I have been playing with this system for a few weeks. I am trying to connect it to the peer to peer network. I recently installed the 3Com 16port hub with nic's, no prob. But when I tried to add another system, no luck. I even went to the extreme ofchanging the motherboard & cpu. I have also tried 2 different nic cards without success. Changed the PCI slot, reinstalled software and the only error that has been given was that the EMM386.EXE installed will not allow the NIC to operate. This is anew 1 for me. Does anyone have any idea about the EMM386.EXE file in windows 98 SE.

Remove the card completely from control panel-system-etc, network neighborhood, and then run msconfig at the start-run prompt.

Using the selective startup options, eliminate the use of config.sys and autoexec.bat. Neither file is needed in windows 98, as long as you are not using a dos based program that requires emm386.

Re-boot, and re-install the card.

Another possibility is that the bios is attempting to assign an irq to the card, which conflicts with windows. Try turning off PNPOS Y/N? in the system bios.

You can also manually set an irq and IO address for the card with the dos based configuration utility that ships with the card.... 3cxxxcfg.exe where xxx is the card number, ie 905, 509.

As a side note, 3com is really beginning to get a bad rep in the tech world on it's NIC cards. They used to be the most reliable, easiest to configure and install, but now,
most of the techs I know are trending towards yanking the card and installing another brand rather than hassle with 3com.
