Well,
John McCluskey and Kamal were right -- the reg code I had was for Foundation with ISIM. A new code for Foundation without ISIM works under Linux!
Xilinx: This might be something to add to an FAQ on Foundation ISE Linux installation.
Just wondering, is it normal for the installer to finish and not add any icons or anything?
I found the ISE binary in one of the folders and executed it and the GUI came up and worked.
Next step is the EDK...
Thank you all! Ram.
