Follow these steps when installing ISA cards: 1. Remove all PnP cards installed in the system, if any. 2. Install non-PnP ISA cards. 3. Turn on the system. 4. Use Windows 95 or ICU to manually assign the appropriate IRQs to the cards. This ensures that BIOS will not use the resources assigned to the non-PnP ISA cards. BIOS detects and configures only PnP cards. 6. Turn off the system. 7. Locate the expansion slots and install the PnP ISA and PCI cards. 8. Turn on the system. This time PnP BIOS automatically configures the PnP ISA and PCI cards with the available resources. Chapter 4 - Installing Optional Components 4-7 4.4 Installing Additional Memory The system memory is upgradable to a maximum of 256 MB via two 168-pin DIMM sockets on board. These DIMM sockets accept DRAMs with 8-, 16-, 32-, 64-, and 128-MB capacities, 60 ns (nanoseconds) or less access time, and with ECC. See Figure 2-1 for the location of the DIMM sockets. Section 4.4.1 tells how to install DIMMs. Table 4-1 lists possible memory configurations. 4-8 AcerPower 6000 User’s Guide Table 4-1 Memory Configurations Table 4-1 Memory Configurations DIMM2 Total Memory 8 MB 8 MB 16 MB 16 MB 32 MB 32 MB 64 MB 64 MB 128 MB 128 MB 8 MB 8 MB 16 MB 16 MB 32 MB 32 MB 64 MB 64 MB 128 MB 128 MB 8 MB 16 MB 24 MB 16 MB 32 MB 48 MB 32 MB 64 MB 96 MB 64 MB 128 MB 192 MB 8 MB 8 MB 16 MB 16 MB 16 MB 32 MB 32 MB 32 MB 64 MB 64 MB 64 MB 128 MB 128 MB 128 MB 256 MB Chapter 4 - Installing Optional Components 4-9 4.4.1 4.4.1 1. Open the clips on the socket. 2. Align the DIMM with the socket. 3. Press the DIMM into the socket until the clips lock into the DIMM. Figure 4-7 Installing a DIMM The DIMM socket is slotted to ensure proper installation. If you insert a DIMM but it does not fit easily into the socket, you may have inserted it incorrectly. Turn the DIMM around and try to insert it again. 4-10 AcerPower 6000 User’s Guide 4.4.2 4.4.2 1. Press the holding clips on both sides of the socket outward to release the DIMM. 2. Gently pull the DIMM out of the socket. Figure 4-8 Removing a DIMM 4.4.3 Reconfiguring the System The system automatically detects the amount of memory installed. Run Setup to view the new value for total system memory and make a note of it. Chapter 4 - Installing Optional Components 4-11 4.5 4.5 The board supports a Pentium II processor or a Celeron processor. Both processors come in a new enclosed packaging technology called S.E.C. (Single-Edge Contact) cartridge. The only difference between the two is that the Pentium II processor comes with 256-KB or 512-KB built-in second-level cache, while the Celeron processor comes only with an internal cache. Both are capable of increasing the performance of 32-bit software and multimedia applications. 4.5.1 Removing the Processor Card Observe the ESD precautions when installing or removing a system component. See section 4.1.1. Before you can replace or upgrade your processor, you need to remove the previously installed processor on the system board. Follow these steps to remove the processor card: 1. Press the latches on both sides of the processor to release it from the retention mechanism. You will hear a click sound once the latch is released. Figure 4-9 Pressing the Latches 4-12 AcerPower 6000 User’s Guide Chapter 4 - Installing Optional Components 4-13 2. Pull the processor to totally detach it from the CPU connector. Figure 4-10 Removing a Processor Card 4.5.2 Installing a Processor Card Observe the ESD precautions when installing or removing a system component. See section 4.1.1 Before you proceed, make sure that there is no processor installed in the CPU connector. Follow these steps to install a processor card: 1. Place the retention mechanism over the CPU connector on the system board and press it until it clicks into place. 2. 2. Figure 4-11 Installing the Retention Mechanism 3. Remove the processor card from its protective packaging. Make sure that the latches on the sides of the module are not pressed. 4. Remove the thermal tape protector at the back of the fan sink. Figure 4-12 Removing the Tape Protector from the Fan Sink 5. Insert the wide clip ends into the wide holes on the processor and the narrow clip ends into the narrow holes. 4-14 AcerPower 6000 User’s Guide Chapter 4 - Installing Optional Components 4-15 Figure 4-13 Inserting the Clip Ends into the Processor Holes 6. Using your fingers, push down the metal bracket until it clicks into the CPU cartridge and then push the metal bracket’s handle to lock the metal bracket into place. Figure 4-14 Locking the Metal Bracket 7. With the processor card golden fingers pointing downward, align the processor to the posts of the retention mechanism. 8. Lower the processor into to the CPU connector on the system board until the golden fingers touch the connector. 4-16 AcerPower 6000 User’s Guide Figure 4-15 Installing a Processor Card 9. Press down the processor until the golden fingers completely fit into the connector and the latches on the ...
