- GENERAL
- INFORMATION: Listed below, are Proteon 16-bit ISA cards that do
- busmastering:
-
- P-1347, P-1346, P-1345, P-1344
-
- These cards will not work in an EISA machine (or any other
- machine) with over 16MB of RAM with NetWare 386 v3.1 unless
- the STARTUP.NCF contains the following setable;
-
- "SET AUTO REGISTER MEMORY ABOVE 16 MEGABYTES = OFF."
-
- The reason for this parameter is that NetWare v3.1
- arbitrarily assigns DMA and busmastering memory addresses
- anywhere it likes. These cards will not see memory
- addresses above 16MB.
-
- The NetWare 386 v3.1 README file states the following:
-
- "EISA computers: If your EISA file server contains more
- than 16MB of RAM, do not use 8-bit PC or 16-bit AT boards in
- the file server if the board uses busmastering or DMA.
- Check with the manufacturer for more information."
-
- This can apply to any file server that contains more than
- 16MB of RAM, not just with EISA machines. If you use 8-bit
- or 16-bit AT cards, the above "SET" command must be present
- in the STARTUP.NCF or these cards will not work in file
- servers with over 16MB of RAM. This will force the DMA or
- busmastering memory assignments made by the operating system
- to occur below the 16MB RAM location.
