I guess then, upgrading FreeBSD from source would require building and installing on a new partition, in this case a new, bigger, hard drive. There would be the logistic matter of how and where to switch from MBR to GPT. I don't recognize the acronym KSE, didn't know about that particular ABI break in 5.4. Back then, with FreeBSD <= 5.x, or maybe it was <= 4.x, the boot floppy always hung probing for devices, was never able to boot. I believe my first installation of FreeBSD was 7.x, probably 7.0. I could run Linux (Slackware), but FreeBSD could only run in safe mode, possibly because of a bug in the hard drive hardware. That hard drive subsequently went all the way bad. Tom
