1131 Please make sure to pick the right CPU type. Linux/MIPS is not
1132 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1133 *not* work on R4000 machines and vice versa. However, since most
1134 of the supported machines have an R4000 (or similar) CPU, R4x00
1135 might be a safe bet. If the resulting kernel does not work,
1136 try to recompile with R3000.

1982 kexec is a system call that implements the ability to shutdown your
1983 current kernel, and to start another kernel. It is like a reboot

1989 It is an ongoing process to be certain the hardware in a machine
1990 is properly shutdown, so do not be surprised if this code does not
1991 initially work for you. It may help to enable device hotplugging
1992 support. As of this writing the exact hardware interface is
1993 strongly in flux, so no good recommendation can be made.

1999 help
2000 This kernel feature is useful for number crunching applications
2001 that may need to compute untrusted bytecode during their
2002 execution. By using pipes or other transports made available to
2003 the process as file descriptors supporting the read/write
2004 syscalls, it's possible to isolate those applications in
2005 their own address space using seccomp. Once seccomp is
2006 enabled via /proc/<pid>/seccomp, it cannot be disabled
2007 and the task is only allowed to execute a few safe syscalls
2008 defined by each seccomp mode.

2071 The Extended Industry Standard Architecture (EISA) bus was
2072 developed as an open alternative to the IBM MicroChannel bus.
2073
2074 The EISA bus provided some of the features of the IBM MicroChannel
2075 bus while maintaining backward compatibility with cards made for
2076 the older ISA bus. The EISA bus saw limited use between 1988 and
2077 1995 when it was made obsolete by the PCI bus.
