  this matches my info-digging around an 2940UW I found in the dumpster:
it came off a PC-only-oriented industry and sports a flash chip of some
size.

  my intention was to flash it for apple machines, but I found out that
mac variants of 2940's need a flash of double size 
  (sorry forgot exact figures and links... shame on me)

  by "involves a soldering iron" did you mean "remove the small, put in
the big" flash-rom chip?
  this would match my intention I never came to implement

  I'd expect the flash utility would prevent from havocking a 'small flash'
adapter board with the larger firmware, but one never knows...

  sun/ultrasparc specific ROM image? dunno.
  apple specific ROM-image? I meant it to be available from adaptecs
website, obviously packed into a mac-usual archive
