Intel 486SX


essor> An ef="module.php?name=Lexikon&file=search&eid=1&query=Intel 486DX">Intel 486DX ef="module.php?name=Lexikon&file=search&eid=1&query=microprocessor">microprocessor with its ef="module.php?name=Lexikon&file=search&eid=1&query=floating-point unit">floating-point unit disconnected. All 486SX chips were fabricated with FPUs. If testing showed that the CPU was OK but the FPU was defective, the FPU' s power and bus connections were destroyed with a laser and the chip was sold cheaper as an SX, if the FPU worked it was sold as a DX. [Was this true of all 486SX chips?] Some systems, e.g. Aopen 486SX, allowed a DX to be plugged into an expansion socket. A board jumper would disable the SX which was hard to remove because it was surface mounted. Some SX chips only had a 16-bit wide external ef="module.php?name=Lexikon&file=search&eid=1&query=data bus">data bus. The DX has a pin to select the data bus width (16 or 32). On the smaller SX, that line is ef="module.php?name=Lexikon&file=search&eid=1&query=hard-wired">hard-wired to 16 inside the package. This is similar to the 286 SX, which was a 16-bit processor with an 8-bit external data bus. The ef="module.php?name=Lexikon&file=search&eid=1&query=Jargon File">Jargon File claimed that the SX was deliberately disabled ef="module.php?name=Lexikon&file=search&eid=1&query=crippleware">crippleware. The German computer magazine, "c' t", made this same theory the basis of an ef="module.php?name=Lexikon&file=search&eid=1&query=April Fools Joke">April Fools Joke. They claimed that if one drilled a hole of a specified diameter through the right point on a SX chip, this would brake the circuit that disables the FPU. Some people actually tried (and then bought themselves new processors). (1997-02-14)
