The SCP/DCP-122 includes a 32-bit Flash bank and a PABS site. You may boot the SCP/DCP-
122 from either of these sources. Normally, the SCP/DCP-122 boots from 32-bit Flash.
However, if the Foundation Firmware in the 64-bit Flash is corrupted, you may boot from the
PABS site. Once you have booted the card you may use FFWUPD, FlashProg, or NVMP to
reprogram the 32-bit Flash. You can then power off the card and remove the jumper to allow
local booting. Use the jumper settings described in Table 2.5 to select the bank used for
booting. The location of the jumper is shown in Figure 2.5 below.
