Media status 8808 indicates auiDisable, linkDetect and enableSQE. The
first item is obviously wrong, as we try to use the AUI port. The second
is OK (as linkBeatEnable is cleared) and the third is desired for AUI
operation.
Media status should read 0808 in this case, as the auiDisable bit should
not be set. The lines which impose these media settings are around middle
of vortex_open():

	if (dev->if_port != XCVR_NWAY) {
		EL3WINDOW(4);
		outw((inw(ioaddr + Wn4_Media) & ~(Media_10TP|Media_SQE)) |
			 media_tbl[dev->if_port].media_bits, ioaddr + Wn4_Media);
	}

Please try to change these into:

	if (dev->if_port != XCVR_NWAY) {
		EL3WINDOW(4);
		outw((inw(ioaddr + Wn4_Media) & ~(Media_10TP|Media_SQE|0x8000)) |
			 media_tbl[dev->if_port].media_bits, ioaddr + Wn4_Media);
	}

and tell us if it works (and provide the same "options=1 debug=2" output 
plus vortex-diag -a). I'll then make a better patch (which will define
another Media_ constant to be associated with AUI operation).

Sincerely,
