So I got a very nice Tyan Thunder K7 (s2462) as the center piece of an Athlon MP retro build I‘m currently working on. Since it is the very first Athlon MP board I was hoping that some of you have it and have some experience with GPU compatibility. I thought this was going to be easy. But to my surprise it posts neither with a Radeon 9800 Pro nor a Geforce4. Both of which I tested successfully in a Super 7 board (GA-5AX). Earlier cards like a TNT work just fine. (All AGP.) As far as I can see AGP settings options (jumpers, BIOS) are very limited.
I am using a 620 Watts PSU by Seasonic and have the required adapter cable. I therefore do not think it‘s a wattage issue.
The symptoms are that the screen stays black and I can tell by the keyboard LEDs that the Tyan is stuck in a loop. Keyboard LEDs do the „power on“ flash, stay off for about 20 seconds, ... rewind, repeat.
Are those AGP cards too „modern“ for the AMD 760MPX? Should I try a Geforce3 or earlier Radeon? Any recommendations? Or might there be something wrong with the board?
