HDDs no longer recignized

[Ajax36]

I have an old Midwest Micro Elite computer that I have not fired up in about 3 months. I started it up today but the BIOS no longer thinks I have any hard drives installed. It indindictes only the 2 Floppys are installed. It also does not think I have a mouse installed either. (PS/2).
And one more clue the BIOS states that the PCI IDE Interface is disabled for some reason. I thought the CMOS battery might be dead but the Date and Time are still accurate.

Does anyone have any ideas what might be causing these symptoms?

Thanks in advance for any suggestions.

What happens if you set the bios to defaults..maybe the cmos battery ...could be on its way out ...its recommanded that the cmos battery be renewed after three years ...check all the ide cables to the mobo/drives and the good old dust comes into play also+ storage where was it stored? damp wet etc..
