10.2.2 Non-volatile configuration
There are 2 additional blocks of flash memory used for:
• Non-volatile COM configuration: this block contains the "System COM" setup.
• Retentive values:
Each time a retentive value changes, a record is written in flash, the record is 12 bytes long.
This file is also erased when the flash file system is formatted.
The flash memory can be erased/written minimum 100K times
Each time a retentive value is written, its record is read back and content is verified, in case of error, error code “Write retentive failed”,
code 20517 is generated, it indicates that flash is probably dead.
10.3 Tips for Internet setup
10.3.1 Finding the IP address of a given host
The eWON does provide DNS (Domain Name Server) resolution. But, sometimes, it’s faster to access Internet nodes by its IP address.
In order to find the address corresponding to a given name, you can use the ping –a NodeName command. This command will return
miscellaneous information including the IP address of NodeName that you need.
Example:
The microsoft.com IP address reported is 207.46.197.101 for this example.
10.4 Finding your PC IP address
Under Windows 95/98, the WINIPCFG command (executed from a command prompt or from the START/RUN menu) will return your Ethernet
and PPP adapter IP address. If not currently connected through PPP, the PPP IP address is N/A.
WINIPCFG DOS command does not exist anymore on Millennium, Windows NT, 2000 and XP systems.
The IPCONFIG command can be used instead. This command must be executed from a command prompt and displays as text the IP address of
all the TCP/IP adapters that are detected.
Example:
C:\>ping -a microsoft.com
Pinging microsoft.com [207.46.197.101] with 32 bytes of data:
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
