| + | For a loader.o loadable kernel, the build procedure is slightly different. First, check [[howto:hdd_boot|How to install a root file system to a Hard Disk]] for some additional kernel patches. Then, | ||
| + | make oldconfig;make clean;make dep;make | ||

| + | You could also build the modules, because the default .config specifies modular USB support among other items: | ||
| + | make modules | ||
| + | make modules_install INSTALL_MOD_PATH=/tftpboot | ||
| + | The installation command will "fail" because it will attempt to use your buildhost's 'depmod' utility to construct a modules.dep file. However, the modules themselves will be installed into /tftpboot/lib/modules/2.4.21-pre4/. Also, do not be surprised that the default .config builds several inappropriate wireless drivers (orinoco, hermes): these can't be used by the dsmg600 (unless you happen to have a miniPCI card supported by those drivers, and swap out the shipped Ralink RT2560). | ||
