To provide a demonstration for identifying the BIOS version, I crashed my system this morning and then used the resulting dump to experiment with various debugger commands to attempt to determine the BIOS version, release date, and system make/model. I stumbled upon the !sysinfo extension debugger command and looked at the accompanying documentation. From a crash dump perspective, you can get useful information in a long form and a short form, both are demonstrated below. The !sysinfo machineid command displays BIOS information and motherboard information fairly compactly, while the !sysinfo smbios command dumps the full content of the SMBIOS table and displays other useful information about the processors, physical memory, and a couple of other onboard devices.
Another neat trick is that this information can be gained from a live system without needing to reboot into debugging mode using LiveKD.
The short version:
0: kd> !sysinfo machineid
