On Cobalt servers, these machines have a much less capable firmware installed on chip. The Cobalt BOOTROM is primitive, by comparison to the SGI PROM, and has a number of serious limitations.
 * There's a 675kB (approximate) limit on kernels. The current size of Linux 2.4 makes it nearly impossible to make a kernel this size. Linux 2.6 and 3.x is totally out of the question.
 * 64-bit kernels are not supported by the stock firmware (although these are highly experimental on Cobalt machines at this time)
 * The shell is basic at best
