When I test kernels and I want to make a boot floppy, I use this script: ---------- cut ------------- #!/bin/sh # # Created 21-JAN-1995 Richard B. Johnson # cp /usr/src/linux/System.map / cp /usr/src/linux/arch/i386/boot/zImage /tmp/vmlinux ROOTDEV=`df / | cut -d ' ' -f1 | sed -e1d` echo -n 'Setting root device as ' ; echo ${ROOTDEV} rdev -R /tmp/vmlinux 1 rdev /tmp/vmlinux ${ROOTDEV} cp /tmp/vmlinux /dev/fd0 rm -f /tmp/vmlinux psupdate ----------- cut --------------- The first `rdev` command tells the kernel to mount root r/o to start. The second `rdev` command tells the kernel the root file-system to mount. Then the modified compressed image is just copied to what will be the boot-floppy (Drive A:) on startup.
