 === NM Cards ===
-The NM cards used in many Cisco products have a Motorola QUICC on them. While the purpose of this is unknown at this time, it is likely that the protocol decode core within the QUICC is used to assist in protocol functions; firmware appears to be loaded into the QUICC at startup time by IOS (via the IOFPGA on the board), but I have yet to capture the firmware being loaded.
+Many NM cards used in the Cisco products contain a conventional PCI ICs. As an example, NM-1FE is built arount AMD PC-Net PCI Ethenet controller, NM-2FE contains two of them. Another "non-intellectual" NM- cards has some sort of PCI bridge and peripheral ICs (serial NMs, ISDN NMs e.t.c.)
 One possiblity is that once Linux/MIPS is booting on this hardware, the QUICCs can be leveraged to improve routing/networking performance of the 3600-series devices if they are to be used in a networking context.

 This is very primitive, however effective and means that code can be executed in place from the flash; the CiscoLoad bootloader actually takes advantage of this with the second stage bootloader essentially running straight from flash.

 = Cisco Systems Routers =
 [[Wikipedia:Cisco Systems|Cisco Systems]] manufactures several routers with MIPS processors. Most of these routers are relatively modern, and sometimes are still prohibitively expensive on eBay or even via alternative channels of purchase. However, as many of these routers get decomissioned, they do appear on eBay at reasonable prices. A popular model with Linux/MIPS developers is the Cisco 3600-series.

-Presently Linux does not boot on the Cisco 3600 series in any usable form. A fairly complete bootloader has been written, and can be found on [http://lebesgue.cowpig.ca/~philippe/cisco-linux Phil's server]. Unless you're looking for something specific, use the latest version of CILO here. Bugginess guaranteed. ;-)
+See [http://linux-cisco.org/index.php/Cisco_3600_Series].

-Do not use versions of CILO prior to 0.4 -- a major bug in the segment loading code caused issues with interrupt handling, among other things.
