Interware VDR-2A: can it sense connected display?

I recently bought one of these from a member here, and it works great. I thing I remember from back in the day that some video cards could sense when a monitor was connected. Anyone know if this one can somehow?

If I boot the machine with nothing connected, and the menu bar is on the external display, I see nothing on the internal display. I'd like to be able to use the machine without the external display connected. Do I need to remember to move the menu bar, or is there some way to automate this?
 
from what I understand, the earlier interwares don't have the ability to "sense" an attached display.

as long as you have working PRAM, the menu bar/boot screen should be remembered after you set it.
 
Thanks. Yes, it does remember. I just have to remember to move it before I take the machine somewhere without a display available.
 
Holding ”0” on your keyboard while booting should disable the card and give you internal screen only. 1-5 is different screen options.

Thank you! Exactly what I was looking for. Is this from a manual that is available somewhere?
 
I finally got a chance to try to startup keys, and they don’t work with my card. I thought maybe it was because I have it stacked on top of a Diimo, but I put it in alone and still no luck. Maybe it’s the firmware version or my ROM. Oh well, it’s not important.
 
Hmm that’s odd. I have that exact card and it works fine for me. Make sure to press and continue to hold the number before you flip the power switch, and dont release until the welcome to macintosh screen shows. What rom version is on your card?
