System Hangup
If your system crashes or hangs due to improper frequency settings, power
OFF your system and restart. The system will start up in safe mode running
at a DRAM-to-CPU frequency ratio of 3:3 and a bus speed of 100MHz. You
will then be led to BIOS setup to adjust the configurations.
NOTE: The function: “CPU Core: Bus Frequency Multiple” is available on
PCB version 1.02 and on.

ler will be disabled. When this field is set to [Disabled], the USB controller
is disabled no matter whether you are using a USB device or not. Configu-
ration options: [Disabled] [Enabled] [Auto]
