All Pentiums are susceptible to the "F00F" bug, where a certain machine-language instruction (starting with the hex digits F0 0F) can lock the CPU up tight, requiring a physical reset. The workaround alters the system so that the instruction is trapped before any damage is done. In 2.2-STABLE and later (i.e. 3.* and 4.*), the wording has been changed to: "Intel Pentium detected, installing workaround for F00F bug" which, if nothing else, is at least grammatically correct :) -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
