[. . . ] This is the same encryption rate that is used by the Windows XP operating system, and was selected in order to align it closer to the wireless LAN standard. Outside of wireless LAN environments, encryption is generally set at either 64 bit or 128 bit. However, the wireless LAN standard requires that 24 bits be reserved for fixed data. As a result, the user can only use 40 bits (64 minus 24) or 104 bits (128 minus 24) for encryption. This requirement also fixes the number of characters used for 128 bit encryption to 13 which is calculated as (13 x 8 bits = 104). Create Keys with Passphrase Passphrase Create Keys Manually (Hexadecimal Input) Not supported. Not supported. Select this to use hexadecimal character codes to set the encryption keys (Keys 1 - 4). Enter a 10-digit value when you have selected [40 bit]* for the encryption. Enter a 26-digit value when you have selected [104 bit]* for encryption. Select if the network contains a card that is set with the encryption key using the character code. Specify the encryption keys with the same value used for other wireless LAN cards that are already set. NETWORK CONNECTION: WINDOWS 2000 The section describes how to set the network connection for a computer with Windows 2000. Network Settings In this section, you set "TCP/IP Settings, " and complete "Checking Computer Name and Workgroup, " required for the network connection.

ASCII Input Select to use the ASCII codes to set encryption keys (Keys 1 - 4). Select this if network does not contain other wireless LAN cards that are set with encryption key using character codes. Enter a 5-digit value when you have selected [40 bit]* for the encryption. Enter a 13-digit value when you have selected [104 bit]* for encryption. You can use the following characters: 0 - 9, A - Z, a - z, _ (underscore). For example, to set "ABC12" for the encryption key, enter "ABC12. " Default Key Click the down arrow, and select a key from Keys 1 - 4. Ask your network administrator to check the setting. Item For AdHoc Network Description Set the IP address and subnet mask: Click [Use the following IP address], and enter a value for [IP address] and [Subnet mask].

[. . . ] Data stored in this way can not be changed by your LifeBook notebook and does not require power to maintain it. Shadow RAM A technique of copying data or applications stored in ROM (Read Only Memory) into RAM (Random Access Memory) for access during actual operation. RAM is much faster to access than ROM, however ROM contents are not lost when power is removed. Shadowing allows permanently stored information to be rapidly accessed. [. . . ]
