Chapter 4 - PowerPack: PowerControl Software
When you are done with the tests, click “Done With Tests” to
return to the main PowerControl screen.
SCSI Devices
This window allows you to display the devices on the internal
and external SCSI chains, as well as any devices connected to
PCI SCSI cards. A pop-up menu displays the SCSI bus being
scanned:
The SCSI Bus pop-up menu allows you to select among inter-
nal, external or add-in PCI SCSI busses. You can force the
bus to be scanned again by pressing the Update button. You
can also use the Mount button to mount the selected device.
At the bottom of the window the block size, number of
blocks, and total capacity of the selected device is displayed.
Note that IDE devices used on newer PowerMacs are not
recognized.
PCI Cards
This window, similar to the SCSI Devices window shown
above, displays the slot number, type, manufacturer and revi-
sion level of all PCI cards installed in your machine.
A panel at the bottom of the window displays the manufac-
turer's name and the card name in more detail when possi-
ble. The slot number matches the ones adjacent to the PCI
slots on the motherboard.
Chapter 4 - PowerPack: PowerControl Software
In the example above, there are four DIMMs installed. Two
of the DIMMs are in corresponding slots, A3 and B3. They
are the same size (8 MB each) and are therefore being inter-
leaved. The other two, although the same size (32 MB each)
are not in corresponding slots – they are in slot A4 and B5.
The “Move To” column indicates the DIMM in slot B5 should
be moved to slot B4. This will then enable the two 32 MB
DIMMs to be interleaved, thus improving the performance of
that 64 MB of memory.
For more information about memory, you can choose the
“PowerControl Report” item from the “Windows” menu. This
report is discussed in detail below.
Tests
Clicking this button changes the options available in the
main PowerControl window:
Three tests are available: Processor Test, SCSI Test, and
Memory Test.
When you click in any of the test buttons a series of tests for
the specified subsystem will automatically be performed. Yo u
will be informed of any problems if they are encountered. At
the end of the tests a final report will be presented after which
you may return to the test selection window shown above.
For more information about the individual tests see the
“Launch Menu” description in the PowerControl menus sec-
tion below.
