If > I had a cyrix CPU, I would do it. hmm, just curious, why does this need to be in the kernel? at least for the 6x86 ( which is what i'm running ), most (if not all?) of the cyrix optimization can be done in user space since you are just tweaking the configuration registers. it is pretty easy to write a userland program that sets the registers to the desired value (open /dev/io , {read,write}_cyrix_reg ). i have a 6x86MX 200 that is working fine with such a setup. balger@ecst.csuchico.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
