amd64 4GB dhcp

[oldsaw]

Perhaps unwisely, I upgraded my A8N-SLI Premium board from 2GB to 4GB of memory. Now my 64bit Linux systems seem unable to acquire IP numbers by DHCP through my cable modem, though they are recognizing all 4GB of the memory. The 32bit Linux systems, though they are only recognizing 3GB of the memory, are still working as before with DHCP. I haven't tried the Windows XP partition, but it is only a 32bit one anyway. Any ideas?

I resolved the problem - sort of. The Asus A8N-SLI motherboard carries two ethernet controllers: The Marvell 88E8001 NIC evidently won't work with any more than 3GB of RAM, but the nVidia CK804 NIC will work with 4GB of RAM. And yes, this is a reply to my own post which is sort of like talking to oneself, but it could be worse.
