A point to remember -- you get what you pay for.  My experiences with
RTL 8139 NICs have not been happy ones.  Although a system with a single
RTL 8139 NIC will generally "work", my own personal performance
measurements have shown this card to be a truly abysmal performer,
especially under (simulated) heavy load.  Whenever I've tried a system
with two RTL 8139's in it in the past that system has just crashed.  At
this point even though no-name RTL 8139 NICs can easily be bought for
$10 at many computer stores, I would never use one.

I'd find some OTHER inexpensive motherboard that has a decent NIC
onboard, even if you have to pay more for it.  Or just add a NIC to your
configuration.

If remote PXE boot/install is your goal, intel and 3com have cards that
support pxe booting.  A number of vendors have motherboards with e.g.
onboard eepro100 NICs with PXE support.
