	I am trying to use a Western Digital WD8003E Ethernet adapter
on a Compaq 386/20 machine, and am having very little success. Here's
some of the details:

	Computer: Compaq 386/20
		  Compaq VGA board
		  2 serial, 1 parallel port
		  2 meg memory using Compaq EMM
	WD8003e Ethernet Card:
		  IRQ selectable 2-7
		  I/O Address selectable h200-h3E0
		  RAM buffer selectable hA0000-hEFFFF

	I have installed several cards in other machines (286/386) and
have been able to get them running with little problem. WD dox explain
all the settings and their possible conflicts with system components, so
here's my questions:
	+ has anyone used this card in this particular machine, or 
	similar ethernet cards?
	+ there two switches on the VGA card marked VRAM and BIOS that
	have both 8 and 16 settings... What do they do? WD C-support
	suggested running the VGA card in 8 bit mode but I can't find
	any detailed explaination in the Compaq dox.
	+ other 386 machines here would not use the Ethernet card unless
	"shadow-RAM" was disabled... Does the 386/20 have this feature,
	and if so how is it disabled?

	Other salient points:
	The diagnostic program runs okay for the card at various RAM
buffer areas thruout the range, and the interrupt test works A-OK when
using IRQ5. All TSR stuff has been disabled to test the E-card, so I 
don't think that is a problem. I can get the card working fine in the
diag. test, but it still won't communicate with a "live" ethernet (yes
that was tested as well...)
	Any help would be greatly appreciated, E-mail or post yer 
choice....
