3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ilia Mirkin <imirkin@xxxxxxxxxxxx> commit 5d2f4767c4eacab351b8450b0de4d3261fe1a957 upstream. The only BIOS on record that needs the 14 offset has a bios major version 2 but BMP version 1.01. Another bunch of BIOSes that need the 18 offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the bios major version, look at the BMP version. BIOSes with BMP version 0 do not contain a detectable script, so always return 0 for them.
