Yes, but it must then replace the flash chip soldered to the
mainboard, so the original chip has to be desoldered. Also the
required equipment for this (a ROM emulator) is currently a bit
expensive at a few hundred dollars. However, the FLASH-PLAICE which
is being developed around a $150 hardware platform could be used once
the software and firmware for the PLAICE is ready.

Did you happen to take a photo of it?

Yep, this is a 4Mbit == 512kb flash chip from our friends at AMD.

Could you identify the packaging? Please see:
