General
-------
Build a harddisk root image. The image will contain a partition
table defined by the following entries. Note that the resulting
partition table does not have CHS entries but only LBA entries, so
you need to switch your (x86-) Bios to LBA. Also note that fdisk will
complain about inconsistent CHS/LBA entries. You can ignore these warnings.
The ptxdist image will be put into the first partition.
Partition sizes
---------------
You can define a partition by giving the first and the last sector of
each partition. Sectors are units of 512 bytes. The first sector (sector 0)
is reserved for the MBR and the partition table.
Sectors can be given either decimal or in hex prefixed with 0x.
Beware that a 256MB flash card does not have exactly 256 * 1024 * 2 sectors
but slightly less.
Partition types
---------------
You can give the partition types as a decimal or hex (prefixed with 0x) value
See at the output of "sfdisk -T" for a list of valid types. No extended
partitions are supported at the moment.
grub
----
If you select grub in your config, it will be installed on the image and thus
give a bootable image for x86 PCs. The grub stage2 file will be installed right
after the MBR before the first partition, so you need to leave a hole before the
first partition. Starting the partition on sector 300 should be a safe value.
