Remove OSLDR
The OSLDR application was badly broken and almost impossible to fix with new expanded OS support.

# OSLDR
|
||||
|
||||
RomWBW supports loading new operating systems on-the-fly. For example,
|
||||
if CP/M 2.2 is currently running, you can load and run Z-System from
|
||||
the command line. The `OSLDR` application provides this functionality.
|
||||
|
||||
## Syntax
|
||||
|
||||
`OSLDR [/F] `*`<osimg>`*` [`*`<hbiosimg>`*`]`
|
||||
|
||||
*`<osimg>`* is the name of a file containing an operating system image
|
||||
|
||||
*`<hbiosimg>`* is the name of a file containing an HBIOS firmware image
|
||||
|
||||
`/F` forces operation bypassing compatibility checking
|
||||
|
||||
## Usage
|
||||
|
||||
`OSLDR `*`<osimg>`* will read the specified file, confirm it is an
|
||||
operating system image file, then load it as though it was being
|
||||
booted. For example, `OSLDR ZSYS.SYS` would load the Z-System
|
||||
operating system.
|
||||
|
||||
`OSLDR `*`<osimg>`* *`<hbiosimg>`* will first read and load the
|
||||
specified *`<hbiosimg>`* file as a new HBIOS image and then read and
|
||||
load the specified *`<osimg>`* file. HBIOS image can be produced by
|
||||
the RomWBW build process, but they are not produced by default. You
|
||||
are encouraged to contact Wayne Warthen for more information on this
|
||||
capability.
|
||||
|
||||
## Notes
|
||||
|
||||
The primary function of `OSLDR` is to allow switching to a new
|
||||
operating system while the system if running without a full reboot.
|
||||
|
||||
`OSLDR` is considered generally reliable for when used simply to load
|
||||
a new operating system (one parameter). However, using it to load an
|
||||
HBIOS image is considered experimental and should not be relied upon.
|
||||
|
||||
`OSLDR` can also be used to load "test" versions of operating systems
|
||||
from files transferred to your system. This is especially useful in
|
||||
when loading both an operating system and HBIOS image because you can
|
||||
essentially simulate starting your system with new firmware without
|
||||
reprogramming your ROM.
|
||||
|
||||
`OSLDR` attempts to check the file(s) specified for correctness before
|
||||
loading them, but it is far from perfect. This application should be
|
||||
used with caution and may not work in some cases that are hard to
|
||||
define.
