Does anyone know how to set the FSB to 66Mhz on HP Vectra Vei8 PCs with Sherwood-B motherboards?

A “CPU Frequency Jumper” block is located on J14 and the manual states a CPU will come with a matching shunt if needed but that is all I could find on it.

Being a 440ZX board it should be possible to set this to 66MHz FSB but I can not figure out thia undocumented setting.

Assuming Slot 1, on mine its silkscreened above the memory slots

Thank you so much, PCHP to the rescue yet again! 🤣

Aren't those just the multiplier jumpers, not FSB?

I would expect OEM boards like this to 'autodetect' FSB via BSEL0 and BSEL1 pins on the CPU. Both should be pulled low for 66MHz.
