Function transfers data from system memory to internal sector buffer of the fixed adapter INT 13H (0x13) Function 0FH (0x0F or 15) Write sector buffer Function 10H (0x10 or 16) Get drive status

INT 13H (0x13)

Function 0FH (0x0F or 15) >> Write sector buffer

Call with:AH = 0FH
ES: BX = segment: offset of buffer

Returns:If function successful
Carry flag = clear

If function unsuccessful
Carry flag = set
AH = status

Comments:

This function transfers data from system memory to internal sector buffer of the fixed adapter. No data is written to the physical disk drive. This function should be called to initialize the contents of the sector buffer before formatting the drive with INT 13H Function 05H.

INT 13H (0x13)

Function 10H (0x10 or 16) >> Get drive status

Call with:AH = 10H
DL = drive
80H-FFH fixed disk

Returns:If function successful
Carry flag = clear
AH = 00H

If function unsuccessful
Carry flag = set
AH = status
