PCI Caching Controller not recognized

I just installed a US Logic APT-8400+ PCI IDE Caching Controller.  I placed my Mitsumi 4x IDE on the first IDE port on the card (as instructed, and it is the only way the CD ROM works in ANY mode, DOS or WINDOWS), and a 1.6 and 1.08 GB IDE drive on the second port.  I had to install their ATAPI driver to get the CD-ROM to be recognized, and all was well, until I fired up Win95.  It loaded slowly, and when it stabilized, it said it was running in MS-DOS compatability mode.  My CD-ROM was not available, and system performance was very bad.  My question is:  1) where do I get the protected mode drivers for this card, or 2) is there an easier solution that someone else has already thought of?

Did you have to install the DOS Atapi driver for Win95?
It shouldn't be necessary, Windows should be able to recognize it. You should put them only in CONFIG.DOS/AUTOEXEC.DOS.
Since this is probably not the answer, I have only a long shot.
1. Try http://qlink.queensu.ca/~3dre/mitsumi.html (the unofficial Mitsumi web page) or
       http://www.mitsumi.com (the new web site - I couldn't access it yet, probably hasn't updated the DNS entry yet)

They have mentioned a few problems with Intel Triton VX chipsets, and HX too. You'll find information there about this. The usual problem with the VX chipset is a Windows 95 bug that sometimes (so, the usual in W95...) prevents it from reading the second EIDE channel. There is a fix at microsoft.com, but I think it is mentioned at mitsumi too (if not, try http://qlink.queensu.ca/~3dre/whatsnew.html).

Well, Mitsumi home page should solve all your problems ;-)
Hope it helps.
