I don't know about the 74xx support in PPCBoot, but PPCBoot sets up the 107 in a MCP8245 on a Sandpoint X3 well-enough to boot linux. PPCboot does not, however, configure more than one 'bank' on the SO-DIMM socket, and does not (currently) read the SPDs, if only for the lack of proper I2C support (at least for the 824x). YMMV. My question is how have_of got set: arch/ppc/mm/init.c: if (!have_of) FREESEC(openfirmware); Otherwise... On the whole "'reset/reboot' the system" thread, I'm interested in similar solutions for the 824x, since I'm having highly similar problems on reboot. :-) Interestingly, the 'gorom' solution works fine for me, as long as my root filesystem is not jffs2, then only if / is mounted 'rw'. romfs, cramfs, nfs, or jffs2 (read-only) all reboot just fine. -- "Perl is basically TECO-99." ---Barry Shein ** Sent via the linuxppc-embedded mail list.
