2-1 System bootstrap
It becomes possible with the MZ-5600 to bootstrap from
the hard disk when the CPM.SYS or MSOOS is stored on
the hard disk, provided that the following restriction is
applicable.
"The system file (CPM.SYS
or MS DOS) can only be loaded
from the physical drive unit number 0 during IPL."
If the CPM.SYS has been stored in the HOO, for instance;

Standard CP/M-86
Fig. 3
The above figure provides the memory map for the ep/M-
86 used on the MZ-5600.
The BIOS consists of the following three blocks:
i) Interface block: Interfaces the BOOS with loes.
ii) loes code block: Control program for the input
output device handler called the
Input Output Control System
(lOeS).
iii) loes data block: Parameter and work area used
~ for the loes.
The MZ-5600 system can be upgraded by using an IN-
STALL command which integrates the optional
loes
module into the BIOS. The above figure on the right
provides the memory map for the upgraded system:
