This error message, along with the description of the system, suggests that you
may not have configured the Token Ring card. Configure the card using the IBM
Reference Disk, prior to installing AppleShare PC.
Check to see if the files on other disks that may have shipped with the Token
Ring card are already contained on the Reference Disk. If not, copy them to
the Reference Disk. Make a note of the parameter settings for the card,
particularly the memory locations you assigned. You'll need these later, when
you install the AppleShare PC software. Start up your PC with the Reference
Disk and install and configure the Token Ring card.
