boot up error message.

Hi, i’m running win98se. I have taken away the win98 splash screen and have noticed through all the goobldygook when the pc is booting, this message appears: “boot from ATAPI CD-ROM: failure, Starting Windows98”. The pc starts fine everytime, no problems. I have re-installed the pc for a few unrelated reasons and it has been there also. I’m not sure what other info i can give. Its an OEM installed pc. I’m not sure what other info i can give. Any help on this is really appreciated. Cheer’s. J.
