Install the kernel patch by running the following commands from the kernel source directory: patch -Np1 -i ../linux-2.4.20-packet.patch In the kernel configuration, check your setting with those listed here: Block devices Packet writing on CD/DVD media: Y or M File Systems UDF filesystems support (read only): Y UDF write support (DANGEROUS) Y If necessary, recompile the kernel with make CC=/opt/gcc-2.95.3/bin/gcc dep && make CC=/opt/gcc-2.95.3/bin/gcc bzImage && make CC=/opt/gcc-2.95.3/bin/gcc modules && make CC=/opt/gcc-2.95.3/bin/gcc modules_install Copy /usr/src/linux/arch/i386/boot/bzImage and /usr/src/linux/System.map to /boot. If you utilize LILO edit /etc/lilo.conf appropriately and run lilo. If you build packet writer as a module, add the following to /etc/modules.conf: alias block-major-97 pktcdvd Finally, create the packet driver device nodes in /dev, add one node for every CD-RW drive you want to support: mknod /dev/pktcdvd0 b97 0 mknod /dev/pktcdvd1 b 97 1
