SYMPTOMS
When booting a 3Com 3Server, the LCD displays &quot;NO OS/2&quot;.



CAUSE
A possible reason for this error is that the settings are not being read correctly from CMOS. According to the 3S500 &quot;Technical Reference&quot;:

If the initial SETUP display does not reflect what you believe to be the actual configuration, you can run the program in a way that allows you to change the configuration values.

CAUTION: Do not use SETUP to change configuration values unless you have specific information on which to base these values. If you are uncertain about the values in the SETUP display, check with your network supplier before altering the configuration.

Another possible cause of the error is that the boot sector has an error. The procedure to follow in this instance is to repartition and reformat the drive with 3FDISK from the 3Server Utility disk.



RESOLUTION
 Establish a 3Com connection.  Type setup/f at the active-console prompt after placing the 3Server Utility disk in drive A, as follows:         a: setup /f You will get a CMOS display. Press Y or N or ENTER at the prompt to verify settings. It may not be necessary to actually change any settings, but you may want to simply verify that the settings are correct.  Press ENTER to exit SETUP and restart the server after checking the servers' MODE and BOOT switch settings. If, after running SETUP, the LCD displays a configuration error, check the 3Server &quot;Technical Reference&quot; manual for possible corrective actions.
