What is the penalty for including either of these lines in my kernel if it is not needed? quote from the handbook: ================================================ options MATH_EMULATE This line allows the kernel to simulate a math co-processor if your computer does not have one (386 or 486SX). If you have a Pentium, a 486DX, or a 386 or 486SX with a separate 387 or 487 chip, you can comment this line out. Note: The normal math co-processor emulation routines that come with FreeBSD are not very accurate. If you do not have a math co-processor, and you need the best accuracy, I recommend that you change this option to GPL_MATH_EMULATE to use the superior GNU math support, which is not included by default for licensing reasons. ================================================ thanks To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
