EXTENDED OP-CODE SET FOR 8088/8086
|
||
|
|
OR
|
||
|
|
WHAT INTEL FORGOT TO TELL
|
||
|
|
|
||
|
|
The following op-codes have been recently uncovered on the back of
|
||
|
|
several used bar napkins in Silicon Valley, CA. Several attempts have
|
||
|
|
been made to get confirmation of these heretofore unknown codes, but Intel
|
||
|
|
vehemently denies the existence of these in the 8088/8086 command set.
|
||
|
|
Several man-years have gone into the research of these codes. We would like
|
||
|
|
to thank the programmers responsible for discovering them. Unfortunately,
|
||
|
|
most of them are currently residents of the South Dakota Home for the
|
||
|
|
Mentally Unfit, and are unable to receive mail.
|
||
|
|
A final warning is in order. Since Intel denies the existence of these
|
||
|
|
codes, support of them cannot be guaranteed in subsequent hardware and/or
|
||
|
|
software releases. Please use with caution.
