16.6.23 MultiBoot II Run-Time Services
An OS or application program can access the features of PhoenixBIOS MultiBoot II during run-time by
using the following MultiBoot II Run-Time Services. You can use these services to query the number
and type of Initial Program Load (IPL) devices in the system or display an IPL device menu for speci-
fying the boot priority on the next system restart.
MultiBoot II Run-Time Services are extensions to the Plug and Play run-time functions that implement
the BIOS Boot Specification Ver. 1.01. You can access this specification in Acrobat format from the
Phoenix Web site at:
http://www.phoenix.com/desktop/bbs101.pdf
PnP functions 60h through 6Fh are reserved for the BIOS Boot Specification. See Appendix C of the
Plug and Play BIOS Specification mentioned above for the details of the calling conventions. These
functions are available in Real Mode and 16-bit Protected Mode.
