![](images/i.jpg) *Note that 1 and 4-byte displacements, but not 2-byte displacements, are supported for 32-bit addressing. Code size can be greatly improved by keeping stack frame variables within 128 bytes of EBP, and variables in pointed-to structures within 127 bytes of the start of the structure, so that displacements can be 1 rather than 4 bytes.*

However, because 32-bit addressing supports many more addressing
combinations than 16-bit addressing, the Mod-R/M byte can't describe all
