dos disklabel number of partitions

hi All,
I have seen on SUSE we are able to create 63 disk partitions with dos disk lable. what i know is its 15 (3 Primary and 11 Logical with extended partition). Any one has SUSE documentation which can help if its 15 only.
If you need more than four partitions, create an extended partition as the fourth partition (or earlier). This extended partition should occupy the entire remaining free cylinder range. Then create multiple logical partitions within the extended partition. The maximum number of logical partitions is 63, independent of the disk type. It does not matter which types of partitions are used for Linux. Primary and logical partitions both function normally

You should enable UEFI Secure Boot. Have a look at:
