I really haven't read completely through it yet but i think for kernels < 2.6.36 you need to patch them. For 36 and up there has been some type of dockstar support added to the kernel.

Exactly. - soft: only software emulation - softfp + mfpu=xxx: enables the compiler to use FP instructions/registers inside functions, but not as function parameters. This way, code remains compatible with 'soft' libraries - hard: it's a different ABI, where parameters can be passed in FP registers, avoiding expensive moves between core and FP registers. But such code is not compatible with 'soft' libraries. Christophe ___ ARMedslack mailing list ARMedslack@lists.armedslack.org http://lists.armedslack.org/mailman/listinfo/armedslack

The installer gets loaded > into ram and the usb stick is not used after loading; Good news! I finally managed to reboot after installation!!! This time, I reformatted during the install. Upon reboot, uboot (Jeff Doozan's) complained that it did not find /boot/uImage nor /boot/uInitrd. I recreated them, and voila! I guess that during my previous installs withouth reformatting, the installer left dangling symlinks in /boot, and uboot did not manage to handle them properly? I am not really convinced by this explanation because uboot used to go until 'starting kernel', so it did seem to succeed loading it. So to summarize, I think than Richard's procedure should be completed by cd /mnt/sda1//boot ln -s uImage-kirkwood uImage ln -s uinitrd-kirkwood.img uInitrd at least after reformattting. I can give another try without reformatting during install if you want.

[ARMedslack] mfloat-abi
Hi, I did not really understand what's the difference between -mfloat-abi=soft and -mfloat-abi=softfp? Does "soft" always use software floating point and "softfp" could use hardware floating point if a correct -mfpu is given? And why is none of them used in Armed Slack? In my understanding it should be much faster than FPU emulation in the kernel. http://www.arm.linux.org.uk/mailinglists/faq.php#f3 Greetings Thorsten ___ ARMedslack mailing list ARMedslack@lists.armedslack.org http://lists.armedslack.org/mailman/listinfo/armedslack

Just get it off of Jeff site Maybe it's better to be on our own concerning stuff to be downloaded, but I'm not sure.
