Hello,
?
I have picked up an oscilloscope 54810
I have some problems on it, but it’s settled.
Meanwhile, I tried to put the graphics card 54810-66505 on another motherboard (which also had its video output built in), for tests.
Since the video card no longer provides output. The screen is black.
If I put an old video card trident, the screen works.
I think my manipulation must have "written" information in the chip 65550. (Some register?)
What manipulation could reactivate it??
NB: the card is visible in the bios pnp/pci parameters
Your opinion.?
cdt
