AMD 64 HW not working

[Rob]

I did get a valuable hint. The memory banks have to have  equal amounts 
of memory.  I did this. Now in addition to the red power light, I get an 
LED indicator saying 4.  Still no video of any sort. I currently have an 
old Radeon card  installed.  I put in an old card thinking that it would 
be more likely to be recognized.  But not even  SVGA.   Is there a 
better choice for card?  Something I can purchase off the shelf ?    Thanks,

Rob.
