Surely you meant x87 FP instructions? The 486 didn't have SSE instructions.

- craz8 7y agoProbably not 486 - this was 1999-2000 timeframe, so some sort of Pentium thing. It was definitely the new instructions though, so whatever Intel chip had the new features had this 1 stepping that had this bug (and it wasn’t the first version of the chip either)
- gpderetta 7y agoMMX then instead of SSE?
- wahern 7y ago486 didn't necessarily have FP, either. I started using Linux on a 486SX. FP instructions were trapped and emulated by the kernel.
