Sort of, I have used Linux in the past (including building Kernels) but
only came back to it recently I've also played with Solaris on a Sun
Ultra. I'm looking to replace some of my servers etc which are running
W2K server. I have tried Fedora but it is not stable enough for a
production environment. Hence Free BSD. BTW neither FC2 or 3 will
install on the Proliant - probably due to lack of EISA support.

Its running now, but taking it's time. I'm not surprised as it only
running on 1 cylinder so to speak.

Again many thanks.
