Running the AST 5251/11 (Regular or Enhanced) emulation package

this particular problem:

|
||
1. Execute the CFG5251.EXE program.

||
|
||
2. Select EDIT and press ENTER.
|
||
|
||
3. Select Y (yes) to modify the file AST5251.CFG and press
|
||
ENTER. If user has created a file with a different
|
||
name, then select N (no) and specify user created file
|
||
name.
|
||
|
||
4. A menu with HARDWARE, KEYBOARD, STATION, SECURITY,
|
||
VDISK, CUSTOMIZE, AND QUIT will appear.
|
||
|
||
5. Press ENTER to select HARDWARE.
|
||
|
||
6. Use the cursor arrow keys to select DSP ADAPTER and
|
||
press ENTER.
|
||

|
||
STARTUP, SNAPSHOT, and QUIT as options.
|
||
|
||

|
||
|
||

|
||
|
||
10. Select COMPOSITE and press ENTER.
|
||
|
||
11. Select NO SNOW and press ENTER.
|
||
|
||
12. Hit ESC twice then select ATTRIBUTES and press ENTER.
|
||
|
||
13. Now the options will be NORMAL, REVERSE, and QUIT.
|
||
|
||
14. Hit the ENTER key to select NORMAL.
|
||
|
||
15. Enter the values that are stated on the next page value
|
||
for value.
|

|
||
|
||

|
||
and press ENTER.
|
||
