I presume your distribution has some sort of command-line "fdisk"
program that can print out the partition table. Under NetBSD, it would
work like this:

    stoic $ sudo fdisk sd0
    Disk: /dev/rsd0d
    NetBSD disklabel disk geometry:
    cylinders: 500, heads: 8, sectors/track: 32 (256 sectors/cylinder)
    total sectors: 1024000

    BIOS disk geometry:
    cylinders: 1024, heads: 8, sectors/track: 32 (256 sectors/cylinder)
    total sectors: 1024000

    Partition table:
    0: Primary 'big' DOS, 16-bit FAT (> 32MB) (sysid 6)
	bootmenu: USB DOS
	start 32, size 65504 (32 MB, Cyls 0-255), Active
    1: NetBSD (sysid 169)
	bootmenu: NetBSD
	start 65536, size 958464 (468 MB, Cyls 256-3999)
    2: <UNUSED>
    3: <UNUSED>
    Bootselector enabled, timeout 10 seconds.

That information, along with from perusal of

    http://en.wikipedia.org/wiki/Partition_table

may help.
