and same error than using EMC 2.2.6 + 7i43 + Ted's sample.... What now?
OK, i'll try DOS, where do i get your utilities?
Download the latest 7I43 support package from:
http://www.mesanet.com/software/parallel/7i43.zip
Unzip this and copy these three files:
configs\hostmot2\epphm2\svst4_4b.bit
utils\epp\sc7i43p.exe
utils\epp\epptest.exe
to a working directory on some convenient media
Then run this command (assuming your parallel port address is set to 0x378)
sc7i43p svst4_4b.bit
If this succeeds you can try a loopback test:
epptest 378
EPPtest.exe writes 2 32 bit numbers (n and NOT n) in 2 hostmot2 32 bit
registers and reads them back, reporting and counting the errors. Every 100000
test it prints a loop count. This should run continously without errors

OK I tried rev B 7I43s (your card rev) with 2 motherboards using the VIA
VT82C686 (one VT82C686A and one VT82V686B). This is the same South bridge as
your motherboard.
Using a short cable (1 foot) I had no trouble configuring or doing a EPP
loopback test (I did 100 million EPP operations with no errors on both
motherboards)
There are a couple of possibilities:
1. The 7I43 you have is bad in some way (not too likely)
2. The cable you are using is not wired correctly or has a short (easy to do
with hand assembled flat cables)
3. The 7I43 you have somehow does not have the latest CPLD firmware that echos
the FPGA size (This should only apply to very early 7I43s and I think yours
is recent)
4. Somthing is wrong with your parallel port
Can you boot DOS on your EMC PC?
If you could try some of my test utilties Maybe I can get a better idea of the
exact problem.
