confused on LVM (SOLVED)

i want to install Arch64 Duke. i just repartitioned my hard disk:

Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 1825 14659281 83 Linux
/dev/hda2 1826 2081 2056320 82 Linux swap / Solaris
/dev/hda3 2082 9729 61432560 5 Extended
/dev/hda5 2082 4514 19543041 83 Linux
/dev/hda6 4515 6947 19543041 83 Linux

as you can see, i have an extended partiton. is this what you people call LVM ? i don't know if i need to put "lvm" in HOOKS (or in "/etc/mkinitcpio") when building fallback image during Arch64 installation. ? "lvm" is not included in default HOOKS.

what else should i put in "/etc/mkinticpio" before 1st boot ? i checked this:

http://wiki.archlinux.org/index.php/Mkinitcpio

but it does not tell me whether i have lvm or not.

historically, the so-called MSDOS partition table format defined only four partitions at most, where boundaries are stored in a (4x) 16-byte table in the MBR.
soon, in order to overcome that limit, and to retain backwards compatibility, an extended partition scheme is introduced. it works by using one of the four slots and labelling it as 'extended', which means it is a 'placeholder', container partition that will encapsulate 'real' partitions and that 'real' partition boundary definition is defined like a linked list. now you understand why contained partitions (called 'logical' partitions) are always numbered >=5. the three remaining 'self-contained' partitions are being called 'primary'.

LVM is an entirely different scheme altogether, built to alleviate issues due to manipulating partitions (moving, resizing, etc...). basically, if you don't know what LVM is, you don't need it.
