If maintech changes a motherboard, the mac address changes and BIOS settings are lost. So, we need to:
...
- Update mac address in
...
- /etc/sysconfig/network-scripts/ifcfg-eth1
...
- . To this boot to single-user mode (hit power button, then hit "e" at grub boot menu, and attach "s" to end of grub boot line)
...
- need to REPROGRAM BIOS SETTINGS as desribed here.
