We are working on a PC Bell 640 and put in a sound card and a Diamond supra56k modem. When we boot we get a NVRAM data Invalid, NVRAM Cleared Press <F1> to enter setup, <ESC> to boot message. We removed the modem(ie physically take it out as well as remove it thru the device manager) The error goes away. any help would be greatly appreciated Thanks in advance Steve Coldwell
