33/66MHz operation.

["GEORGE, Peter (Newcastle)" <Peter.George@leoniwiring.co.uk>]

Hi all,

I have designed a PCI expansion card which utilises an Oxford Semiconductor
OX9160 bridge chip. This is a 33 MHz device, fully compatible with version
2.2 of the PCI Spec. The PCI card itself has the 5V footprint. According to
the specification, this makes my card incompatible with 66MHz operation.
They have only ever been installed into PCs with 33MHz PCI buses.

However, inadvertantly, my colleagues have intalled my boards into PCs with
66MHz buses. The boards are now not operational. Is it likely that
installing my boards into a 66MHz bus would fry the PCI chips?

Many thanks,
