553 can simulate a MIPS32 4Kc system. This patch adds support for the
554 system architecture that currently is being simulated by Qemu. It
555 will eventually be removed again when Qemu has the capability to
556 simulate actual MIPS hardware platforms. More information on Qemu

1175 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1177 of the supported machines have an R4000 (or similar) CPU, R4x00
1178 might be a safe bet. If the resulting kernel does not work,

1906 APM is a BIOS specification for saving power using several different
1907 techniques. This is mostly useful for battery powered systems with
1908 APM compliant BIOSes. If you say Y here, the system time will be
1909 reset after a RESUME operation, the /proc/apm device will provide
1910 battery status information, and user-space programs will receive
1911 notification of APM "events" (e.g. battery status change).
1912
1913 In order to use APM, you will need supporting software. For location
1914 and more information, read <file:Documentation/pm.txt> and the
1915 Battery Powered Linux mini-HOWTO, available from
1916 <http://www.tldp.org/docs.html#howto>.
1917
1918 This driver does not spin down disk drives (see the hdparm(8)
1919 manpage ("man 8 hdparm") for that), and it doesn't turn off
1920 VESA-compliant "green" monitors.
1921
1922 Generally, if you don't have a battery in your machine, there isn't
1923 much point in using this driver and you should say N. If you get
1924 random kernel OOPSes or reboots that don't seem to be related to
1925 anything, try disabling/enabling this option (or disabling/enabling
1926 APM in your BIOS).
