1.7.10 PCI Bus 1.0 Speed Switch (S4-2)
This switch can force PCI bus 1.0 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 1.0 bus speed. Set to ON forces PCI bus 1.0 to run at 33 MHz.
1.7.11 EEPROM Write Protect Switch (S3-3)
This switch enables/disables programming of the on-board EEPROMs as a means of protecting
the contents from being corrupted. Set to 1, it disables EEPROM programming by driving the
WP pin to a logic high. Set to ON to program any of the EEPROMs at addresses A0, A6, A8,
and/or AA.
