I've seen the same symptoms Sylvain described on the five Lite5200 boards that I have tried. Eepro100 network cards work fine, but the 3 brands of IDE cards I tried are not even visible in PCI config space. U-boot doesn't see them and Linux doesn't see them, booted either from dBUG or U-boot. Actually, one Lite5200/IDE combo comes close. Parts of the IDE cards PCI config info do read correctly sometimes. Different parts each time. I think this is likely a hardware issue with Lite5200 boards. -Dale Farnsworth ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
