Int 26  - Dos 3.31+ - Absolute Disk Write (32m-2047m Hard-disk Partition)  [D]

   CX = FFFFh
   AL = drive number (0=A, 1=B, etc)
   DS:BX -> disk write packet (see #2240)

Return: CF clear if successful
   CF set on error
       AH = status (see #2235)
       AL = error code (same as passed to INT 24 in DI)
   may destroy all other registers except segment registers

Notes: partition is potentially >32M (and requires this form of the call) if
     bit 1 of the device attribute word in the device driver is set
   original flags are left on stack, and must be removed by caller
   this call bypasses the DOS filesystem, though DOS 5+ invalidates any
     disk buffers referencing sectors which are written with this call
   for FAT32 drives (which may be up to 2TB in size), use INT 21/AX=7305h

Format of disk write packet:
Offset Size    Description (Table 2240)
 00h   DWORD   sector number
 04h   WORD    number of sectors to read
 06h   DWORD   transfer address
