INT 13h, 0Dh (13) Alternate Disk Reset fixed disk
Resets the fixed disk controller and drives, forcing recalibration of
the read/write heads. This service can be performed on fixed disks
only.
On entry: AH 0Dh
DL Drive number (Bit 7 must be set)
Returns: AH Status of operation (See Service 01h)
CF Set if error, else cleared
--------------------------------------------------------------------------
Notes: See Service 00h for a more generalized version of
this service.
A fixed disk reset is only executed if the value in
DL is less than or equal to the last fixed disk on
the system. That is, the lower 7 bits of DL should
be less than or equal to the number of fixed disks.
For the AT, XT-286, and PC Convertible, the BIOS
executes INT 15h, Service 90h (Device Busy), for the
diskette (Type = 01h) and the fixed disk (Type =
00h) prior to waiting for the interrupt. INT 15h,
Service 91h (Interrupt Complete), is executed upon
completion.
