PC partitioning properties

• A partition table has a maximum of 4 entries

• • • MBR can hold 4 PRI, or 3 PRI and 1 extended
    • EBR usually holds 1 logical, and 1 'next' extended partition, forming an infinite linked list of logicals

• Partitions can be 'hidden' using a type value

• • • One primary or multiple visible ones allowed by OS
    • Hiding logicals is usually not supported
    • Real visibility also depends on other OS specific settings, and availability of the right FS drivers

• BIOS boots primaries only (on some disks)

• • • Bootmanagers might allow boot from logical (OS2)
