Been working on a nightmare of a disaster rfm that started with no computer. I managed to pick up a used computer along with 2 rom/prism sandwiches. After replacing fan and ps, I have managed to get computer to boot to bios ( with prism card removed) on the bench hooked up to a vga monitor. When I reboot with either prism card I get nada - no signal ( yes I do have a cga-via converter). I find it hard - not impossible - to believe I have 2 bad prism boards. Since I have not had a chance to see a working one in operation I am curious if I am missing something obvious? I have this outside game with no driver board or anything else connected - will this effect PCI boot?

Any suggestions appreciated

Hmmm. Do you need an EGA (not VGA) monitor to display the video from the PRISM card? Anyone remember?

Here is a thread just to make sure you have the wires for conversation properly pinned out, assuming you have a LCD in there and not the CRT being you have the converter.

Thanks for the feedback. I am starting to think that the problem is on the display side rather than the cpu or the prism. I will try to see if I have an cga arcade monitor around or will look at the conver

Sorry - accidental send.....

Converter as I have a second one around.

One other question - does anyone have the slightest idea what the hell the led on the prism card indicates? I have one that is solid on and another card that starts solid then goes out and starts blinking rapidly. I have searched everywhere and can find nothing on what that light indicates.

I don't know what the LED is supposed to indicate, but on my (fully working) machine the LED behaves like your second one. So your first prism card may have some issues.

The one with the solid LED is not booting. The one that goes into rapid blinking may be booting, I'd have to see the LED. Can you post a video?

Nothing else needs to be connected for the computer to boot. If you boot into BIOS, you should boot with the PRISM if it's good.

Thanks for the information. Knowing the second card was booting was a huge help as it let me focus on that board. Problem was with the monitor. Once I connected another one I had and got settings correct it showed that it was booting just fine. Appreciate the help - as well as the converter which I picked up from you a couple weeks back.

I've attached some info that may help.
