Sorry for posting a message that is a little bit off-topic.

I'm working with a SST 8 Mbit Firmware Hub SST49LF008A flash connected 
to Geode LX LPC bus.
I need to understand where flash registers are mapped in case the flash 
ID is set to 1 (this flash is not the boot flash that has ID=0).
The datasheet just says about identification registers (same thing 
applies for other registers too):

JEDEC ID Registers
The JEDEC ID registers for the boot device appear at
FFBC0000H and FFBC0001H in the 4 GByte system
memory map, and will appear ***elsewhere*** if the device is not
the boot device.

Anybody can tell me what does "elsewhere" stand for in this sentence?
