Memory Upgrade
The system is upgradable to a maximum of 256MB via two 168-pin DIMM sockets on board. These DIMM sockets accept DRAMs with 8, 32, 64, and 128MB capacities, 60ns (nanoseconds) or less access time, and ECC, PC100Mhz.
Adding RAM is the most cost effective way to boost your computer's performance.
BIOS
How do I enter the BIOS Setup Utility?
You can access the BIOS Setup Utility 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.
