The base pointer register.

Esp

The stack pointer register.

Cs

The code segment register.

Ds

The data segment register.

Ss

The stack segment register.

Es

The extra segment register.

Fs

Remarks

If the RegisterContextType member of a WHEA_XPF_CONTEXT_INFO structure is set to XPF_CONTEXT_INFO_32BITCONTEXT, the RegisterData member of that structure contains a WHEA_X86_REGISTER_STATE structure.
