[syslinux] Unable to figure out extlinux

[Pete]

OK, been perusing the archives and Google, but can't find what I want. 
I'm building up a 512 MB compact flash using the CLFS directions to 
build the filesystem. That works great, but I would like to use extlinux 
to make the cflash bootable on my little SBC. However, to date, no dice. 
Attached is my extlinux.conf file and the steps I have used to make this 
work.

Initially I tried to put everything in /boot and point the conf file 
there. No errors when running extlinux, but I get a bad or missing OS 
error when I try to boot it. I fiddled with the conf file, tried again, 
same problem. Moved everything from /boot to /, and same error. I know 
I'm missing something, but I'm not sure what. Another thing I tried was 
to copy the mbr.img to the disk, but that didn't help. Some details

[root at tyr Murano]# cat extlinux.conf

Any help would be appreciated. Thanks.
