Jared,

What you say makes sense, but when Rodney said RSP4+ supported it but RSP4 did not, that confused me because certainly at the very least I guess its documented in the release notes that the boot code supports ATA.

Also, I thought the only real changes between RSP4 and RSP4+ was the addition of parity memory, apparently there is more too it, or what we are talking about is some sort of crippleware that looks for the hardware id and makes a feature work or not work.

No, this is a feature of the ROMMON.

I'm not sure if the rommon is socketed, but i suspect that later versions of the rsp4 support it, but not all, hence the documentation and official support say no :)

if you have a eeprom burner you could probally copy it, but you would run into copyright law issues as you are likely not authorized to do so..

I ran into this issue as we were attempting to upgrade some of our cisco devices, and they said we needed the rsp4+ or rsp16 to do the ata.. instead we decided to decomm the routers for numerous reasons, this being one of smaller issues, and migrate everything to a 7200 in these locations instead. It didn't provide the same "redudndancy" as you could get in a 7500 w/ dual RPs, but the dual RP situation in the 7500 isn't that great anyways as you need a cbus stall.. (none of this is news :)

anyways, hope this helps make things a bit more clear for those of you out there.. cisco won't "support" it, but it's possible to make it work..

just don't expect them to help you out with flash failures if you have them, but if you're smart enough to do this, there is a chance you won't be calling them for such a simple issue.. but make sure you document it internally, so that if you ever leave or are replaced your company doesn't hate you after the fact that you're using an "unsupported" config when they run into trouble.. :)
