I've bought this card, by FCC ID lookup it's a Joytech GD26ACVL2M.
It has a single jumper switch in the corner, in the immediate vicinity of VESA connector's pins.
Judging by traces around that jumper it selects some signal to come either directly, or inverted (the MC74F04N chip nearby is inverter).
I've never had any VESA cards before, so I've no idea what was possible to select with jumpers on VLB video cards.
Any ideas what it could be?
