Boot disk for reference hard drive for ST/Mega machines

I was reading that the Reference hard drive used the ICD AddSCSI chipset and also read on another site there is a generic boot disk for hard drives that use this interface. Can anyone confirm that this is indeed the case, you don't need manufacturer specific boot disk?

I am curious to know what is on the drive....oh and also try out those hard disk installs of games (which would be great)
