I'm running whatever comes with stock FC3.  I followed Jarod's 
guide and have a fully functioning frontend when booting from 
the local drive.  Then I followed the guide at redhat for doing a 
netboot configuration.  When I changed the pc to do the netboot, 
and I got a kernel panic.  It goes by so fast, but it says something 
about the problem may be xfree86 trying to access something 
in the hardware layer directly.  The only way I can bring this 
into my home theater is if it is totally quiet.  Running from a hard 
disk is not quiet.  Although I'm also cheap, so I don't want to 
but any more hardware (like etherboot rom or usb interface + 
usb thumbdrive) to get this working.  Netboot should work.

It should be easy.  It is fairly easy on Solaris (I have lots of these

at work) and Red Hat was easy at one point...but doesn't work now.

No desire to rip or play disks.  Don't even have a CD or DVD drive 
in this frontend machine.  Just an old, relatively loud hard drive.

This is what I was thinking, but after googling around, deciding
it because of the possibility of the drive spinning up occasionally.

No usb interface on the case, but there is a usb header on the 
motherboard.  Already more than I want to do vs. doing pxelinux.

I'm with the (a) people.  No interest in buying a boot rom.  I have 
pxelinux working
