Total System Memory
The entire main memory is composed of the total DynamiCache plus DRAM subsystem.
Refer to the chart below for possible memory configurations, from 4MB to 32MB. The
system auto detects the memory size.
For maximum efficiency in system performance, OISI strongly recommends a minimum
of 8MB DynamiCache. Most of the advanced operating system application software
(Chicago, Daytona, Windows NT, Windows for Workgroups, OS/2 2.11, et al) require a
minimum of 8MB system memory to run efficiently. It would be to the user’s benefit to
install 8MB DynamiCache to allow the entire program set and data set to run within DCA2.

ISA Slots
ISA is the abbreviation for Industry Standard
Architecture. It refers to the bus architecture
originally created for the IBM XT and AT
computers. The XT had an 8-bit data path and
the AT a 16-bit data path. The AT has become
the industry standard because of the large
number of peripherals designed to connect to it.
The Hippo DCA2 has six 16-bit ISA slots and
two 8-bit ISA slot.

VESA Local Bus
VESA refers to the Video Electronics Standards Association, an organization of major PC
graphics vendors devoted to improving graphics standards. The Hippo DCA2 has three
32-bit VESA Local Bus (VL) extensions and is one hundred percent compatible with the
specification set forth by the Video Electronics Standards Association.
