Another OS problem

Hi folks, Shouldn't really post this one here, I suppose! A governor's Win98 installation insists that and ISDN device should be loaded every time the machine starts. She hasn't got anything like ISDN anywhere and the hardware inventory for her machine doesn't help. Any ideas how it can lose this error without losing the whole OS (which was my suggestion!). The OS has been reinstalled. -- Best wishes, Derek Harding, (BA MIAP) ICT & Network Manager hardingd@warlingham.surrey.sch.uk
