The following table describes how to update the flash-prom (programmable read-only memory) with the JavaOS operating system by changing the javaos.alwaysUpdate property.
Table D-1 Updating the Flash-prom with JavaOS| If | then | 
|---|---|
| If not set | then the default behavior occurs: if the DHCP-supplied checksum is present and is not zero and does not match the checksum stored in flash, then an Update Flash dialog is displayed. The default value is null. | 
| If set to true | then if the above conditions hold, no dialog is displayed and flash is updated. | 
| If set to any value other than true | then regardless of checksum presence/value, flash is not updated. Note, that if the DHCP checksum is not present or is zero, the flash is not updated. |
