A technician purchases a new 120 GB IDE hard disk to use in an old server as a swap drive. After adding the drive to the server， the technician discovers that the operating system does not detect the drive.  
After rebooting the server， the technician notices the drive is missing from POST and comes to the conclusion that the BIOS needs to be updated. The technician downloads the latest version of the BIOS update from the manufacturer website.  
Which action should the technician take next？（）

A customer wants to increase the performance of an existing server. They are running a very network intensive application and feel that increasing the bandwidth to the network will fix their problem. 
They are running two 24-port autosensing 10/100 hubs， tied together with a standard Ethernet crossover cable in port 24. 
The server is running IPX. After adding a second network card and plugging one card into each hub， they have not seen any performance improvement. 
Which two are likely reasons why implementing network adapter teaming has not improved performance？（）
