5 Recover device from corrupt NVAM

When vendor id and/or device id have been modified and B57diag can longer find the device, the
following steps can be followed to recover the missing device.
1. Use a PCI scan tool to scan all PCI devices in the system. Find out the vendor id and
device id of the missing device.
2. Run B57diag with –seldev option switch to detect the missing device.
e.g. a:\b57diag –b57eng –seldev 14e411677.
3. In B57diag engineering mode, clear the Magic value in the NVRAM.
e.g. 0:>sewrite 0 0
4. Reprogram the Bootcode firmware with "seprg" command.
5. Reboot system if needed.
