Hello I am trying to recompile the Kernel. http://www.puppylinux.com/development/compilekernel.htm Gives details and tells me it is VITAL to copy the .configure file for puppy in folder /lib/modules. But there is no such file here? I am sure this is obvious once you know, but can anyone point me in the right direction? _________________ Nick See my Puppy webcam Guide at: www.moyo.me.uk/pupplinux |

As of 4.1 it's been moved to /etc/modules. |

here is an instruction to recompile: http://www.murga-linux.com/puppy/viewtopic.php?t=34186 Using a different kernelversion is more complicated, see: http://www.murga-linux.com/puppy/viewtopic.php?t=34341 Mark _________________ my recommended links |

Hello I am most grateful for any help - as what hair I have left I am pulling out!! There are just so many posts on how to do this, it is not too straightforward to follow. I am running latest Puppy 4.1 official release on full HDD install. I managed to (eventually) work out how to get the devx_410.sfs to work on a full hdd installation - as the script does not do this for you 
I downloaded the ready-patched kernel from: http://puptrix.org/sources/kernel-2.6.25.16/ called:
and extracted it to /usr/src/ I read http://www.murga-linux.com/puppy/viewtopic.php?t=34186 that you need to download lzma.458.pet to avoid problems, which I did, although I assume that since I loaded the ready-patched kernel I did not really need to do this? I then followed instructions at: http://www.puppylinux.com/development/compilekernel.htm i.e.
I then got a .config file from [url]linux-2.6.25.16-src-patched_squashfs_unionfs_aufs_lzma_mt.tar.gz[/url]and put it in /usr/src/linux-2.6.25.16/ I did a make menuconfig to check/change options (I also did make oldconfig as this seems to be mentioned too!) then
A few warnings were generated during the compile but these appeared to be mostly minor warnings on pointer types. The build takes quite some time, but I was able to poke a bottle of red wine behind my PC to get it up to room temperature... I then made all the modules and installed these as per above instructions - no errors! The new kernel is called bzImage and was found in /use/src/linux-2.6.25.16/arch/i386/boot It is 22 bytes long. Arrrrrr! Either this is an amazing compression algorithm or... For my HDD install, I was told to copy the newly compiled kernel to /boot and edit the grub loader to give me the option to boot this - which I have done. So what have I done wrong?

Yes - I've spotted it! That file is a LINK, the actual file is at:
I have now copied the 1,666k file, and it booted fine, and WOW, I now have multi core all working! [/code]grep 'processor.*:' /proc/cpuinfo | wc -l

lzma.458.pet yes, this is needed to compress the Kernel. You ran different steps then I did. You should start with the existing .config. Copy /etc/modules/DOTconfig-K2.6.25.16 to /usr/src/2.6.26.16/.config Then run: cd /usr/src/2.6.26.16 make oldconfig (now you have Puppys original configuration, and could edit .config to your needs) make make_modules_install Then copy bzImage to vmlinuz (if it has a correct size, around 2 MB). And compile the aufs.ko module. Mark _________________ my recommended links |
