Int 13 Fn EF - Ontrack Drive Rocket - Set Cylinder Offset [c]
AH = EFh
CX = cylinder offset for next INT 13 call
DL = drive number (80h, 81h)
Return: CF clear
AH = 00h
Program: Drive Rocket is a drive accelerator by Ontrack Computer Systems for
IDE drives supporting the read multiple and write multiple commands
Desc: the following INT 13 call will add the number given by this call to
the specified cylinder to get the actual cylinder number, then reset
the offset to zero
Note: this function is also supported by the NOW! disk cache, and presumably
newer versions of SWBIOS and Disk Manager
for software which supports this call, AH=EEh is equivalent to calling
this function with CX=0400h
the cylinder offset is reset to 0 by all INT 13 called except AH=EEh
and AH=EFh
See Also: AX=7B00h
