PCI Bus 0.0 Speed Switch (S4-1)
This switch can force PCI bus 0.0 to run at 33 MHz rather than the standard method of allowing
the PMC board to control whether the bus runs at 33 MHz or 66 MHz. Set to 1, it allows the PMC
board to choose the PCI 0.0 bus speed. Set to ON forces PCI bus 0.0 to run at 33 MHz.
1.7.9
VME SCON Select Header (J27)
A 3-pin planar header allows the choice for auto/enable/disable SCON VME configuration. A
jumper installed across pins 1-2 configures for SCON disabled. A jumper installed across pins 2-
3 configures for auto SCON. No jumper installed configures for SCON always enabled.
