Thx for the hint , Rick.  
BIOS looks quite fresh  - (the box comes quite new direct from FSC.
Phoenix Trusted Core Server 
Version:  1-05-1818
Build Time: 12/20/2005  11:07:30



Would it be a good idea to install 32-bit kernel first.  And when the
machine is up,  to add 64-bit kernel ?



When booting with RHEL 4 AS   Install-DVD   for 64 bit  AMD64  and Intel
EM64T   
I see:
....  Running sbin loader
Loading sata_nv driver
Kernel panic - not syncing:   PCI-DMA: high address but no IOMU.
( for information:  system has 8 GB memory) 



When running  with  FC4 32-bit   /proc/cpuinfo looks quite well
