Esi

The source index register.

Edi

The destination index register.

Ebp

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

The general purpose segment register FS.

Gs

The general purpose segment register GS.

Eflags

The flags register.

Eip

The instruction pointer register.

Cr0

The control register 0.

Cr1

The control register 1.

Cr2
