Comparing boot messages from booting with "good" and "bad" versions of BootX, I saw that the amount of RAM is OK in both cases, but then I found one quite incredible thing, and this is essentially the only difference in the boot messages. Booting with BootX version <= 1.1.3 and any kernel, I get as usual kernel: Calibrating delay loop... 133.12 BogoMIPS Booting with BootX-1.2b2, I get with the same kernels kernel: Calibrating delay loop... 11.39 BogoMIPS This is repeatable, but for me quite incomprehensible. -- Martin ** Sent via the linuxppc-dev mail list.
