8MB (2 x 4MB Fast Page RAM in Banks 3&4) supplied with machine. To upgrade memory on this machine the user must insert 72 pin PARITY SIMMs IN EQUAL SIZE PAIRS into spare 72 pin SIMM sockets. The chips must have an access time of 70 nanoseconds or less. RAM can be upgraded to 128MB using 1MB, 2MB, 4MB, 8MB, 16MB & 32MB Fast Page Mode or EDO SIMMS, in identical pairs, in either Bank0 (SIMM 3&4) or Bank 1 (SIMM 1&2). Each bank is 2 SIMM sockets.

Known Issues
Problems Accessing HDD
If there is a problem with formatting or accessing the HDD - then look in the BIOS in the PCI/GREEN FUNCTION SETUP, look at IDE PRIMARY MASTER PIO and select either MODE 3(1gig) or MODE 4 (540mb) depending on HDD size.
If that doesn't work, it may also be worth going into the BIOS again, and in the PCI/GREEN Functions change the IDD Block mode to disabled. Save settings and exit.
Installing an Opti Soundcard
- You should have the latest drivers on a floppy diskette ready for installation.
- Start Windows 95 and proceed to the Control Panel folder and select (double click) the SYSTEM icon.
- Select the Device Manager tab to display the list of devices currently present on your system.
- Check to see if you have previously installed the device. Usually, the device name starts with "OPTi .. SoundSystem." If a previous instance of the device does not exist, exit the System Properties dialog box and skip the next section.
- If the device has been installed previously, double click on the device name to expand the list of sub-devices and select "OPTi .. Sound System:..." to remove the set devices plus this parent device. You will not be able to remove child devices which are controlled by this parent device unless this parent device is removed. Check also to see if you have previously installed any Windows Sound System or Sound Blaster audio devices or their compatibles, and if so, please remove them from the list. Once the devices has been removed, you must restart Windows 95.
- Select (double click) the Add New Hardware icon located in the Control Panel folder to add/update the new device and it's associated drivers.
- When prompted by Windows 95 for the Auto-Scan option for detecting new devices on your System - select NO and proceed to the next page.
- Windows 95 will display a list of known devices that you currently wish to install. Select "Other Devices" even though the name of the device is included in the list. This forces Windows 95 to perform a fresh install for your device. Select Next to proceed.
- Windows 95 will again display a list containing manufacturer names and at which point you should ignore the list and select the "Have Disk..." button. This tells Windows 95 to read special installation instructions from your diskette to correctly install the drivers for your OPTi Sound device. You will have to direct Windows 95 to the proper location of the floppy diskette.
- Once information from the floppy diskette has been read by Windows 95, a list of devices available for installation will be displayed. Just select the basic option which includes only the Sound/Game support.
- Select Next and Windows 95 will proceed to install the drivers needed for your device and configure your device accordingly. Once your device has been successfully configured, Windows 95 will prompt you to restart your system - select No to skip this restart process since you should have your Sound Card properly plugged in and installed. If however your Sound Card has not been correctly installed, you will have to select Yes to restart Windows 95.
- Install REAL MODE DOS Support: If you prefer to use your Sound Card in Real Mode DOS environment, you have to select "Yes" at the "Restart System" prompt in the previous section. During the reboot process the DOS Installer will be invoked automatically. Please follow the instruction of DOS Installer and it will setup the sound card properly for your Real Mode DOS Games or Applications.
The DOS drivers will add the following lines into the AUTOEXEC.BAT file (NB. Path names may be different, depending on version of Opti card) -
SET SOUND16=C:\OPTI924
SET BLASTER=A220 I5 DI T4
LH C:\OPTI924\SNDINIT.COM /B
