Take a look at win32 api function GetSystemFirmwareTable.

edit:

Above is valid for reading SMBIOS data. To read actual BIOS memory, code need to be run in kernel mode.

There is a Win32_BIOS WMI (Windows Management Instrumentation) class that you will be able to instantiate and query through methods in the System.Management namespace. I don't know specifically if this class has a property for BIOS chipset - if not, you could maybe look at Win32_Processor although this is designed to return information on the CPU, not the BIOS.
