Does anyone know how in the read/write functions of DOS block device
drivers the starting sector is passed for drives with more than 65536
sectors (of DOS 3.31 or DOS 4.00 or higher)?

My copy of the MS-DOS encyclopedia does not mention about this, only in
the description of the BPB the large drives are mentioned, you know, the
extra 4-byte field with sector count, if the old one is zero.

Thanks for any hint,
Kai Uwe Rommel
