9 Do you remember the x87 bugs discovered in the original i586 Pentiums?
10 Never fixed.
11 Still built into every Intel CPU.
12 Intel does NOT replace "defective-by-design" hardware.
13 Instead, every OS is required to "software emulate" the FPU.
14
15 Search for "errata-not-bug".
16 Intel's term for their screw-ups in their CPUs.
17
18 Intel is only releasing patch code for the last five years of products.
19
20 And ... if you read up on the "e-mails" being posted ...
21 ... It looks as if Intel is NOT going to fix this in future CPUs either.
22 Instead, every OS will be required to "work-around-this".
23
24 Perhaps the reason "someone" tried to implicate this effects ALL CPU
25 architectures?
26 ( IBM RISC 6000, PowerPC, DEC Alpha, IBM System/390, Sun SPARC64, for
27 example )
28
29 Intel did try to make their "patch" mandatory for AMD CPUs ( with NO
30 disable switch ).
31 Why?
32 Think about it.
