bootimg.bbclass - This creates a bootable image using syslinux, your kernel and an optional initrd
syslinux.bbclass - This creates a configuration file suitable for use with syslinux.
db1200.conf geodelx.conf - add db1200 and geodelx machine configurations.
Forgot the mt-add on these in the last attempt...
