298 Part II . Getting Around in Linux Table 8-1 Kernel Parameters Parameter Function init= Sets the initial command to be run by the kernel. By default this is init. nfsaddrs= Sets the NFS boot address, which is used for network booting. nfsroot= Sets the NFS root name, which is used for network booting. no387 Disables the use of the math coprocessor on the CPU. Math Coprocessor Emulation must be enabled in the kernel for this to work. no-hlt Instructs Linux to not use the hlt CPU instruction, which is broken on some older chips. root= Changes the root file system device to the one specified. For example, to mount a floppy disk as the root file system you would use root=/dev/fd0. ro Mounts the root file system read-only so that fsck can fix any errors on the disk. rw Mounts the root file system read/write. This is the default. reserve= Stops a driver from probing the specified IO port region. Some hardware reacts badly to this scanning. mem= Tells the kernel the amount of RAM installed in the system. panic=N Tells the kernel to reboot N seconds after a kernel panic. A kernel panic occurs when a nonrecoverable error happens in the kernel and the entire machine crashes. reboot=[warm|cold] [,[bios|hard]] Sets the type of reboot used when the system is instructed to restart. nosmp Disables SMP support. maxcpus=N Sets the maximum number of CPUs used to N. Configuring LILO LILO is easily configurable through its configuration file, /etc/lilo.conf. The lilo.conf file has many different entries to dictate where and how LILO is installed and how it accesses the operating systems installed on the system. Table 8-2 lists the global entries and Table 8-3 lists the per-image entries.
