Routine Description:
This routine is the c routine called from the ROM. It must be placed
at the beginning of the C code because the ROM copies the code from this
point to the end and then jumps to it.
This has a different calling interface than the Jazz code.
Arguments:
Cause 0 on a normal reset/powerup.
1 on a softreset.
ProcessorInfo Pointer to processor information block.
Valid only if Cause = 0.
SystemInfo Pointer to system information block.
Valid only if Cause = 0.
Return Value:
Never returns.

Routine Description:
This function gets control from the serial ROM if the serial ROM
detects a corrupted VMS Console boot image. (In actuality, the

Arguments:

Unused1 the firmware.
SystemInfo Contains Alpha_AXP information from the PALcode.
Since this module is only executed on a hard reset,
there is no need to check the "Cause" argument.
