Rampage! AST Part Number 202073-001
The Rampage is a memory enhancement board designed for use with the IBM PC,
XT, and 100% compatibles running at a speed of 4.77MHz. The Rampage can be
populated from 256K to 2048K using industry standard 256K DRAM chips of at
least 150ns speed. The memory standards supported by the Rampage include
conventional (640K base), LIM 3.2, EEMS, and LIM 4.0. Extended memory can be
emulated by using the REX.SYS device driver. In order to access any
non-coventional memory, the REMM.SYS device driver must be used.

NOTE: The maximum amount of conventional memory in an IBM PC/XT is
640K. SW7 & SW8 define the amount of conventional memory
available to the PC from the Rampage board. In some cases, the
total of existing PC memory and Rampage conventional memory may
add up to more than 640K. In this situation, conventional memory
stops at 640K and the balance becomes available as expanded
memory.
JUMPER SETTINGS
The only user-configurable jumpers on the Rampage are the three pin jumper
labeled "E1-E2-E3" and the two pin jumper at "E8-E9". By attaching E1-E2,
Dual Page Mode is disabled, allowing only one set of mapping registers for
expanded memory. Attaching E2-E3 enables Dual Page Mode, allowing two
mapping registers. AST recommends two mapping registers, as they are
useful for multitasking purposes.
Attaching E8-E9 enables parity checking. It is strongly recommended that
parity checking is always enabled.
