PMFJI, but re: pentium bug:
I've rendered about 10,000 frames on a P5 in the last six months or so, and
have not seen any evidence that Imagine is affected by the FDIV bug in the
Pentium chip. I frequent the Dell user group, and am amazed at the way people
are freaking out about this problem. Somebody came up with two seven digit
numbers that, when divided and successively multiplied, came up with a wrong
answer; the whole forum seemed to blow a collective gasket. I did some tests
myself to try and find a number combination that would fail, and after a day or
so of searching (and you can search a LOT of numbers on a P5-90) I gave up. I
think Intel's "once in 27,000 years" comment is a bit irresponsible, but IMHO
the Pentium FDIV bug shouldn't affect Imagine in any significant (or
detectable) way, if at all.
