=> R0 = pointer to buffer (must be >= 4k long)
R1 = pointer to disc record describing shape and format
R2 bit 7 set : old directory structure
bit 6 set : old map
R3 = pointer to list of defects
<= R3 = total size of structure created
This call creates a RAM image of a floppy disc map and root directory entry.
The pointer to a list of defects is only needed for new map discs. You don't need to know a FileCore instance private word to use this call; instead the disc record tells FileCore which filing system is involved.
See PRM 2, page 230.
