OK thanks for the help, really.
So the PXE boot is just something I have to live with. OK, it's not terrible, just seems like wasted bandwidth on an already strained 100M/bit switch. But I can live with it until someone comes up with a better solution.
Fdisk from the konsole is actually what I tried already. I got a message (forgot exact syntax) indicating that the system couldn't access the drive, even as SU. I was attempting this through KDE Desktop after the machine was fully booted, so maybe that was the problem? I was thinking of pulling the drive, booting from my Gpart cd and formatting the disk that way. Then wouldn't LMCE pick it up on reinstall into the core?
Apache and Webserver, awesome. That really is going to help. I did find instructions on how to install Dansgaurdian by searching the forums after my initial post so I'll give it a try later. The worst part about the kids (10 and 13) is that so many of my stupid neighbors have WAPs broadcasting without any security. They haven't figured it out yet, but all they have to do is drop the WIFI connection I've supplied them in favor of one of the many others. For this I have no defense except to try and talk to some of these people and teach them the way of WIFI security.
MythTV, did some more research and reading after first post, not even gonna try it for now. I will wait patiently for the next version of LMCE and hope the upgrade to Myth 0.21 is included.
I do have one new question. Assuming I get the second HD formatted and reinstalled into the core, how to I tell MythTV to use that space for recording TV? Right now it appears to be looking at one directory for storage space rather than several?
Thanks again for the help. If I was more of a Linux genius I would offer to try and help with some of this stuff but for now it's best to learn and do no harm.
