]] You've got a point there, I didn't knew about that. To access a CD-ROM i
] need the programs ccd.com (to enter a directory), ccopy.com (to copy files
] from CD-ROM to eg Harddisk) and cdda.com (to start/stop/.../pause an
] audio-CD)
] I always thought that they were only necessary to deal with the
] FAT12-problem
Normal CD-ROMs use an entirely different filesystem. They do not use FAT but 
they use ISO9660 filesystem. That is the reason why you need those special 
program to navigate through the CD and why you need special drivers to 
directly use CD-ROM with the MEGASCSI and some other interfaces.

I think that your idea to put a fat image on your CD will not help you, since 
the CD-ROM drive will not recognize the data CD and therefore not pass the 
data on to the SCSI interface. It will simply return an error code like 
'illegal CD' or 'unformatted CD' or something like that. But I'm not sure 
about this. You can always try it. Perhaps you can start by simply making a 
copy of your current MSX harddisk to a CD to see if the whole concept works. 
In that case you do not have to worry about making the partition table and 
everything because you already copy a proper partition table from your 
harddisk.


Kind regards,
