Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. is provided by IBMBIO.COM for the initialization phase of drivers loaded via DEVICE=/HIDEVICE=/DEVICEHIGH= directives and is only available during these short time intervals. It is called by DR DOS 6.0 EMM386.SYS and Novell DOS 7+ EMM386.EXE to query the size of the BDOS kernel (the resident code of IBMDOS.COM). SeeAlso: AX=12FFh/BX=0001h,AX=12FFh/BX=0002h
