Windows 98 complains about missing .CAT files
Files with the .cat extension are signature files issued by Microsoft that indicate a device driver is
WHQL certified. If a driver is not certified, there will be no .cat files available.
When installing drivers in Windows 98 or Windows ME, the user is prompted to locate the .cat files
if the operating system cannot find them. If the driver is not certified but you wish to install it
anyway, the files may be skipped by clicking the "Skip" button.
