The following symptoms may occur:

• The "PC Coax Adapter Board not present" error message occurs.
• The "Adapter memory failure" error message occurs.
• The "Coax Adapter system resource conflict detected" error message occurs.
• A session screen is blank and the connection status row is blank.
• The "Error loading adapter - Driver was NOT installed." message occurs.

These symptoms may be caused by a conflict between the memory range of the FORVUS Coax adapter and the shadow RAM on the Pentium PC. Many Pentium PC's will shadow RAM used for its plug in adapters on its internal bus. The FORVUS Coax adapter uses the memory range CE00 through CFFF on the system bus. Most Pentium PC's will shadow or disable this range by default to reserve this space for internal use. Newer PC's with Plug-n-Play may refer to this setting as ISA Shared Memory Size and ISA Shared Memory Base.

Resolving Conflicts

1) If you are using a memory manager with Windows 95/98, be sure to exclude the memory address range the FORVUS Coax Adapter requires. In the CONFIG.SYS file, edit or add the following statement:

              device =   c:\path\emm386.exe X=CE00-CFFF

2) Depending on the model and manufacturer of your PC, you will need to access the setup of your system's BIOS setup.

• Locate the Disable Shadow Memory BASE option
• Select CC000h as the base address
• Locate the Disable Shadow Memory SIZE option
• Select 16K

3) If your PC has Plug-n-Play, the following options may be found instead:

• American Megatrends (AMI) BIOS
• Select the Plug-n-Play option
• Select the ISA Shared Memory size option
• Select 16K as the size
• Select the BASE address as CC00

or:

• Award Software (AWARD)
• Select PNP/PCI Configuration
• Select Resources Controlled By Manual
• Select Used MEM base addr to CC00
• Select Used MEM Length 16K

4) Save these BIOS setting and reboot your PC

5) If you have not registered your Adapter with the Windows 95/98 Control Panel settings, refer to Technical Bulletin 101 found on this website
