I recently acquired and IO. Found it really easy to open. I think its a V5 - here is whats in it:
A Rise 266 cpu, SW3 and SW4 switches, no epoxy to be seen anywhere (bios chip pops out easily), complete intact ide header, complete intact (what appear to be) serial headers. The model # on the case is NP1000.
Can anyone help me determine which version this is? Also, I've tried several of the keyboard shortcuts to get into the bios, get login prompt, etc with no luck. Any suggestions?
