Brief
SET LOGICAL DRIVE MAP
Family API
Input
AX = 440Fh BL = physical drive number (00h=default,01h=A:,etc))
Return
CF set on error AX = error code (01h,0Fh) (see #01680 at AH=59h/BX=0000h) CF clear if successful drive now responds to next logical drive number
Macro
Notes
maps logical drives to physical drives, similar to DOS's treatment of
a single physical floppy drive as both A: and B: DR DOS 3.41-5.0 DRIVER.SYS does not support drive mapping and thus always returns an error on this function
