INT 2fH 4a11H BX=000aH: Set Automount Drives
Expects: AX 4a11H (mux number)
BX 000aH (DoubleSpace fn code)
CX:DX bitmap of drives to enable/disable for automount (see below)
Returns: AX DoubleSpace API Error Code (0000H=success)
CX:DX bitmap indicating previous automount settings
Info: This service is new for DOS 6.2.
This lets you enable and disable automounting for some or all
removable-media drives. In conjunction with INT 2fH 4a11H 000bH,
you can use it to see if automounting is possible.
CX:DX Is treated as a 32-bit bitmap, with the lowest 26 bits each
representing one drive. Bit 0 of DX represents drive A, bit 1 is
drive B...bit 15 is drive P. Bit 0 of CX represents drive Q,
A bit-value of 1 specifies to enable the drive for automounting.
On Entry: CX:DX specifies which drives you want to enable and
disable for automounting.
On Return: CX:DX contains the previous settings.
Notes: ■ If all automounting is disabled (Automount=0 in DBLSPACE.INI),
then this call will have no effect.
■ You can see if automounting is possible by using this fn to
try to enable a drive, then using INT 2fH 4a11H 000bH (query
automount drives) to see if the change was recorded.
