Installing on a Compact Flash

Hi guys,
I’ve try to install Mikrotik on asus motherboard with p4 processor with a cf-ide adapter, but after the installation the system doesn’t boot; it say “unable to boot from device, insert a boot disk and retry again”.
How can i solve it?

Thank you

Have You checked settings in bios? Everything’s ok there?

I’ve setting the IDE controller in Compatible Mode (default is Enhanced), and then?
There are some special tricks to do?

Please say me how!
Thanks
