INT 13 - Ontrack Drive Rocket - SET CYLINDER OFFSET 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 SeeAlso: AX=7B00h
