Hello Chris, It sounds like you have the older DOS version of our GPIB driver. The GPIB.COM is not meant to be executed, but is intended to be loaded in your config.sys file with a "DEVICE=C:\path\GPIB.COM" call.
If you are using an AT-GPIB card, note that you are using an obsolete card on your Windows 98 system. You can use the Win98 compatibility release to get this up and running. See here for instructions on doing this: http://www.ni.com/support/gpib/win98_95cr.htm Hope this helps. Scott B. National Instruments Applications Engineer
