Norton Ghost 8 & Boot Disk Drivers

I am trying to Add a new NIC Boot Disk driver for some new IBM S51s and I am having trouble creating the NDIS driver. I have tried copying the drivers from another S51 and downloading from IBM’s support site but without luck. The error message I get is ‘Bad or Missing \NET\B57WIN32.INF Error in configuring Line 12’

Any advice

Mike
