Intel Platform Information (Type 148)

Source: Intel Bay Trail reference code, Vlv2TbltDevicePkg, as EDK II published it up to edk2-stable201903: the OEM type 0x94 of SmBiosMiscDxe.

Gives the versions of the firmware components and some settings of an Intel Bay Trail platform, all of them as strings: the numbers the firmware writes in hexadecimal, and the settings as their values, e.g. 0 or 1. The data corpus holds it on Lenovo IdeaPad 100S, whose firmware is of Insyde.

The structure is told by its length of 26 bytes, since Intel server boards give type 148 to structures of other layouts, e.g. S2600WTT to one of 48 bytes, which gives the versions of the firmware components of the board.
