I knew that TiVo ran Linux, but I was under the impression that Tivo was
an x86 platform. If it is indeed a 403xx, I stand corrected. Where does
the kernel support lie for it? It's not in the 2.3.21 tree or the vger
The difference between the 403A, B, C, GC, and GCX variants are the
quantity of I- and D-cache, the presence or lack of an MMU, the presence
or lack of an on-chip serial port, and the number of DMA channels.
