SUMMARY

This article covers the steps required to install and configure Microsoft DOS on a Windows NT 4.0 Remoteboot server. This article assumes you are using MS-DOS version 6.22 in all examples.

MORE INFORMATION

Installing DOS

Verify that the Winnt\Rpl\Rplfiles directory is being shared on the remoteboot server with a share name of Rplfiles. If your system does not have this share, then you either have not installed remoteboot properly or have stopped sharing this directory. To resolve this problem, stop and restart the Remoteboot Server service. After the service has restarted, the Rplfiles share should be recreated. If the share fails to create, your remoteboot service is not operating properly, and you must remove and reinstall the Remoteboot service.
From an MS-DOS client (running the version of MS-DOS you want to support on the Remoteboot server), log on to the network as Administrator and connect to the Remoteboot server's Rplfiles share by typing:

net use M: \\NTSERVER\RPLFILES

where NTSERVER is the name of the Remoteboot server.
Copy all the MS-DOS files to the M:\Binfiles\Dosxxx directory by typing the following commands. You will need to replace the xxx with the appropriate DOS version (eg. DOS622 for DOS version 6.22).

COPY C:\DOS\*.* M:\BINFILES\DOS622
ATTRIB -S -H C:\IO.SYS
COPY C:\IO.SYS M:\BINFILES\DOS622
ATTRIB +S +H C:\IO.SYS
ATTRIB -S - H C:\MSDOS.SYS
COPY C:\MSDOS.SYS M:\BINFILES\DOS622
ATTRIB +S +H C:\MSDOS.SYS

The files Msdos.sys and Io.sys must have the hidden and system attributes removed prior to copying them to the server. Once the copy has been completed, remember to reset the hidden and system attributes on the client computer (not on the Remoteboot server) for the DOS system to boot properly.

NOTE: The hidden and system attributes should not be set on the Remoteboot server. If these attributes are set, then the DOS Remoteboot client will not boot properly and will display an error:
Non-System Disk error or disk error
If you copied DOS files other than MS-DOS, you must rename the input/output system file to Io.sys and the Disk Operating System to Msdos.sys. The following example is based on IBM's PC-DOS.

Rename Ibmdos.com Msdos.sys
Rename Ibmbio.com Io.sys

Please note that the remoteboot service is designed to support Microsoft DOS.

Activating the DOS Version

From the Windows NT remoteboot server, start the Remoteboot Manager.
Select Configure from the menu bar, and then click Check Configurations. This will check the remoteboot system for all available operating systems and make them available for the clients.

Creating a Remoteboot DOS Client Profile

From the Windows NT Remoteboot server, start Remoteboot Manager.
Select Remoteboot from the menu bar, and then click New Profile.
When the New Profile dialog box appears:

Type a Profile Name: MSDOS622

Select the Configuration: DOS 6.22 3Com Etherlink II

For the Description: Type any descriptive comments

NOTE: Any comments typed prior to selecting a configuration or changing a configuration will be over-written with default comments.
Click OK to save the new profile.

Assigning a Profile to a Remoteboot Client

Connect the Remoteboot client to the network, and power the system on. The client should start searching for the Remoteboot server. The retries counter should increase at a steady pace.

NOTE: If your remoteboot client has a hard disk drive and the network interface card's Remoteboot PROM does not take control of the boot process, please see the following article in the Microsoft Knowledge Base:

TITLE : How to Enable Remoteboot on a Client's Hard Disk
From the Windows NT Remoteboot server, start Remoteboot Manager.
Select the workstation name corresponding to the client's media access control address. The client will have registered its address automatically with the server.

The media access controll address is a unique 12-digit hexadecimal number supplied by network adapter firmware. This ID identifies the adapter type and manufacturer using the first six digits. If this number is not displayed in Remoteboot Manager, press the F5 key. If you still do not see this number, it is possible that you have not installed Remoteboot Manager properly, that the DLC protocol is not installed, or that your client and server are separated by a router that is not forwarding DLC packets.
Select Remoteboot from the menu bar, and then click Convert Adapters.
When the Convert Adapters dialog box appears:
- Type a workstation name for the client.
- Type a detail description for the client computer.
- Type a password if desired. A blank or Null password allows the Remoteboot client to connect to the RPL server without any operator intervention after the power is turned on.
- Select the Configuration type:
  Shared: the client can share its profile with other clients
  Personal: the must have it own unique profile
- Select the desired Workstation Profile
- Select TCP/IP DHCP / TCP/IP SETTINGS. If you select TCP/IP settings, consult your network administrator for proper configuration.
  
  NOTE: If you are not using TCP/IP, then select the TCP/IP DHCP option.
Click ADD. The Remoteboot system will then create a user account for the computer, and the Remoteboot client will continue the startup process using the assigned profile.

This completes the installation of MS-DOS on a Remoteboot client.
