This is version 0.0.05 of the (GPLv2 licensed) Linux driver required to carry out firmware upgrades on Insyde Softwares UEFI platform, using the H2OFFT-Lx(64) utility on GNU Linux. The utility itself is not available here, since it does not seem to be GPL licensed.
Upon loading the module, if you run into the `-1 Invalid module format` error message, this suggests you are using a module that was built on a different platform (ia32 vs. x64) or for an ABI incompatible kernel version.
