64 kB is enough for SerialICE. I would first check the raid controller
datasheet and PCB if you have more than 16 address lines in the first
Chances are there was something similar on most PCI chipsets, as it was
one practical method for production-line programming in the case of
soldered flash chips. Just don't expect that the possible hardware
bootstrap is labeled or easily accessible on the mainboard.
