Thanks Everyone for the Reply. Could it be that older K7S5A v.1 -v.3 has better AGP support?
Here is My Sequence:
1. I've plug the ATI 9600SE into K7S5A = NO POST. Computer Speaker beeps 3 times
2. Remove 9600se, and plug back in my Radeon 8500 = Post
....check ECS bios setting and (DISABLE+ ENABLE) AGP 4X
.....AGP 4X disable = No Post
.....AGP 4X enable = No Post
.....I've concluded the card was no good.
3. Put it in ABIT KR7A (old KT266A) viola, Post and go into Windows?
....
Conclusion - Radeon 9600SE is fine, but didn't work on my motherboard?
....Strange is that I had a
128mb Nvidia 5200, and that works fine on my K7S5A Pro
....Could it be that Radeon 9600SE is an
AGP 3.0 ONLY cards that won't work in AGP 2.0 MB?
K7S5A Manual say its an AGP 2.0 - 1.5V only MB

but I have read may forum post where people had successfully plugin an AGP 3.0 Card into AGP 2.0 MB
without problem
Does anyone out there has the same K7S5A PRO v5.0 with ATI 9600se?
