Memory
The system memory is upgradable to a maximum of 256MB via two 168-pin DIMM sockets on board. These DIMM sockets accept 128MB, 3.3V, 10ns Synchronous DRAM modules in capacities of 8-, 16-, 32-, 64-, and 128-MB.
Known Issues
Setting Up USB in Windows 95
When going into the BIOS to enable both USB function and USB legacy mode, system boots Okay. Windows 95 detects the ports and attempts to install the USB drivers and then attempts to install the Standard OpenHCD USB Host Controller driver, but cannot find the OPENHCL.SYS driver. The USB Supplement that is a part of the preload incorrectly copies the needed OPENHCI.SYS driver to the \WINDOWS\SYSTEM directory instead, thus necessitating that the installer be pointed to that directory.
Resolution: Edit memory range to FFFDF000-FFFDFFFF to remove conflicting addresses. The USB Root Hub will then properly install with no conflicts. To do this from the desktop:
- Click Start, then on Run.
- Type in SYSEDIT and click on OK.
- Go to the file called CONFIG.SYS and locate the line starting with DEVICE=C:\WINDOWS\EMM386.EXE...".
- Place your cursor at the end of this line. Press the spacebar and then type X=FFFDF000-FFFDFFFF.
- Click on File, the save.
- Close SYSEDIT.
- Shutdown Windows and reboot the computer.
Cause: The default setup chooses memory range 00000000-00000FFF, but that conflicts with the System Board Extension for the PnP BIOS.
How do you access the BIOS?
The BIOS can be accessed 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.
