 I ran make and copied the payloads from the ''buildrom/deploy'' directory to my s2892 to be used. ''olpc-payload.elf.lzma'' (732K) is used for booting directly from LinuxBIOS, and ''olpc-payload-uncompressed.elf'' (1.7M) was useful for testing it with FILO and Etherboot.

 Because the kexec tools that are included with OLPC's buildrom are stripped down for 32-bit kernels, I built kexec statically linked (read "large file") and put it on the hard drive with the kernel to be loaded.  I use kexec to boot my kernel which has been combined with initrd into an elf with mkelfImage:
-  mkelfImage --comand--line="ro root=/dev/hda1 console=tty0" --kernel="" --initrd="" --output="mylinux.elf"
+  mkelfImage --comand--line="ro root=/dev/hda1 console=tty0" --kernel="vmlinux" --initrd="initrd" --output="mylinux.elf"
 I have to use
   kexec -f mylinux.elf
 because otherwise kexec calls shutdown and there is no shutdown in the OLPC initrd.  I guess that's a half truth, because when I call kexec without the -f it reboots the machine completely instead of a kexec when shutdown is available.
