Only boots when monitor is connected (don't want that!)

Posted on 2004-10-19

Hi, all.

I want to control "box A" and "box B" from my laptop via VNC. I have no keyboard or monitor plugged into box A or box B -- only power and ethernet.

This works just fine on box B, but box A only boots if a monitor is plugged into it. I looked through the bios settings, and found nothing helpful.

Box A:
Asus A7M266 mobo / Award Medallion BIOS v 6.0 / 1.33 GHz Athlon C / nVidia GeForce 2 in AGP slot.

Any ideas??

Some PCs simply won't boot unless there is a keyboard attached to the system.  If it doesn't find one during it's POST, it will either beep continuously, or just sit there.  It's not an elegant solution, but try attaching a keyboard to A and see if it will boot then.

Well, actually I solved the keyboard part of my problem and never mentioned it here.  In the bios, there is a setting to ignore keyboard error.  So as it is now, if a monitor is connected and NO keyboard is connected, it boots up just fine.  But if there is no monitor connected it won't boot.  Not even a beep, or post, or anything.  Just silence (except for fans) and a black screen (if I plug in a monitor afterwards to see what's happening).

Remove agp card.
If you dont need vga it doesnt matter.  

Then change bios setting to onboard, or whatever.  Play a while with that.

Wouldn't I have to set the bios, THEN remove the agp card ??  ;-)  (there's no onboard viseo in this MB.)

Will give that a try.  Thanks.

oh! i didnt know that...

well then again, switch the card, get a cheap one, nvidia always gives that kind of trouble when no monitor is connected.

Someone out there suggested attaching a Mac --> VGA adapter (or shorting pins 4 & 11 on the vga port).  Will try this and report back.

Thanks to all.

Well, none of the above seemed to work, so I just connected the computer to my KVM, with no monitor on the other end.  I wanted to avoid having to do it this way, but it boots.  It's a bandaid fix, but I guess it will do until I can figure this out.

Thanks for all replies.
