Overview
HP Vectra 500 Series PCs are Pentium-processor, ISA/PCI-based PCs,
housed in desktop and minitower casings. The series is targeted at the Small
Business Small Office (SBSO) market.
System Board
There are three system board options for models 520 and 525. The three
options can be referred to as Type A, Type B and Type C.
Type A (part number D4051-63001) is a new system board which
incorporates a technology known as Unified Memory Architecture (UMA).
Using UMA, there is no dedicated video memory. Instead, a portion (1 MB or
2 MB) of main memory is shared as video memory. Refer to Chapter 2 for
more information about this system board.
Type B (part number D3657-63001) is the same as the system board used in
the Q1 1996 collection (models 510 and 515).
Type C (part number D3661-63001) is used for one product only. This board
is the same as the Type B board but without the onboard video controller
and memory. Video control and memory is obtained using a Matrox MGA
Millennium video card.
Backplane
There are two backplane options for models 520 and 525—one for the
desktop and one for the minitower. The two backplanes are the same as
those used in the Q1 1996 collection (models 510 and 515).
Case
There are two casing options for models 520 and 525—one for the desktop
and one for the minitower. The two backplanes are the same as those used
in the Q1 1996 collection (models 510 and 515).
Air Flow Guide
With high speed processors (166 MHz and above), an air flow guide is
required to help the fan dissipate the heat from the processor. On desktop
models, a special power supply unit integrates the fan over the processor.

System Board Switches and Jumpers
This section indicates the switches and jumpers used to modify the system
settings.
SW1 Switch
This switch is multi-purpose and is used to modify BIOS, CMOS and
password settings.
SW2 Switch
This switch is used to select the CPU Bus Frequency / CPU Frequency ratio.
The following table includes some examples of the settings to use for
different processor speeds. (Jumper J7 settings are also shown. This jumper
is described on the next page.)
Switch Default
Setting OFF ON COMMENTS
1 OFF Flashing Enable Flashing Disable Updating the BIOS. Set the security mode. Set the switch to the ON
position to prevent the BIOS from being upgraded.
2 OFF CMOS is in normal
operation
CMOS Clear To clear the CMOS configuration. Set the switch to the ON position and
restart the PC. Return the switch to the OFF position and restart the PC
to return to normal operation.
3 OFF Password is in normal

Password Clear To clear the password. Set the switch to the ON position and restart the
PC. Return the switch to the OFF position and restart the PC to return to
normal operation.

CPU Bus Frequency Jumper (J7)
This jumper sets the CPU bus frequency. The following figure shows the
possible settings.
Cache Jumper (J6)
This jumper selects the cache type—either synchronous or asynchronous.
The default setting is for synchronous cache. The following figure shows the
two settings.
Space-bar Power-on Feature Jumper (JP4)
The Space-bar Power-On feature (“KBD Start” on the system board) enables
the PC to be turned on using the spacebar. To enable this feature, a jumper
has to be inserted. This setting overrides the setting in the Setup program.

Video Options
With models 520 and 525 there are three video options:
•Video controller and video memory on the system board.
•Video controller and video memory on a video card.
•Video controller on the system board and video memory that is shared
main memory.
Video Controller and Video Memory on the System Board
This option is the same as the video option in the Q1 1996 collection
(models 510 and 515). That is, 1 MB of video memory as standard on the
system board which can be upgraded to 2 MB by installing two memory
chips of 512 KB each.

Shared Main Memory
Some PCs have a video system that uses Unified Memory Architecture
(UMA). What this means is that the video controller does not use dedicated
video memory, but instead uses a portion of main memory as video memory.
The amount of “shared” memory can be set to either 1 MB or 2 MB. To do
this, use either the Video Memory Size item in the Setup program, or the
HP Dynamic Video Feature which is accessible via the Windows 95 Control
Panel.
The following video resolutions are typically available.

Aztech AT3300 Connections
The Aztech AT3300 audio fax/data modem incorporates built-in advanced
communication and audio telephony features, including the capability to
perform simultaneous audio playback and recording, as well as hands-free
communication.
CAUTION: To ensure that the telephony features of the Aztech card function correctly
a special phone cable is required. Using standard phone cables will result in
a loss of functionality.
Telephone Connections for the U.S., Canada and Spain
The Aztech AT3300 audio fax/data modem only has one external connection
so a splitter cable (delivered with the PC) is required to connect the
telephone line and handset. The connections are shown below.
