It certainly isn't how I'd set it up.  I'm pretty sure the boot
partition is the 102MB "MBR Entry 2" partition.

They're nuts.  The FAT-32 is where Windows is.  The "MBR Entry 3" or
"Extended" partition is where the other stuff is.  It contains the two
"Unnamed" partitions, one of which is "/" and the other is the swap
partition.

I'll comment each partition below with what I think it is.

Dell-specific utilities (disk recovery, etc.).  Linux /dev/sdb1, grub
(hd1,0)

Windows.  Linux /dev/sdb2, grub (hd1,1)

/boot for Linux.  Linux /dev/sdb3, grub (hd1,2)

Extended partition containing virtual drives.  Linux /dev/sdb4, grub
(hd1,3)

> >>>UnNamed________ Volume_____ 30043mb_____   Linux native

"/" for Linux.  Linux /dev/sdb5, grub (hd1,4)

Swap space.  Linux /dev/sdb6, grub (hd1,5)

Note that in Linux, the extended partition is virtually ALWAYS partition
4, and any partition over 4 (5-16) will be in that extended partition.
