For BitLocker to make use of a TPM, it must be a 1.2 version and the system must have a BIOS that meets TCG requirements. While it is possible to use BitLocker without a TPM by storing the keying material on a USB flash drive, this is not the preferred customer configuration, nor is it expected to be typical usage due to the cost and manageability challenges associated with this mode of use.
