Hardware Setup
JP16: PCI Bus Asynchronous/Synchronous Jumper
Asynchronous and synchronous (default) PCI bus frequency settings are
available.
PCI Bus Setting
Asychronous
Synchronous
Divides the host bus by 2 to get the Asynchronous setting, and sets the
PCI bus on 32MHz to get the synchronous setting. Set JP16 to
Synchronous mode when the system is unstable.
Host Bus
(CPU Bus)
50 MHz*
55 MHz*
60 MHz
66 MHz

*: Do not use Asynchronous setting when the host bus frequency is
50MHz or 55MHz.
**: Do not use Synchronous setting when the host bus frequency is 75
MHz.
