Hello,
We have had PC-NFS 3.0.1 installed for quite some time now,
but recently I have wanted to replace the board-level drivers
with packet drivers, to get the use of such facilities as other
telnets (NCSA, CUTCP, etc.) and SOSS.
However, even though I believe I have installed the packet drivers
for exactly the same configuration as was used before, it isn't
working. This is essentially the change:
CONFIG.SYS before after
device=\nfs\pcnfs.sys /f20 /b0 -- same --
device=\nfs\sockdrv.sys -- same --
device=\nfs\wd8003e.sys /i3 /mb000 device=\nfs\pktd\pktd.sys
AUTOEXEC.BAT
nfsrun wd8003e 0x78 0x03 0x280 0xb000
nfsrun
(the WD8003E call has also been tried with
-o, -n, and -d, with mixed effects)
PKTD.SYS and WD8003E seem to install alright -- the only odd thing I've
noticed in their reports is that WD8003E claims to be installed at
interrupt 9, not 3. I'm sure the 0x280 is correct because the board's
ethernet number is reported at installation; but if I try changing
the 0x280, it reports instead that no WD8003E is found at that address.
But this arrangement does not seem to contact the net.
Using TRACE and DUMP, I find that sending is the only action that
gets recorded: there is no indication of any packets' being received.
This suggests to me that the interrupt being raised when packets
come in is not the interrupt that WD8003E.COM has been told about.
Are there any fine points that anybody can tell me about this
conversion? The installation in its pre-conversion form works just
fine (in case anybody was dubious about putting the board's buffer
at B000 -- none of our machine has a monochrome monitor, so this area
is being left unused). And each time, after I have grown tired of
experimenting with the packet driver version and comment out the
lines that try to install it -- going back to the simple PC-NFS version --
everything resumes working with no problem.
It is possible I have got a version mismatch of PKTD.SYS to WD8003E.COM .
Does anybody know if that would cause problems, and what the right
versions of each should be for PC-NFS 3.0.1 ?
Any assistance much appreciated.
