On Tue, 7 Sep 1999, Sean 'Captain Napalm' Conner wrote about using
self-modifying code to check the size of the prefetch buffer to
differentiate between 8086 and 8088.
But does anyone have a good way to differentiate between 386SX and 386DX?
Possibilities that come to mind include brute force speed comparison?
Compare speed of moving data that is word v doubleword aligned?
SX has 24 bit address bus, DX has 32 bits. Any easy way to test?
