"Discover" in what sense?  Do you mean that it doesn't show up in the
drop-down list in the combo box in the "Capture Options" dialog, or that
if you select it it fails to capture on it?

(The onboard controller is probably a PCI controller as well; it's just
not in a PCI expansion slot.)

Ethereal doesn't discover network interfaces, the OS does, on UNIX, and
the OS and WinPcap driver does, on Windows; Ethereal just reports what
interfaces it's told exists and can open for capturing.

UNIX, and the WinPcap driver, dsn't know the difference between onboard
and non-onboard interfaces there, or don't draw a distinction between
them there if they do; there's some other reason why the interface isn't
working.

If this is a UNIX system, try doing "ifconfig -a" (if your system
supports it) and see if the interface shows up; if so, try explicitly
telling Ethereal to capture on that interface.

If this a Windows system, download and install WinDump if you don't
already have it installed, and try doing "winpcap -D" from the command
line and see if the interface shows up.
