Above the "UPDATE" section, in your original text, you've got MB instead of GB. In the "UPDATE" section, you might want to clarify that the "They" in "They did not believe" refers to the Snap engineers, not Phoenix32 or myself.

I don't know that the piece in your update about the flash memory being near maximum capacity is correct. Most of the LBA48 stuff is already in the OS image the 4100 runs - the missing piece is the device driver changes, which are quite small. I doubt the image would brow by more than 256 bytes.

At any rate, now I've got an otherwise good 4100 that I'm not sure what I'll do with...I could put one 1TB disk on my Linksys NSLU2, outstrip the 4100's capacity, and still end up with that music server I'd originally wanted.
Yup. 4100's were (mostly*) great for their time, but that was a long time ago. These days, you can beat a 4100's performance with a portable USB HDD plugged into the USB port of the average home router.

* Mostly - there is a glaring oversight in the 4100, as well as the other Snap models from that era - there is no parity protection in memory, so there is a chance of silent data corruption.
