Notes on TwinTurbo™ Control Panel:
This Control Panel requires the new Display Library which is part
of System 7.5.3 and is a separate file on older system. If you
encounter the problem of the board not preserving the resolution
after reboot you may want to upgrade your system to 7.5.3. This can
be done by installing the new system or by upgrading 7.5 with System
Enabler 2.0.

1. This upgrade applies to Twin Turbo™ 128M and Twin Turbo™
   128M2 boards only.
2. This version fixes the bug that causes LocalTalk to freeze when
    copying large files.
3. If you have version 2.1 ROM or less with this upgrade, you would be
    able to access all the resolutions the board supports, up to
    1920x1080. Just plug the monitor into the VGA connector and
    leave the Mac connector open. It should come up with default
    resolution or the resolution from last boot. The default resolution
    is 640x480x60Hz for version 2.1 or 2.0 ROM and 832x624x75Hz for
    version 1.x ROM plus the upgrade.

To force the system to the default resolution, follow the following procedure:
- Reboot and hold down command-option-p-r.
- Wait till the system restarts. Release the keys and hold down shift
   key.
- Release the key after the "Welcome to Macintosh. Extensions Off."
   message shows up.
- The system should be in default mode.


Notes on TwinTurbo™ 128M8:
- The resolution 1920x1080 Millions mode is not supported at 72Hz.
- It is recommended that the system has at least 32M of memory
   installed for maximum performance.
