I'm looking at Inside Macintosh vol VI.
"When a multiscreen system starts up, one of the screens is determined to be the startup screen, the screen on which the "happy Macintosh" appears."
Is the Micron Xceed the "startup screen" when no external monitor is connected? Does anyone know or can point to a document explaining how the Xceed might disable internal video and advertise itself as the only video device? (Or does Xceed simply mirror what internal video is doing, but do it in grayscale? That would be one sneaky way of doing what they did.)
Is there any other video card that did this in a SE/30, making an external display off any kind the "startup screen" and only video device?
If you have a Micron Xceed I understand that it works just like an unequipped SE/30, but grayscale. Does the system think it has one video card or two? From what I read, if an external monitor is attached you lose the grayscale and the Xceed becomes similar to a Radius, providing a second screen on the external connector leaving the internal video as shipped. Is the total then two video devices or three?
I wish I had one to find out more about this.
