-: Also, if detecting x87 could be dangerous (i.e. risk crashing the
-: program), I would vote against it.
On a related note, I have seen lots of ways to *detect* an FPU
(a 387 to be exact), but what about *testing* the FPU for functionality?
I remember installing lots of 387's; it was easy enough to install the
chip and then adjust a DIP switch, add/remove a jumper, then run some
utility (e.g., Norton's SI) just to make sure it was detected, but
afterwards you never really knew if the chip was really working as it
should. If a program would run with or without a 387, would a faulty
387 ever have been detected after installation? This still bothers me.
Does anyone know of a test suite for testing FPU functionality?
