VOID Drvmap(ULONG) | Description: returns a list of mounted drives.
Opcode: 10 (0x000a)
Availability: All TOS versions.
Binding: move.w #$0A,-(sp) trap #13 addq.l #2,sp
Return value: returns a ULONG bitmap of mounted drives. For each drive present, its bit is enabled. Drive 'A:' is bit 0, drive 'B:' is bit 1, and so on.
Definition:Single floppy systems will indicate that two drives are available since both drives can actually be addressed. A request for drive 'B:' will simply cause TOS to ask the user to insert 'Disk B' and provide automatic handling routines for all disk swapping.
