CC1000dm Setup

If the Serial ROM (SROM) is enabled, it overrides the 16-megabyte window with the
applicable window. Install this jumper when using the SROM and also when the S-Port
ready and P-Port ready bits are to be set. This allows the bridge to be enumerated with-
out any further interaction.
OSCILLATOR SELECTION
When the 66 MHz oncard oscillator is enabled, this allows the CC1000dm to produce its
own 33/66 MHz clock for the secondary side. This is independent of the primary fre-
quency.
BRIDGE SERIAL ROM SELECTION
Installing the bridge SROM jumper disables the PCI 6254 bridge SROM. The EEPROM is
used to initialize the registers. If the EEPROM becomes corrupted and locks the system,
disabling the EEPROM allows default access to the CC1000dm.
