    I am not sure of which format is used for the system
disk.  I presume it is
 commodre SS GCR, so it is compatible with any drive. Nothing further is
 mentioned in my Programmers Reference Guide.  
 No, actually, I think it's the DS GCR format because you need a 1571 to
 boot C128 CP/M. I don't think it can be booted from a 1541, which can only
 read the SS format.  
 Are you sure? I picked up a second-hand C128 recently, and it came with 
 all the manuals (but alas no CP/M disks). The manuals imply that CP/M can 
 be booted from any drive unit (1541, 1570, 1571), so I assume that the 
 disk was in 1541 SS format. Of course to read 'alien' MFM disks you need 
 either a 1570 (which seems to be relatively common over here -- I have 2 
 1570s and no 1571) or a 1571.

 I'd hoped I could run CP/M on it with the drives I have (all of which are 
 single-sided). Perhaps I will have to look for a 1571... 
I'm pretty sure, but to be fair, not 100 percent sure. I've always used a
1571 with mine.
