The video memory is limited to 4 MB on the system board and cannot be upgraded.
Accessory Board Guidelines
The system board in the HP Server tc2100 provides up to five 32-bit PCI slots (P1 through P5).
Tested PCI Boards
For a list of tested PCI boards, check for compatibility under the Hardware Tested Products list for the HP
Server tc2100 under the Technical Support topic for the specific NOS used in the Server at HP’s web site:
http://Server.hp.com/Server/support/compatibility/compatibility.asp
CAUTION Some accessory board outputs may exceed U.S. National Electrical code (NFPA 70)
Class 2 or limited power source limits and must use appropriate inter-connecting cabling
in accordance with the National Electrical Code. (All HP boards comply with Class 2.)
IRQ Settings
The IRQ settings are automatically assigned and do not require user intervention. The HP Server uses the
Plug-and-Play feature of the PCI boards to correctly assign the resources automatically.
Processor Guidelines
This HP Server supports the Celeron and Pentium III processors and each one should have its own heatsink
and cooling fan.
CAUTION If good contact is not made between the processor and the thermal patch on the heatsink,
the processor will overheat and possible damage may occur.
• Ensure you open the ZIF lever before removing or installing the processor into the socket.
The processor socket uses a ZIF (Zero Insertion Force) lever to secure the processor in the socket.
• The ZIF lever should make a clicking sound when it closes completely.
• Ensure you align Pin-1 of the processor with Pin-1 of the processor socket when installing the
processor, or processor pins will be damaged.
• Each processor requires a heatsink with a cooling fan attached.
The Celeron processors use a slightly different heatsink with a smaller cooling fan than the Pentium III
heatsink-cooling fan assembly.
CAUTION To prevent damage to the thermal patch, do not slide the heatsink around on the
processor once it is in place. Rocking it slightly to one side or the other to install both
latches is acceptable.
• Each heatsink should have an undamaged thermal patch on the bottom of the heatsink.
The thermal patch provides the thermal bonding between the processor and the heatsink.
• The plastic sheet/tab on the thermal patch must be removed before placing the heatsink on the processor.
Some thermal patches come with a small plastic sheet (with a finger tab) covering the non-adhesive side
of the patch to help protect the thermal material.
