|

.Sh DESCRIPTION
|
||||
.Nm Doscmd
|
||||
can either emulate a subset of DOS and run the
|
||||
single command
|
||||
.Ar cmd
|
||||
.Ar args ,
|
||||
or it can be used to emulate a PC and boot DOS,
|
||||
which allows it to run a larger variety of DOS applications.
|
||||
It should be noted that MS DOS 6.2 and higher appear
|
||||
to cause difficulties for
|
||||
.Nm doscmd.
|
||||
To boot DOS, either provide the
|
||||
.Fl b
|
||||
flag or omit the
|
||||
.Ar cmd
|
||||
argument.
|
||||
If
|
||||
.Fl b
|
||||
is specified,
|
||||
.Ar cmd
|
||||
and
|
||||
.Ar args
|
||||
are ignored.
|
||||
.Pp
|
||||
Although
|
||||
.Nm doscmd
|
||||
only provides a subset of DOS, it is sufficient to run a variety of
|
||||
programs, including, but not limited to, compilers, assemblers and
|
||||
linker-loaders.
|
||||
.Pp
|
||||
The various flags available to
|
||||
.Nm doscmd
|
||||
are:
|
||||
.Bl -tag -width indent
|
||||
.It Fl 2
|
||||
Enable debugging traces of every trap to the
|
||||
.Nm doscmd
|
||||
emulator from the DOS program.
|
||||
Note that some traps are handled in the kernel and hence will not
|
||||
be traced.
|
||||
.It Fl 3
|
||||
Enable debugging of several lower level functions, such
|
||||
as changing of interrupt vectors and initializing paths to logical drives.
|
||||
.\"
|
||||
.\"
|
||||
.\"
|
||||
.It Fl A
|
||||

|
||||
This is the same as using the

Cause

to pause just prior to jumping to the DOS program.

Very little use except for developing

.Nm doscmd .
|

.El
|
||||
.Pp
|
||||
When starting up,
|
||||
.Nm doscmd
|
||||
attempts to read a configuration file. First the file
|
||||
.Cm .doscmdrc
|
||||
in the current directory. If not found there, the
|
||||
.Cm $HOME
|
||||
directory is searched. If still not found, the file
|
||||
.Cm /etc/doscmdrc
|
||||
is used.
|
||||
.Pp
|
||||
In the configuration file, a comment is started with the \fB#\fP character.
|
||||
Blank lines are ignored.
|
||||
Non empty lines either are environment variables
|
||||
or commands which configure devices.
|
||||
Any line which has an \fB=\fP before any white space is considered to be
|
||||
an environment variable assignment and is added to the DOS environment.
|
||||
The rest of the lines are one the of the following

A disk's geometry can either be directly specified with

being the number of cylinders,
|

.Ar head
|

the number of heads and

the number of sectors per track,

(see below).
|
||||
The option
|
||||
.Ar fdisk_tab
|
||||
argument specifies file to use as the first sector
|
||||
of this disk. This can be useful for inserting a
|
||||
false fdisk table when
|
||||
.Ar path
|

only refers to part of a disk.

|

Cause doscmd, when emulating DOS, to report
|
||||
.Cm version
|
||||
as the version number of DOS when called from the program named
|
||||
.Cm command .
|
||||
The format of
|
||||
.Cm version
|
||||
is the same as of the
|
||||
.Cm MS_VERSION
|
||||
variable described below.
|
||||
.El
|
||||
.Pp
|
||||
If not already assigned,
|
||||
.Cm C:
|
||||
will be assigned to the root directory (/) and the current directory
|
||||
for
|
||||
.Cm C:
|
||||
will be set the the actual current directory.
|
||||
Note that this means that invocations such as:
|
||||
.sp
|
||||
doscmd ../foo
|
||||
.sp
|
||||
will not work as the
|
||||
.Cm C:
|
||||
directory will start with the current path.
|
||||
Also, the following environment variables will be defined if not
|
||||
already defined:
|
||||
|
||||
.nf
|
||||
.Cm "COMSPEC=C:\eCOMMAND.COM
|
||||
.Cm "PATH=C:\e
|
||||
.Cm "PROMPT=DOS>
|
||||
.fi
|
||||
|
||||
The
|
||||
.Cm PATH
|
||||
variable is also used to find
|
||||
.Ar cmd .
|
||||
Like DOS, first
|
||||
.Ar cmd.com
|
||||
will be looked for and then
|
||||
.Ar cmd.exe .
|
||||
.Sh "CONFIGURATION VARIABLES"
|
||||
.Pp
|
||||
There are several variables in the
|
||||
.Cm .doscmdrc
|
||||
file which are internal to doscmd and do not actually get inserted into
|
||||
the DOS environment. These are:
|
||||
.Bl -tag -width MS_VERSION
|
||||
.It Cm MS_VERSION
|
||||
The value of this variable is used to determine the version of DOS that
|
||||
should be reported by
|
||||
.Nm doscmd .
|
||||
Note that
|
||||
.Nm doscmd
|
||||
will not change the way
|
||||
it works, just the way it reports. By default this value is
|
||||
.Cm 410 ,
|
||||
which corresponds to
|
||||
.Nm "MS DOS
|
||||
version
|
||||
.Nm 4.1 .
|
||||
To change it to version 3.2 (the default in previous versions of
|
||||
.Nm doscmd )
|
||||
use the value of
|
||||
.Cm 320 .
|
||||
.El
|
||||
.Sh FILE TRANSLATION
|
||||
.Nm Doscmd
|
||||
translates
|
||||
.Nm BSD/OS
|
||||
file names into
|
||||
.Nm DOS
|
||||
file names by converting to all upper case and eliminating any invalid
|
||||
character. It does not make any attempt to convert ASCII files into
|
||||
the
|
||||
.Cm <CR><LF>
|
||||
format favored in the DOS world. Use the program
|
||||
.Xr bsd2dos 1
|
||||
to convert ASCII files.

