[comp.protocols.tcp-ip.ibmpc] Racal Interlan & Windows 3

ingea@IFI.UIO.NO (Inge Arnesen) (11/09/90)

We have a configuration with a Racal Interlan card  and FTP SW packet
driver and TCP/IP software and have the following problem:

While running Windows 3.0 in 386 enhanced mode, all network utilities
stops working. F.ex. Start up a DOS box from Windows 3 and run the
PING utility. It will not be able to reach any machines. Other 
programs written for FTP SW (loaded resident before Windows 3) also
stops working (this is a resident Telnet program) after Windows 3 is
started in enhanced mode.

It works perfectly with Windows 3.0 in real or standard mode, so it
seems that the 8086 hardware virtualisation creates the problem. We
have tried different DMA channels and other IRQ's, but the problem
remains. After tracing it with a debugger, it seems that the DMA
transfer fails somehow. 

We have also tried it with Racal Interlans own TCP/IP, but it has the
same problem as well. Any suggestions ?
