This board has a NON-STANDARD caching system which is incompatable with MOST
dual ported memory cards.  I have extensivly tested Mylex boards and had 
BAD experiences with all of the caching boards. Some companies 
make custom work arounds for their cards to support the mylex board, 
but only a few.  I gave up on Mylex and started using AMI boards with
NO problems with caching and dual ported memory.

Chances are that this will need one of the interrupts that your dual serial
card needs.

You might want to consider the Megaport serial board.  This board is the 
fastest serial board around and it will work fine with the bus mouse.

Nice choice.

Interactive (in my expierence) is a better choice.  It has Xenix binary 
compatibility as well as X11R4 and Motif (all of which I am running). It
may cost a little more, but it is a great product.  I have installed 
MANY systems with Interactive, and have always been pleased.  I have
also used SCO and thint that Interactive is a smoother product.

Yes, you can set up different partitions that you can switch between
via fdisk.  You can also mount MS-DOS partitions from within
Interactive by using the mount -f DOS command and then access the
data from unix or vpix.