.Sh INSTALLING DOS ON A PSEUDO DISK
|
||||
.Pp
|
||||
To install DOS on a pseudo hard disk under doscmd, do the following:
|
||||
.Bl -tag -width XXXX
|
||||
.It 1
|
||||
Create a
|
||||
.Pa .doscmdrc
|
||||
with at least the following:
|
||||
.Bd -literal -offset indent
|
||||
assign A: /dev/rfd0_1440_3.5 1440
|
||||
assign A: /dev/rfd0_720_3.5 720
|
||||
assign hard boot_drive 80 2 2
|
||||
.Ed
|
||||
.Pp
|
||||
You may need to adjust the raw files for the A: drive to match
|
||||
your system. This example will cause the HD drive to be tried
|
||||
first and the DD drive second.
|
||||
.Pp
|
||||
Note that you should only use raw devices or files at this point,
|
||||
do not use a cooked device! (Well, it would probably be okay
|
||||
for a hard disk, but certainly not the floppy)
|
||||
.Pp
|
||||
.Li boot_drive
|
||||
should be the file name of where you want your bootable
|
||||
image to be. The three numbers which follow
|
||||
.Li 80 2 2
|
||||
say that the drive will have 80 cylinders, 2 heads and 2 sectors per track.
|
||||
This is the smallest drive possible which still can have MS DOS
|
||||
5.0 installed on it along with a
|
||||
.Pa config.sys
|
||||
and
|
||||
.Pa autoexec.bat
|
||||
file.
|
||||
.Pp
|
||||
You might want to create a larger boot drive.
|
||||
.Pp
|
||||
The file
|
||||
.Pa boot_drive
|
||||
must exist, so use the command touch to create it.
|
||||
.It 2
|
||||
Insert a floppy disk into the A: drive which is bootable to MS-DOS
|
||||
and has the commands fdisk, format and sys on it. You should also
|
||||
copy the file instbsdi.exe onto the floppy by either mounting it
|
||||
with the msdos file system type or by using mtools
|
||||
(e.g.,
|
||||
.Li mwrite instbsdi.exe a: ).
|
||||
.It 3
|
||||
run doscmd.
|
||||
.It 4
|
||||
At the > prompt type
|
||||
.Li fdisk .
|
||||
.It 5
|
||||
Select
|
||||
.Li Create DOS partition or Logical Drive .
|
||||
.It 6
|
||||
Select
|
||||
.Li Create Primary DOS Partition .
|
||||
.It 7
|
||||
Tell it how big to make it
|
||||
(Typically the whole drive. It is pretty tiny after all.)
|
||||
.It 8
|
||||
Get out of FDISK by hitting
|
||||
.Li <ESC>
|
||||
a few times.
|
||||
.It 9
|
||||
doscmd may abort, if it does, start up doscmd again.
|
||||
.It 10
|
||||
At the > prompt, type
|
||||
.Li format c:
|
||||
and follow the instructions.
|
||||
.It 11
|
||||
At the > prompt type
|
||||
.Li sys c: .
|
||||
.It 12
|
||||
Get out of doscmd.
|
||||
.It 13
|
||||
Either remove the floppy from the drive or add the line
|
||||
.Bd -literal -offset indent
|
||||
boot C:
|
||||
.Ed
|
||||
to your
|
||||
.Pa .doscmdrc .
|
||||
.It 14
|
||||
You should now be running DOS off of your new disk. You will
|
||||
probably want both config.sys and an autoexec.bat file. To
|
||||
start with, you can say:
|
||||
.Bd -literal -offset indent
|
||||
> copy con: config.sys
|
||||
LASTDRIVE=Z
|
||||
^Z
|
||||
> copy con: autoexec.bat
|
||||
@echo off
|
||||
instbsdi.exe
|
||||
^Z
|
||||
.Ed
|
||||
.It 15
|
||||
Quit doscmd.
|
||||
.It 16
|
||||
You know have a bootable pseudo disk which will automatically call
|
||||
the magic
|
||||
.Li instbsdi
|
||||
program, which installs BSD/OS disks. To use
|
||||
them add lines to your .doscmdrc such as:
|
||||
.Bd -literal -offset indent
|
||||
assign D: /usr/dos
|
||||
assign P: -ro /usr/prb
|
||||
.Ed
|
||||
Not that you will not always be able to access every file due to
|
||||
naming problems.
|
||||
.El
|
||||
.Sh DIAGNOSTICS
|
||||
.Pp
|
||||
If
|
||||
.Nm doscmd
|
||||
encounters an interrupt which is unimplemented, it will print a message
|
||||
such as:
|
||||
.sp
|
||||
Unknown interrupt 21 function 99
|
||||
.sp
|
||||
and exit.
