It is from archdetect which comes from the ddetect .udeb. We need to add support for your hardware there. Can you give us the /proc/cpuinfo of those machines, so we can identify it properly ? In any case partman-prep should be installed on all of the IBM machines : all prep (even ppcbug i think), IBM chrps and the newer pseries and what not. > -- > > While looking for the way to set the correct subarch, I found that in > base-installer's postinst, line 438 the CPU variable is filled by: > > CPU=`grep '^cpu[[:space:]]*:' /proc/cpuinfo | cut -d: -f2 | sed 's/^ *//; > s/[, ].*//' | tr A-Z a-z` > > The following case doesn't seem to work with more than one CPU.
