1024x768 70 Hz 75 MHz

1280x1024 66 Hz 119 Mhz

__________________________Note_____________________________

Once the DEC OSF/1 system is powered on, the mach64 runs in VGA text mode

as a terminal device. If a graphics option other that the mach64 (e.g., ZLXp)

was previously running in the system, be advised that X/Motif cannot be started

until the OS kernel has been reconfigured.

____________________________________________________________

With the mach64 installed, the following procedure applies:

1. Reboot using “genvmunix”:

boot -fi “/genvmunix”

2. Log in as a “superuser” with full privileges.

3. Copy the “vmunix” file within root to a backup file:

cp /vmunix /vmunix.sav

4. Run the “doconfig” program from /usr/sbin/ to create a new kernel file. For additional

details on reconfiguring the kernel, please refer to the Guide to System Administration

(#AAPS2RA-TE).

5. Move the new “vmunix” kernel file (location reported during doconfig) to “vmunix”.

This will overwrite the old kernel file.

mv /sys/<SYSTEM_NAME>/vmunix /vmunix

6. Perform a shutdown with automatic reboot:

shutdown -r now

7. Upon rebooting, the operating system automatically detects the presence of the

mach64 and defaults to the 1024 x 768 display resolution mode.

Changing OSF/1 Display Characteristics

To change to any one of the other supported resolution and refresh modes, continue with

the following steps:

1. Change directory to /var/X11/xdm. Execute the command:

chmod +x Xservers

2. Edit the “Xservers” file.

vi Xservers

3. At the end of the line that reads “:0 local /usr/bin/X11/X -nice -2 ...”, remove any

parameters appearing after the “-2” and append one of the following declarations:

-screen0 640, or

-screen0 800, or

-screen0 1024, or * default setting

-screen0 1280

Example: :0 local /usr/bin/X11/X -nice -2 -screen0 1280

4. When editing is complete, save and perform a shutdown with automatic reboot for

changes to take effect:

shutdown -r now
