Int 13h, 07h Format Disk Starting at Cylinder fixed disk
Initializes each sector on a specified cylinder and all subsequent
cylinders with sector address and size information. Only XTs may
use this service.
Entry AH = 07h
AL = Interleave value
CH = Cylinder number (10-bit value; upper 2 bits in CL)
DL = Drive number (Bit 7 must be set)
Return AH = Status of operation (See Service 01h)
CF Set if error, else cleared
------------------------------------------------------------------
Note
This service will destroy all previous contents of the disk.
The cylinder number is a ten-bit quantity (0 through 1023). Its
most significant two bits are in bits 7 and 6 of CL; the remaining
eight bits are in CH.
If an error is encountered, use Service 0h to reset the drive and
retry the operation.
