I realize that this question has been posted several times in various ways, however, I have been unable to find a posted solution to the issue. It has been some time since the question was raised and I am currently facing a situation where I need to find a copy of a firmware image for an old Catalyst 1900 series switch. The only version number I can find to reference for the firmware is 5.37 (but any 5.x version would do I think - provided it is the standard edition firmware). I have tried contacting Cisco at their US 800# and have just been shuffled around. At one point I was told to email web-help@cisco.com, but that address has proven unresponsive. If anyone knows where I can locate a stored image of this firmware I would greatly appreciate some guidance!
