System Profiler (and presumably the system at large) sees the card, but the flasher utility doesn't. When I try launching it, it says "There is no card for this utility to update." Given this, I must assume that the utility somehow determines if there's a card it can flash by looking for something in the now non-existent firmware.

I'd be willing to send this card off to someone who knows what they're doing, if I fail all attempts at fixing it myself.

But keep the advice coming in! I might yet learn for myself how to fix it!

p.s. Is it possible to do a raw firmware write on the Mac by using the Terminal? Or perhaps Linux?

EDIT: I think I found the bare firmware file. It is 136 KB in size. Does this sound right?
