Memory
The system memory is upgradable to a maximum of 256MB via two 168-pin DIMM sockets on board. These DIMM sockets accept 8-, 16-, 32-, 64-, and 128-MB standard DRAMs with Parity Check or Error Correction Code (ECC) feature at the 66MHz bus speed and 16-, 32-, 64-, and 128-MB PC100 SDRAM at the 100MHz bus speed. The additional RAM should be 168-pin, 10ns, and 3.3V DIMMs. Use normal SDRAMs (PC-66) for 333MHz CPU´s and below, while using PC100 SDRAMs for 350MHz CPU´s and above. When installing DIMMS, ensure that you install only one type of DIMM. Do not combine PC-66 and PC-100 DIMMs.
Adding RAM is the most cost effective way to boost your computer's performance.
Enabling USB
To enable the USB ports follow these steps:
- To access the CMOS Setup Utility
Press [Ctrl] + [Alt] + [Esc] early in the boot-up process, after the first beep but before the operating system loads. It may be necessary to hold down the [Ctrl] + [Alt] keys while repeatedly tapping the [Esc] key in order to get the timing right.
- Select Onboard Peripheral Configuration
- Page down to Page 2
- Change USB Host Controller to [Enabled]
- Save and Exit the Setup Utility
How do I access my BIOS?
Resolution: You can access the BIOS by pressing CTRL+ALT+ESC as the system is booting. At the bottom of the second start up screen you should see "To enter setup, press CTRL_ALT_ESC".
Note: If the system displays the Acer Splash Screen, once you hear the beep, you should begin pressing CTRL+ALT+ESC. You may need to press CTRL+ALT+ESC continuously until you access the BIOS setup screen.
How do I disable the onboard video?
To disable the onboard video for this system, please follow the steps below:
- Press Ctrl+Alt+Esc to enter BIOS Setup Utility during system boot and before the operating system starts.
- Press Alt+F4 when the Setup Utility menus appears.
- Select Boot Options.
- Change Primary Display Driver to Auto
- Press Esc three times and choose yes to save CMOS changes.
