs primary ext2 1001 3000 + set 1 boot on + print + quit + + +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 parted can take a few minutes to +complete, as it scans the partition for bad blocks. + + + + + Boot Loader Partition Requirements + + + +ELILO, the ia64 boot loader, requires a partition containing a FAT +file system with the boot 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. + + + +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 partman partitioner checks for an EFI partition +at the same time it checks for a properly set up root +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. + + + +It is strongly recommended that you allocate the EFI boot partition +on the same disk as the root filesystem. + + + + + + EFI Diagnostic Partitions + + + +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. + + + + -- cgit v1.2.3
