If the user presses the power button on the control panel, HP Off (under
Windows 95) first checks if there are any unsaved files. If there are, it offers
three choices: yes (to saving the unsaved changes, followed by shutdown),
no (to saving the unsaved changes, but shutdown anyway), and cancel (to
return to normal operation).

NOTE Anticipate the customer’s upgrade needs.
With memory banks A, B and C filled,
no ISA board fits in the lowermost
slot (unless it is less than 9 cm wide,
3.6 inches).
With memory banks A and B filled,
only XT boards fit in the lowermost
ISA slot (10.7 cm wide, 4.2 inches). XT
With only memory bank A filled, any
ISA board will fit in the lowermost
slot: AT boards (12.2 cm wide, 4.8

New Architecture: UMA / SFB
New Architecture: UMA / SFB
Key Points • DRAM is shared between Video RAM and System RAM.
• There is no dedicated video RAM on the system board.
• A portion of the main memory is used as frame buffer (video memory). It
is non-trivial to determine exactly into which physical memory chips the
BIOS will place the video memory (that is, where it will be position in the
memory map).
• The size of the video memory is configured by software only. There
is no specific video memory upgrade to add.
• Increasing the amount of video memory causes the amount of main
memory available for system use to be reduced:
• The default setting is for 1 MB video memory. This can be increased to
2MB.
• If an external video board is present, with its own video memory, the full
amount of main memory is allocated for use as system memory.
Configuring the Video Memory Size
Windows 95 only The following illustration depicts the control display that allows the amount
of video memory to be changed.
1In the “Control Panel”
2Select “Display”
3Select “HP Dynamic Video”
The HP Vectra VE 5/xxx series 3 PC does not have dedicated video
memory. It has a Unified Memory Architecture (UMA) and uses a Shared
Frame Buffer (SFB). The SiS 6205 video controller uses a reserved portion
of the main memory.
SystemMemory = MainMemory - VideoMemory

New Architecture: UMA / SFB
The amount of system memory resizes automatically as the amount of video
memory is changed. (Conversely, the amount of video memory resizes
automatically if the control for the amount of system memory is changed).
OtherOperatingSystems
(though also valid for
Windows 95)
For other operating systems, configure the video memory size in the Setup
program.
1Restart the PC, and type to run the Setup program.
2Select the “Configuration” screen.
3Select the “Video” sub-menu.
4Select the desired setting in the “Video Memory Size” field.

Replacing the System Board
Replacing the System Board
Enter the PC product type whenthe HP
product utility is running
Enter the PC serial number when the
HP serial number utility is running
Flash the latest BIOS
Install main memory modules
Clear the product indentifier:
Switch off the PC; remove the J15
jumper from the system board; restart
the PC; turn off the PC; re-install the
J15 jumper; restart the PC
If the wrong product type is indicated
OK
Do not remove the thermal interface
material between the processor and
the heat-sink. To do so would affect
the cooling of the processor.
Always flash the latest version of the
System BIOS. You may have been
provided with a system board with an
old version of the BIOS.
• Download the latest BIOS file from
the HP World Wide Web Site:
http://www.hp.com/go/vectrasupport
• Follow the instructions given in the
downloaded Read.Me file.
Do not reinstall the memory modules
haphazardly. (See next page for
description).
After replacing the system board,
re-install processor, cables, etc.

2 Product-Specific Tasks
Installing Main Memory Modules
Installing Main Memory Modules
• The three memory banks must be filled in the order A, B, C.
• Always install a pair of identical modules in bank A. In banks B and C, you
may install a single module or a pair of identical modules.
• Fill as few memory slots as possible, by using high capacity memory mod-
ules, to enable better use of the lowermost ISA backplane slot.
Configuration Consequences Rather do
Installing a single module in A1, leaving A2
empty, allows only 32-bit access, and leads
to very poor performance.
Installing a pair of identical modules in A1
and A2 allows 64-bit access.

Installing a single module in B1, leaving B2

identical pair of modules is allowed.
Bank A is accessed in 64-bit widths, whilst
bank B is accessed in 32-bit widths.

Filling all banks prevents the use of the
lowest ISA slot.
This restriction can be avoided by replacing
the four modules of banks B and C by a pair
of modules in bank B of greater capacity.

Installing Main Memory Modules
The PC will fail to function correctly.
When filled in pairs, banks must be filled by
pairs of identical modules: identical in
capacity (in MB); identical in access time;
identical in chip type (EDO); identical in
module type (SIMM).

A Final Test
Draw a Circle Around Each Correct Answer
Draw a Circle Around Each Correct Answer
1The following PC, supplied with a 1.2 GB hard disk, has been upgraded by
the user, but now no longer works. Which of the following could be the
source of its failure to operate properly?
aIt has been fitted with a P54C (VRE) Pentium processor.
bThere is an 8 MB EDO memory module in memory socket A1, and an
8 MB FPM module in A2.
cThere is a 16 MB EDO memory module in memory socket C1, but
socket C2 is empty.
dMemory sockets B1 and B2 are empty (even though there is memory
in bank C).
eA 850 MB IDE hard disk drive has been fitted in the lowest front-access
shelf, and has been connected to the spare IDE socket.
fA network board has been installed in a PCI slot.
2On a PC that is running the Windows 95 operating system, how do you in-
crease the video memory from the default setting of 1 MB to 2 MB?
aInstall two 512 KB video memory chips.
bCall up the Display Properties window.
cRestart the PC, and press to go into the Setup program.
3The user has installed a PCI board in the lowermost PCI slot, a full length
XT board in the lowermost ISA slot, and a half length AT board in the ISA
slot above it. The user has expressed problems installing cache memory
and extra main memory modules. What do you advise?
aMove the AT board to a higher ISA slot.
bMove the XT board to a higher ISA slot.
cMove the PCI board to a higher PCI slot.
dNot to install extra main memory modules, but to replace the existing
ones with modules of higher memory capacity.

1What could be the source of its failure to operate properly?
a It has been fitted with a P54C (VRE) Pentium processor.
b There is an 8 MB EDO memory module in memory socket A1, and an
8 MB FPM module in A2.
d Memory sockets B1 and B2 are empty (even though there is a 16 MB
module in C1).
The HP Vectra VE 5/xxx PC does not support VRE Pentium processors
(166, 200 MHz and the earlier version of the 120 MHz processor), but
only VCC Pentium processors (including the later version of the 120 MHz
processor).
2How do you increase the video memory from the default 1 MB to 2 MB?
b Call up the Display Properties window.
c Restart the PC, and press to go into the Setup program.
Response (b) is the easiest, but response (c) is not wrong (and would
have been the only valid response if the operating system had been
Windows for Workgroups 3.11).
3The user has expressed problems installing cache memory and extra main
memory modules. What do you advise?
b Move the XT board to a higher ISA slot (the combination slot).
c Move the PCI board to a higher PCI slot (the dedicated PCI slot).
Response (a) can also be added to the above two responses (moving
each board up by one slot).
