its a long time since I had this sort of message and the brain is hurting. Do you have the hp device listed if not you can edit the files with notepad and remove the line. With windows 98 I seem to remember that it works ok without config.sys but I could be wrong. If this has only just started happening and you have not rebooted many times you can go back to a previous setting. This is like the precursor to system restore. In dos mode you type scanreg/ restore or scanreg/ fix.
