Known Problems and Limitations
If you set the ROM location to 0xCE000, the Token Ring board will use 24 Kbytes
starting at that location, so it will use all addresses in the range 0xCE000–D3FFF.
Note - In most systems, memory from C0000 to CB000 is used as video RAM.
Do not configure any device at I/O address 0x220–0x227 if there is a Token Ring
in the system. For example, because the default address for a Sound Blaster card is
0x220, either move it to port address 0x240 or remove it from the system.
If the Token Ring board is not connected to a hub on startup or netboot, an error
message is displayed. In the case of a netboot, the boot process panics. Make sure
that the Token Ring board is connected to a hub and that the hub is active.
The adapter’s receive speed is directly related to the amount of RAM the adapter
is using. If your adapter performs poorly, use 32 Kbytes of memory instead of the
more usual 8 Kbytes. Use the manufacturer’s configuration program to set the
card’s RAM.
Configuration Procedure
1. Follow the manufacturer’s documentation and use the manufacturer’s setup
software to configure the card.
