I'm not sure whether this should go in the video or motherboard forum.
Here is the problem:
I purchased a used Tyan Trinity 400 (S1854, Rev. E, BIOS version 1.07) motherboard from a fellow AnandTech member. My original plans were to use this as a back-up motherboard for my main home system (Asus P3V4X w/ P3 600eb slot 1) since both motherboards use the same north and south bridges (VIA Apollo Pro 133A, north = 694X south = 596B). However, I recently replaced the P3 600eb slot 1 processor with a P3 933 slot 1 processor. So I decided to build a second system.
I had a few older video cards to use in this system (3dfx Voodoo3 3000 AGP, ATI Radeon 32 Mb SDR PCI, Cirrus Logic 5446 2 Mb PCI). I definitely don't want to use the Cirrus Logic card because it is 2D only. I prefer the Radeon over the Voodoo3 because I may put a DVD drive into the system and use it with my TV.
First, the Voodoo3 seemed to work fine. Also, the Cirrus Logic 5446 seemed to work fine. However, the Radeon PCI doesn't seem to work so well. Here are its symptoms:
1) When the computer is in the boot stage, the DOS screen where the system summary is shown (processor speed, hard drives, memory, etc.) is shifted such that each line starts midway across the screen and continues onto the next line. After it boots into Windows 98SE, the screen looks fine--it's just in some of the text screens (like in fdisk or something like that) where the display is messed up.
2) The framerates seem to be off. I had previously used this card in my main system. In my main system (P3V4X, P3 600eb), I got frame rates of about 70 fps and 58 fps in Quake 2 and Quake 3, respectively (640x480x32). With the Radeon PCI in the Tyan mobo, I get frame rates of 55 fps and 45 fps in Quake 2 and Quake 3, respectively (640x480x32). The frame rates are down about 20-25%.
I've tried this same card (Radeon PCI) in my kids' system (K6-2+ 450, Tyan s1590 motherboard) with no problems at all also.
Has anyone ever had any problems with the motherboard and a Radeon PCI? Any suggestions as to what may be the probem?
I did searches on several message boards and found a guy asking a question about an ATI 128 exhibiting the same shifted screen problem, but, unfornutately no one had replied to his question.
