memdisk.txt literally indicates, without mentioning CD or that CD would
be harddisk-like (instead of its own category or floppy-like) :
"nopassany Hide all real drives (floppy and hard disk)"
Guess I'm out of luck hiding harddisks when my requirements are:
1) load a floppy image through memdisk
2) use eltorito.sys to mount latest booted ISO9660
3) keep C: free
ad 1 : doable
ad 2 : CD only accessible if harddisks not hidden
ad 3 : no memdisk harddisk image allowed
The only way to guarantee meeting all conditions at the same time is by
preventing DOS from assigning driveletters beyond A: and B: at boottime.
