I use Optiplex GX1's.  These have the built-in 3c905, and they do
PXE-boot quite nicely.  Matter of fact, I think Jim McQuillan and
someone else were selling reconditioned Optiplex GX1's as LTSP thin
clients.  The catch is that they do need to have a recent BIOS in them,
because some of the earlier BIOSes for these boxes did have buggy
PXE-boot code in them.  I found that out the hard way during a K12LTSP demo.

How'd you install Etherboot to the HD?  The way I do it is by doing "cat
MyEtherbootImage > /dev/hda".  Note that I didn't specify a partition,
but rather the HD itself.

Also, it's possible that the Optiplex is configured to PXE-boot, and
further, that it has one of the early buggy BIOSes in it.  Best to turn
that off.  IIRC, it's called "Network boot".
