OK, regarding that ol' 2501 that I couldn't load IOS 12.2 or higher unto; due to TFTP checksum errors. I've bandied the two 8MB Flash SIMMs about until I ascertained that one of them was causing problems (wouldn't even load IOS 12.0(8) (got checksum error even then), then I set it aside and installed the other SIMM in Slot 0; IOS 12.0(8) loaded fine).
I had a third, as-yet-unused 8MB SIMM lying around, and I DO want to have 16MB Flash so I can load 12.3 and do IPv6 routing, so I installed that third SIMM in Slot 1. Now at boot-up I get this message:
This typically points to a bad SIMM (assuming the second chip really is an 8 MB SIMM). The device has detected one SIMM (2 in this case) at the wrong size. I'd say have them RMA'd, but in this case, perhaps another trip to eBay might score you some better chips.
