The problem is that the Startup parameter on the Disk Mode page is set to a SCSI ID number or to Floppy, and you do not have a Boot Macro on the specified disk. If you set it to Off, these messages will not show up when you turn on the unit.

A Boot Macro is a macro named Boot, located at the root level of a disk, which will load automatically when you turn on the unit. By setting the Startup parameter to a value other than Off, you cause the Kurzweil to look for a file called BOOT.MAC on the root level of the specified disk and load that file when you turn on the unit.

If you have created a Boot Macro and still see these messages, check to make sure the Boot Macro is saved at the root level on your disk, and that Startup is set to the correct SCSI ID number of your drive (or to floppy if you are using that instead).
