INT 13 - DISK - GET DRIVE PARAMETERS (PC,XT286,CONV,PS,ESDI,SCSI)
AH = 08h
DL = drive (bit 7 set for hard disk)
Return: CF set on error
AH = status (07h) (see AH=01h)
CF clear if successful
AH = 00h
BL = drive type (AT/PS2 floppies only)
01h 360K
02h 1.2M
03h 720K
04h 1.44M
06h ??? (checked by 386MAX v6.01)
CH = low eight bits of maximum cylinder number
CL = maximum sector number (bits 5-0)
high two bits of maximum cylinder number (bits 7-6)
DH = maximum head number
DL = number of drives
ES:DI -> drive parameter table (floppies only)
Notes:  may return successful even though specified drive is greater than the
number of attached drives of that type (floppy/hard); check DL to
ensure validity
for systems predating the IBM AT, this call is only valid for hard
disks, as it is implemented by the hard disk BIOS rather than the
ROM BIOS
Toshiba laptops with HardRAM return DL=02h when called with DL=80h,
but fail on DL=81h.  The BIOS data at 40h:75h correctly reports 01h.
