The advent of Lotus 1 -
2
- 3 Release 3.0 has raised a number of questions
regarding memory management for the Epson Equity computers, specifically the
Equity 386/20, Equity 386SX and Equity Ile. The purpose of this document is
to discuss the memory requirements for Lotus 1 - 2 - 3 Release 3.0 and
recommendations for installation.
Because programs run significantly faster with extended memory, Lotus
recommends that you configure as
much
memory as possible as extended
memory.
When installing Lotus 1 - 2 - 3 Release 3.0 on the Equity 386/20 or the Equity
386SX, do not use the EMS managers supplied with the system software
(EEMM386.EXE for the Equity 386/20 and EMM386.SYS for the Equity 386SX).
Neither of these EMS managers support the Virtual Control Program Interface
(VCPI) which is required for compatibility with
Lotus
1 - 2- 3 Release 3.0.
NOTE: Should you require an EMS manager for your Equity 386/20 or Equity
386SX, there are third party software packages available that are compatible
with Lotus 1 - 2 - 3 Release 3.0.
Two such packages are
version 4.03
or later, and Quarterdeck Expanded Memory Manager
(QEMM)
version 4.2 or
later.
Do
not
use VDISK with the /E switch when running Lotus on the Equity
386/20. Though Lotus Release 3.0 will load, it will overwrite any data in the
RAMDISK. VDISK supplied for both the Equity Ile and Equity 386SX is
compatible with Lotus 1 - 2 - 3 Release 3.0 and does not have a problem with
ovewriting data in the RAMDISK.
When installing Lotus 1 - 2- 3 Release 3.0 in the Equity lIe, use the EEMM286
memory manager in the hardware - emulation EMS mode. To do this, set
memory as expanded memory on the Equity lIe and do not specify the
expanded memory size.
When the Equity lIe has only 1Mb system memory,
you must select on - board memory type 5 in SETUP. When the Equity lIe
has more than 1Mb
of
system memory, you
must select
type 3, 4 or 5.
Avoid the use of HDCACHE when installing Lotus 1 - 2 - 3 Release 3.0 on any
of the Equity computer systems discussed in this document.
