Q: How can I boot my Radius 81/110 system if I can't start from
the CDRom?
A: Download the RadiusRescue
disk image and create a bootable disk for the Radius 81/110. You
will need
DiskCopy , Mount Image, ShrinkWrap, or similar program to make a
boot disk from the disk image. DiskCopy 4.2 is on the Radius System
CD.
Q: Is the Radius 81/110 system compatible with System 7.5.3 and
higher?
A: Yes, the Radius 81/110 system is compatible with System 7.5.3 and
higher. We recommend doing a clean system install from the Radius CD
for 7.5.1, then run the Apple 2.0 updater for 7.5.3 to get to the new
7.5.3 operating system. To do a clean system install, launch the
7.5.1 installer, and on the 'install' screen, press down
COMMAND-SHIFT-K to get the 'install new system ' option. Clicking on
this option will allow you to do a 'clean' system' install. Be sure
to copy the control panel CD-ROM Toolkit included with the 81/110
into your new control panels folder.
Note that when installing OS 8, you will be prompted to update the
low level drivers. For the 81/110, this is unecessary. The 81/110
uses an FWB driver, and FWB reports no OS 8 incompatibilities with
any versions of their drivers.
Q: Can I remove the cover on the Radius 81/110 and install
additional equipment without voiding my warranty?
A: Yes. Removal of the cover for installation of additional cards or
hard disk drives does not void your warranty.
Q: I installed Apple's VRAM or AV video board in the Radius 81/110
with a second monitor, and now I do not have the Menu Bar on the
proper monitor.
A: Use the Monitors control panel to choose which monitor has the
Menu Bar. While the Monitors control panel is open, drag the menu bar
from the icon of one monitor directly to the icon of the monitor on
which you want the menu bar to appear. You can also change the
start-up monitor from within the Monitors control panel by holding
down the option key on your keyboard. Drag the small "happy Mac" icon
that appears on the icon of the current start-up monitor to the icon
of the monitor you want to use as the start-up monitor.
Q: How do I reformat the internal hard disk drive?
A: You'll find the Apple HD SC Setup utility on the Radius 81/110
CD-ROM. This utility is used to repartition and reformat the hard
disk drive. Please follow the instruction manual for use of this
utility.
Q: What is the SCSI ID number of the internal hard disk
drive?
A: The internal hard disk drive is ID 0 on SCSI bus 0.
Q: When I insert a CD ROM, the system will not recognize it.
A: The CD-ROM drive requires the CD-ROM ToolKit™ control panel
from FWB. Install the CD-ROM ToolKit™ control panel into the
Control Panels folder and then restart the 81/110. If the CD-ROM
ToolKit™ control panel is not found on the hard drive, the
Radius 81/110 must be started from the Radius System CD-ROM that was
supplied with the 81/110. To boot from this CD-ROM, insert it into
the CD-ROM drive and hold down the command-option-shift-delete keys
while restarting. The 81/110 will now start from the CD-ROM so that
you may copy the CD-ROM ToolKit™ control panel to your hard disk
drive.
The CD-ROM ToolKit™ control panel can be found on the Radius
81/110 CD-ROM within the Other Installers & Software folder in
the Radius Extras folder within the CD-ROM ToolKit™ folder.
Q: What is the small card installed in the slot next to the NuBus
slots?
A: That is the PDS terminator. It is required to terminate the NuBus
slots. Cards installed in the 81/110 may not operate correctly if
this terminator is removed and no suitable alternative, such as an
Apple AV card or HPV (or VRAM expansion) card, is installed in its
place.
Q: Can I replace the PDS terminator with Apple's VRAM or AV board
for the Power Macintosh 8100?
A: Yes. The Apple VRAM and AV boards work in the Radius 81/110 . The
PDS slot must always have a VRAM, AV board, or PDS terminator
installed.
Q: Something happened to my hard drive and I can't boot my Radius
81/110. What should I do?
A: If you can't boot from the hard drive, you may boot from the
CD-ROM supplied with your Radius 81/110. Insert the CD-ROM into the
CD-ROM drive and start the Radius 81/110 while holding down the
command, option, shift, and delete keys. The Radius 81/110 will
bypass the internal hard disk drive and start from the CD-ROM.
If necessary, you may now reinstall the operating system on your
internal hard drive from the CD-ROM.
Q: How do I remove the front cover on the Radius 81/110 to get to
the internal drive bays?
A: The front cover is press-fit onto the Radius 81/110. There are
three steps to removing the front cover.
First: Remove the side panel by removing the three screws along
the rear right edge of the Radius 81/110. The side panel will now
slide back and can be removed.
Second: Look for a small, square notch, inside the case and next
to the CD-ROM drive bay. Insert a small, flat-blade screwdriver into
this notch, and lever the front cover forward and away from the
Radius 81/110 case.
Third: Allow the cover to drop down slightly to free it from hooks
on the bottom of the inner front panel, which hold the front cover in
place. Elevate the front of the Radius 81/110 about 1/2” to
allow downward movement of the front cover. Slide the front cover
down and then forward to remove.
With the front cover removed, the internal drive bays are now
accessible.
