Motherboard with Backup Chipset

A motherboard with at least one backup chipset, comprising:

• a first chipset;
• a second chipset;
• a central processing unit (CPU);
• a low-speed bus;
• a first switch circuit configured for coupling one of the first chipset and the second chipset to the CPU;
• a second switch circuit configured for coupling one of the first chipset and the second chipset to the low-speed bus;
• and
• a driver configured for switching the first and second switch circuits to be in a backup setup from a normal setup according to states of the low-speed bus and the first chipset,
• wherein the first and second switch circuits couple the first chipset to the CPU and the low-speed bus in the normal setup, and the first and second switch circuits couple the second chipset to the CPU and the low-speed bus in the backup setup.
