The SuperCPU was designed with GEOS users in mind. In fact, the SuperCPU
has a special optimization mode supplied intentionally to help speed GEOS
operations. Before using GEOS with the SuperCPU, however, users need to
run the GEOS SuperInstall program supplied with the unit. SuperInstall automatically
installs options on your GEOS boot disk that are necessary to use the SuperCPU
with GEOS. The additions and modifications made by SuperInstaller are as
Complete step-by-step instructions for using SuperInstall to modify GEOS
boot disks are included in the SuperCPU Users Guide. Once the patches and
additional files have been installed, you'll be able to boot GEOS in the
same manner in which you have always done. In addition, your GEOS boot disk
will continue to function properly whether the SuperCPU is present or not
-- the new routines automatically detect your hardware configuration while
- Modifies your 'GEOS' boot file so that it will force the SuperCPU
to 1 MHz while the initial load is taking place
- Creates the SUPERGEOS auto-exec file which installs the SuperCPU GEOS
Kernal patches during booting
- Determines if you're using a CMD SmartMouse, and creates the SuperSmart
driver if you are. If you're using some other mouse, SuperInstall will instead
default to the option that creates a Super1351 mouse driver. If you have
only a joystick, no driver will be selected.
SUPERGEOS AS AN APPLICATION
While SUPERGEOS functions mainly as an auto-exec that installs SuperCPU
patches during the boot process, it can also be run as an application. When
operated in this manner, it presents a representation of the SuperCPU front
panel controls, but with one additional switch on the far right, labelled
'GEOS OPTIMIZE'. While the UNIT and JIFFYDOS switches shown on the displayed
control panel do nothing, clicking on SPEED or GEOS OPTIMIZE switches changes
these functions within the SuperCPU itself (as well as on the screen). This
control panel can thus be used to change the speed of your SuperCPU, or
to disable the GEOS Optimization mode which is normally turned on during
the boot process.
SUPER MOUSE DRIVERS
The two Super mouse drivers have been specially designed to make mouse input
devices operate smoothly at high speed. To facilitate this, one of the mouse
buttons has been programmed to switch TURBO mode off while the button is
held down. The following shows the button assignments for the two drivers:
- SuperSmart Driver
- Left Button: Turbo Single-click
- Center Button: Normal Single-click
- Right Button: Turbo Double-click
- Super1351 Driver
- Left Button: Turbo Single-click
- Right Button: Normal Single-click
ADDITIONAL NOTES ON GEOS
Due to the use of the GEOS Optimization mode built into the SuperCPU, GEOS
applications are able to operate at a highly efficient speed. In addition,
thanks to the expertise of GEOS programmer Maurice Randall, the provided
GEOS patches deliver an extremely high level of compatibility. GEOS programmers,
however, just like many other Commodore programmers, don't always follow
conventional standards -- even Geoworks' (formerly Berkeley SoftWorks) programmers
would occasionally throw caution to the wind and break some of their own
guidelines in writing GEOS applications. While every attempt has been made
to assure that things will work smoothly, there are bound to be some oddities
lurking about. The SuperCPU enables GEOS to run at speeds many times faster
than the original authors could have ever foreseen possible. While we can't
guarantee every problem can be resolved, we will investigate and attempt
to duplicate and resolve all problems which are reported and properly documented.
That aside, the following are a few notes about various GEOS attributes
with respect to the SuperCPU and SUPERGEOS patches:
- After installing the GEOS patches on your boot disk, it can still
be used to boot your system without a SuperCPU as well as with one.
- The GEOS patches can be applied to GEOS boot partitions on CMD devices
that were created with geoMakeBoot.
- For guaranteed results, the GEOS patches should only be applied to
original GEOS boot disks and disks or partitions created with geoMakeBoot.
Other boot disk creation methods may be compatible, but we cannot guarantee
- You shouldn't create geoMakeBoot disks after booting from a patched
disk. Boot with a stock GEOS disk, create a geoMakeBoot boot disk, and then
apply the patches to the newly created boot disk.
- SUPERGEOS should always appear on your boot disk before Configure,
especially if you use a RAM device with the RAM Reboot option selected.
- A portion of the GEOS patches reside in the SuperCPU itself, in a
new RAM area reserved for system use. If a program happens to trash that
area -- however unlikely this is -- you may experience problems performing
a RAM reboot (RBOOT) using power- or battery­p;backed RAM devices. The
odds of this happening are slim, but it's possible.
- To avoid areas that other programmers might use within applications,
the GEOS Kernal routine 'ToBASIC' has been patched and partially relocated
into the SuperCPU. We don't expect this to create any compatibility problems,
but programmers may want to be aware of this.
- The GEOS patches applied to the 'ToBASIC' routine also make GEOS perform
a better reset. This means that all JiffyDOS commands work correctly now
when exiting from GEOS. Programs such as 'CleanReset 64' are no longer required.
