CAUTION: If the available free space on the flash drive is reduced to below 3 MB, the computer becomes unstable.

A write filter is used by the computer for security and to prevent excessive flash write activity. Changes to the computer configuration are lost when the computer is restarted unless the write filter cache is disabled or a -commitcommand is issued during the current boot session. Refer to Chapter 2, “HP Write Filters,” for additional information.

Saving files

The computer uses an embedded operating system with a fixed amount of flash memory. HP recommends that you save files that you want to retain on a server rather than on your computer. Be careful of application settings that write to the C drive, which resides in flash memory (in particular, many applications by default write cache files to the C drive on the local system). If you must write to a local drive, change the application settings to use the Z drive. To minimize writing to the C drive, update the configuration settings.

Mapping network drives

To keep the mappings after the computer is restarted, follow these steps:

1.Disable the write filter cache during the current boot session or issue the –commitcommand.

2.Click Reconnect at logon.

Because a user logon cannot disable the write filter cache, you can retain the mappings created by a user by logging off the user (do not shut down or restart the computer) and logging back on as administrator, and then disabling the write filter.

You can also assign the remote home directory by using a user manager utility or by other means known to administrators.

Roaming profiles

Write roaming profiles to the C drive. The profiles need to be limited in size and will not be retained when the computer is restarted.

NOTE: For roaming profiles to work and be downloaded, there must be sufficient flash space available. In some cases it may be necessary to remove software components to free up space for roaming profiles.
