NetWare's default color palettes, which are set for blue and white, affect all NetWare menu utilities run on all monitors connected to color adapters. The default color palettes work with color monitors. However, when a monochrome
monitor is connected to a composite color adapter, the default foreground and background colors appear with the same intensity, rendering the monitor display unreadable.
This problem generally occurs on COMPAQ and AT&T 6300 computers that run monochrome monitors from a composite color adapter.

COLORPAL
The NetWare color palettes are stored in the
IBM$RUN.OVL fIle in the SYS:PUBLIC directory. All menu utilities use the blue and white default color palettes stored in this fIle until either the palettes are changed to black and white or the utility is instructed to search for a different overlay file.
NetWare v2.1 and above includes a new fIle called
CMPQ$RUN.OVL, which contains black and white default color palettes. These defaults should be used by computers that have problems using the blue and white defaults.
If you have a computer (such as an AT&T or COMPAQ) that runs a monochrome monitor from a composite color adapter and menu screen displays appear on your screen with little or no contrast, you can solve the problem by completing one of the following steps:
• Change the short machine type specified in the boot diskette's SHELL.CFG fIle to CMPQ. See the next section.
• Change the prefix of the CMPQ$RUN.OVL fIle to match the short machine type (such as AT&T). See page 111.
• Change the default color palettes to black and white using COLORP AL. See page 113.
Change the short machine type in the SHELL.CFG file
548jRev1.0
If any stations on your network have menu screens that are unreadable, you can solve the problem by changing the short machine type (in a SHELL.CFG fIle on the boot diskette) from "IBM" to "CMPQ" for each computer that exhibits the problem. The computers then access the CMPQ$RUN.OVL fIle (with the black and white color palette defaults) when·
you run NetWare menu utilities.
If you do not have a SHELL.CFG fIle on your boot diskette, you can create one by following the instructions in the Installation for ELS NetWare Level II manual.

COLORPAL
To change the short machine type, complete the following steps.
1. Insert the workstation boot diskette into drive A.
2. Bring up the SHELL.CFG me with a text editor.
3. Erase the existing short machine type (if it is not CMPQ) and type "CMPQ" in its place.
If no short machine type is specified, insert the following line anywhere in the SHELL.CFG me:
SHORT MACHINE TYPE = CMPQ
Rename the NetWare Electronic Mail files
If you change the short machine type of your workstation and you plan to continue using the NetWare Electronic Mail utility, you must copy and rename the Electronic Mail overlay and help meso
To duplicate and rename the mail mes (you need Write and Create rights in SYS:PUBLIC), complete the following steps.
1. Make sure your default drive is mapped to the SYS:PUBLIC directory.
2. Type
NCOPY IBM$EMS.OVL CMPQ$EMS.OVL <Enter>
NCOPY IBM$EMS.HLP CMPQ$EMS.HLP <Enter>
NCOPY IBM$DRV.OVL CMPQ$DRV.OVL <Enter>
The fIles are duplicated with the new names.
Now you have IBM$*.* mail fIles and CMPQ$*.* mail fIles in SYS:PUBLIC. Depending on the short machine type in the SHELL.CFG fIle, each workstation accesses the corresponding default color palettes and mail fIles.

Change the prefix of the CMPQ$RUN.OVL file
548/Rev1.0
You can solve the problem of unreadable menu screens by changing the prefix of the CMPQ$RUN.OVL file to
whatever your short machine type is; for example, you could change the me to AT&T$RUN.OVL (the new prefIx you give the file must match the short machine type in your SHELL.CFG me).
To rename the CMPQ$RUN.OVL me instead of changing the short machine type, complete the following instructions.
At the DOS prompt, type
REN CMPQ$RUN.OVL AT&T$RUN.OVL <Enter>
This example assumes that all workstations on the network use the short machine type AT&T and none use CMPQ.
The defaults saved in the AT&T$RUN.OVL file are now used by all computers whose short machine type is specifted as AT&T.
H you have more than one type of computer with a
monochrome monitor attached to a composite color adapter, you can duplicate and rename the CMPQ$RUN.OVL file so that you have overlay mes for each type of computer on your network.
For example, if you have IBM, COMPAQ, and AT&T computers on your network, you can map your default drive to SYS:PUBLIC and type the following:
NCOPY CMPQ$RUN.OVL AT&T$RUN.OVL <Enter>
(You must have Read, Open, Create, and Delete rights in SYS:PUBLlC.) You now have "IBM," "CMPQ," and
"AT&T" overlay files that are accessed according to the short machine type found in the SHELL.CFG file on the boot diskette of each workstation.

(This example assumes that the short machine type is AT&T.) The files are duplicated with the new names.
If you have specified other short machine types for computers on your network, duplicate and rename the mail files for each short machine type you have specified.
Now you have IBM$*.* mail files and AT&T*.* mail files (or whatever you renamed the mail files to) in
SYS:PUBLIC. Depending on the short machine type in the SHELL.CFG file, each computer accesses the corresponding default color palettes and mail files.

COLORPAL
Change the default color palettes to black and white
Note:
548/ReV1.0
You can use COLORP AL to change your current default color palettes to black and white. With black and white defaults, your menus have the correct contrast and are readable. To change your default color palettes to black and white, complete the following steps.
Use the Escape key at any point in the COLORPAL program to return to the previous menu, or to exit the program altogether.
1. Ensure that your default directory is SYS:PUBLIC and that you have Read, Write, Open, Create, and Delete rights.
2. Enter COLORP AL. The "Defined Palettes" menu is displayed, listing palettes 0 through 4. NetWare menus use these palettes for the following:
3. Select the default palette you want to change. For example, select "Palette 0." The "Edit Attribute" and
"Current Palette" windows appear.
The "Edit Attribute" window displays some of the attributes you can change:
Background Normal
COLORPAL
The color attributes, as they appear in NetWare menus, are as follows:
• "Background Normal" is used for the field on which the menu titles and text are displayed.
• "Foreground Normal" is used for normal text and border displays.
• "Foreground Intense" is used to highlight the text and borders for menu options currently active.
• "Foreground Reverse" is used for text covered by the highlight bar.
• "Background Reverse" is used for the highlight bar.
The "Current Palette" window displays the following:
NormaL Intense Reverse
The three lines in the "Current Palette" window show how the color attributes appear before you make changes.
4. To change these attributes to the correct value of black and white, select the first attribute in the "Edit
Attribute" box. The "Select Color" list appears.
For example, select "Background Normal" to change its color.
Whenever you choose an attribute in the "Edit Attribute"
box, the "Select Color" list appears. This list varies according to whether you are editing the foreground or the background.
