Windows installs its own version of HIMEM.SYS [15] on DOS 3.3 and higher. Windows HIMEM.SYS launches 32-bit protected mode XMS (n).0 services provider for the Windows Virtual Machine Manager, which then provides XMS (n-1).0 services to DOS boxes and the 16-bit Windows machine (e.g. DOS 7 HIMEM.SYS is XMS 3.0 but running 'MEM' command in a ...
W: If set, the operation is performed on 64-bit operands. R: Extends the REG field to 4 bits. X: Extends the INDEX field of the SIB byte (if present) to 4 bits. B: Extends the R/M field (or the SIB byte's BASE if MOD≠11 R/M=100) to 4 bits. There is one additional effect of a REX prefix: a REX prefix changes how byte registers are addressed.
