Very easy... Add options PPS_SYNC to the file
/usr/src/sys/i386/conf/GENERIC.

Run

# cd /usr/src/sys/i386/conf
# config GENERIC
# cd ../.. (I believe but config tells you the correct path)
# make depend
# make
# make install

You know have a kernel with PPS support.

So I downloaded the latest slackware and installed it.

rolling out your on kernel is harder... as you say.

 RHEL is just plain annoying, Centos is about the best for me, but hey, I

CentOS is also the best for me but only for standard servers.

My NTP servers are embedded machines that run FreeBSD (NanoBSD).

Cheers,
Miguel

This is exactly why I prefer FreeBSD.

Isn't this an option for you?

Cheers,
Miguel

So none of my Serial I/O cards fit, being 5V. I have seen people take a
dremel to them to cut a 3.3V notch, but I am not a 100% sure this works.
