SUMMARY
The Compaticard IV, a floppy controller card, may exhibit a problem when running in a machine with an American Megatrends Inc. (AMI) BIOS when EMM386.EXE is loaded. The machine may fail to boot when the Compaticard IV device driver, CC4DRV.SYS, is loaded.



MORE INFORMATION
There is one solution and one possible workaround to this problem.



RESOLUTION
Micro Solutions has a patch available for CC4DRV.SYS, and will send out a corrected copy to customers who request it. Customers should contact Micro Solutions directly to obtain the new file.



WORKAROUND
Often the problem can be worked around by adding the parameter D=n to EMM386.EXE where n is a number greater than or equal to 128. For example:   device=c:\dos\emm386.exe d=128

The workaround should only be used as a temporary fix. The patch should be obtained from Micro Solutions as soon as possible.

Compaticard IV is a floppy controller card that can add up to four floppy drives (two may be external) to any IBM-compatible with an available expansion slot.
