Product Support Bulletin

Subject: Proper Method for Running Benchmark and Diagnostics Programs

Date: 06/04/93

PSB No: S-0158

Page(s): 1 of 1

Originator: MWT

This bulletin describes the proper method for running any benchmark or diagnostics

programs. This applies to any computer system.

In most cases, the computer should be started using an MS-DOS boot diskette

that’s ‘clean’ -

in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.

The appropriate executable can then be run, either from diskette or hard drive.

There will be some exceptions to the above rule. In attempting to benchmark or

troubleshoot any add-on that requires a device driver (CD-ROM, local area network,

etc.), obviously the necessary device driver(s) must be loaded. Also, some

programs will require a minimum number of FILES or BUFFERS to be defined in

the CONFIG.SYS file. Such programs will usually display this requirement if they

are run without the necessary CONFIG.SYS file.

For the most consistent results, use the absolute minimal boot configuration that’s

allowed by the hardware being tested.

EPSON EPSON AMERICA, INC. Product Support Bulletin Subject: Equity 386/20 Questions and Answers PSB No: S-0086A Originator: PNM/JAD Date: 8/7/91 Page(s) : 1 of 8 Q1. What microprocessor does the Equity 386/20 use? A. The Equity 386/20 utilizes an Intel 80386 microprocessor running at 20 megahertz. Use of this chip allows for a high powered, high speed 32 bit machine. Q2. What is “Shadow Ram”? What does it do and how does it work? A.
PAGE 20
PSB No: S-0086A Page: 2 of 8 Q4. What is page interleave memory architecture? A. Page/interleave memory architecture is a method for increasing memory access time. Memory that is interleaved provides faster retrieval during sequential memory access. Interleaved architecture requires at least two banks of memory. Even memory addresses are in the first bank, odd memory in the second. While the processor is accessing memory in the first bank, memory in the second bank is being prepared for immediate access.
PAGE 21
PSB No: S-0086A Page: 3 of 8 Q7. What is the Auto Speed function? A. The Equity 386/20 is capable of operating at 20 MHZ or 8 MHZ. Some copyprotected applications require the computer to run at 8 MHZ while accessing the program diskette. By enabling the Auto speed function the computer automatically switches to 8 MHZ when accessing the diskette drive. it then switches back to 20 MHZ for optimal performance. Auto speed is accessed through the setup program under the Auto speed option. Q8.
PAGE 22
PSB No: S-0086A Page: 4 of 8 Q12. What extended hard drive support is available in the new ROM BIOS drive tables that come in the Equity 386/20? A. The Seiko-Epson BIOS will directly support hard drives that range in size from 10 Mb up to 153 Mb. Larger size drives can be used by using a supplementary BIOS for the hard disk controller that is installed in the machine. There is direct support for the Seagate ST-251 and the ST-4096 hard disks as well as several ESDI drives.
PAGE 23
PSB No: S-0086A Page: 5 of 8 Q16. What math co-processor should be used? Is the Weitek 3167 math coprocessor supported? A. You should use the Intel 80387-20 MHZ numeric co-processor for best results. The Weitek 3167 math co-processor is not supported. Q17. Can 3 floppy drives be installed to support the different media types available? A. No. The BIOS only supports 2 floppy disk drives. Q18. Can the floppy drive controller be disabled in the Equity 386/20? A. Yes.

Product Support Bulletin Subject: Using Expanded Memory with Equity and Apex Computers Date: Page: 3/2/90 1 of 6 Q1. A. Q2. A. PSB No: Originator: S-0047C KAS ‘/“p& What is Expanded Memory? Conventional memory, managed by MS - DOS, is limited to 640K. In response to the need for greater amounts of accessible memory, the LIM EMS (Lotus/Intel/Microsoft Expanded Memory Specification) was introduced in 1984. EMS, version 3.2, provides usable memory beyond the 640K limit through “bank switching”.
PAGE 41
PSB No: S-0047C Page: 2 of 6 Q3. A. Q4. A. Q5. A. What about the 155Mb RAM listed as the maximum for the Equity III +? This larger amount of RAM is the maximum usable memory range for an 80286 microprocessor and generally refers to extended memory. Extended memory starts at the 1Mb boundary and extends out to 16Mb. As it requires a 24 - bit address to access memory in this range, extended memory is handled by the protected mode of the 80286.

PAGE 45
PSB No: S-0047C Page: 6 of 6 Q17. Are there any general guidelines for determining the chip speed to install on the memory expansion boards? A. Yes, if the CPU speed is 8MHz or less, use 150ns RAM chips. If the CPU speed is 10/12MHz, use 120ns RAM chips. Q18. Is there anything that should be kept in mind during the installation procedure for the memory expansion boards? A. Yes, when installing the memory boards in the Equity II + and Equity Ill + (12MHz models), remember that the bus speed is 12MHz.
