How Does it Work?

n The basic recipe is this:

n Get the hardware

n Create a programming image

n Write the image to a PCMCIA SRAM card

n Open the access point and insert the SRAM card in place of

the 802.11 PCMCIA card

n Power on the AP

n Short a jumper to boot from the SRAM card and reprogram the

onboard flash

n Watch what happens on the serial port

n Replace the 802.11 card

n You are done

n Now it can be upgraded over the network
