partition problem

[gaurav rajput]

hi,    well i am new to linux ,and having problem right at the very first step of partition.   HDD 10.2 Gb   with following partition :      hda1,hda5,hda6  -> Dos,extended Dos,extended Dos   when i go in for partition (by using suse-linux 6.4 CD) /,/swap,/tmp,/var,/usr : it takes at the   maximum hda2,hda3,hda4 only. on giving further partition it says no   primary partition available. while the only Primary partition ,that i saw using fdisk is Dos(hda1) only. while hda5,hda6 is extended Dos.
