#### Boot Disk
To make a CP/M 3 boot disk, you actually place CPMLDR.SYS

system tracks. `CPMLDR.SYS` chain loads `CPM3.SYS` which must

space constraints. You will need to transfer the following files to
your system from the RomWBW distribution directory Binary/CPM3. You
can use XModem for this (or any of the mechanisms in [Transferring
Files].
After this is done, you will need to use `SYSCOPY` to place
the CP/M 3 loader image on the boot tracks of all CP/M 3
boot disks/slices. The loader image is called `CPMLDR.SYS`.
You must then copy (at a minimum) `CPM3.SYS` and `CCP.COM`
onto the disk/slice. Assuming you copied the CP/M 3 boot files
onto your RAM disk at A:, you would use:
- `CPMLDR.SYS`
- `CPM3.SYS` or `CPM3BNK.SYS`
- `CCP.COM`
The `CPM3.SYS` boot file is provided in 2 versions. In the Binary/CPM3
distribution directory, `CPM3.SYS` is the "non-banked" version of
CP/M 3. The `CPM3BNK.SYS` file is the "banked" version of CP/M 3. You
almost certainly want to transfer the banked `CPM3BNK.SYS` version.
After transferring the boot files to your RomWBW system, you will
need to use `SYSCOPY` to place `CPMLDR.SYS` on the boot track of the
target drive. `CPM3.SYS` and `CCP.COM` can be copied to the target
drive using any standard file copy tool such as `PIP` or `COPY`.
You do not need to be booted into CP/M 3 to create or update a CP/M 3
disk. The recommended approach is to boot CP/M 2.2 or Z-System from
ROM. Transfer the boot files to the RAM disk. Then simply copy the
files onto the CP/M 3 disk. Assuming the target CP/M 3 disk is F:, you
can use the following commands to place the files on the target drive:
```
SYSCOPY C:=CPMLDR.SYS
PIP C:=CPM3.SYS
PIP C:=CCP.COM
SYSCOPY F:=A:CPMLDR.SYS
COPY A:CPM3BNK.SYS F:CPM3.SYS

Simeon Cran's ZPM3 is an interesting combination of the features of both
CP/M 3 and ZCPR3. Essentially, it has the features of and
compatibility with both.
Due to this dual compatibility, the ZPM3 distribution image contains
most of the standard CP/M 3 files as well as a variety of common ZCPR3
applications. However, you will notice that user area 0 of the disk has
only a few files. Most of the files are distributed among other user
areas which is standard practice for ZCPR3. Most importantly, you will
see most of the applications in user area 15. The applications can be
executed from any user area because ZPM3 has a default search path that
includes User 15.
The ZPM3 distribution comes with essentially no utility programs at
all. In addition to the standard CP/M 3 utilities, RomWBW includes

You may be surprised to see the file called `CPM3.SYS`. This is not a
typo. Although it is called `CPM3.SYS`, it is ZPM and not the same as
`CPM3.SYS` in the CPM3 directory. Also, unlike CP/M 3, ZPM3 is always
banked, so you will not find two versions of the file. `CPM3.SYS` is a
banked implementation of ZPM3.
After transferring the boot files to your RomWBW system, you will

As previously described, a RomWBW ROM contains ROM applications as well
as a ROM disk image. If you are upgrading your ROM with a new patch
level release, you may wish to upgrade just the application portion of
the ROM. This is referred to as a System Update.
A System Update would involve only updating the BIOS, ROM applications
and CP/M system.

is possible to do a System Update in place of a System Upgrade in some
cases. A System Update would involve only updating the BIOS, ROM
applications and ROM-hosted operating systems.
A System Update may be more favorable than a System Upgrade in cases
such as:
- Overwriting of the ROM drive is not desired.
- Space is unavailable to hold a full ROMWBW ROM.
- To mimimize time taken to transfer and flash a full ROM.
