 BM> Can someone give me a list of opcodes for any instructions added for
 BM> the 586/Pentium chip?  (I've got a TASM qref that only shows up to 486
 BM> instructions.)
Get a program called AsmEdit, filename: AEDT184.ZIP.
From said program's (extensive) online help:
 Pentium + only instructions Ü
  ßßßßßßßßßßßßßßßßßßßßßßßßßßßßß
The following instructions are only implemented on 80586+:
 RDMSR
 WRMSR
 RDTSC
 CMPXCHG8B
 RSM
Note that these instructions can be changed on later processors like Intel's
Pentium Pro.
Opcodes:
  RDMSR                                 0Fh 32h
  WDMSR                                 0Fh 30h
  RDTSC  (undoc.)                       0Fh 31h
  CMPXCHG8B Mq                          0Fh C7h /r
  RSM  (undoc.)                         0Fh AAh
 Pentium Pro + only instructions Ü
 ßßßßßßßßßßßßßßßßßßßßßßßßßßßßßßßßß
The following instructions are only implemented on 80686+:
 CMOV
 FCMOV
 FCOMI
 RDPMC
All MMXÿInstructions will only be available on 80686, too.
