EPSON Product Support Bulletin Subject: Proper Method for Running Benchmark and Diagnostics Programs Date: 06/04/93 Page(s): 1 of 1 PSB No: S-0158 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.

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”. The expanded memory is divided into 16K portions called “pages”. The computer accesses these pages through a “page frame” or “window” which is 64K of memory located between 768K and 896K in 80286 - based systems and between 800K and 960K in 8086 - or 8088 - based systems. 16K pages of memory are allocated for an application’s use and the EMM (Expanded Memory Manager) handles the job of mapping the pages in and out of the page frame as they are needed. However, in order to make use of expanded memory, the software must be written to take advantage of the EMS. Software such as Lotus 1 - 2 - 3, Microsoft Windows and Borland’s SideKick Plus make use of expanded memory. EMS is limited to 8Mb of expanded memory. What is EEMS? A superset of EMS, AQA EEMS (AST/Quadram/Ashton - Tate Enhanced Expanded Memory Specification) provides greater flexibility in the mapping of expanded memory. However, it also uses the technique of “bank switching” and has its own memory manager which accommodates such specially written software as Quarterdeck’s DESQview. EEMS is also limited to 8Mb of expanded memory. 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. Examples of currently available software that can switch into protected mode to use extended memory are Framework II, AutoCAD, the VDisk RAM disk and Xenix OS. How does LIM EMS 4.0, the latest version, differ from the earlier version, LIM EMS 3.2? EMS 4.0 supports up to 32Mb of expanded memory where EMS 3.2 supported only 8Mb. EMS 4.0 has been changed to make it easier for applications to share expanded memory. In EMS 4.0, page mapping has been streamlined and new functions allow application programs to dynamically increase and decrease the amount of expanded memory allocated to them. In previous versions of EMS, the page frame was located in an unused 64K block of memory between 640K and 1Mb. EMS 4.0, subject to limitations in the system hardware, supports the page frame anywhere in the first 1Mb of memory. Before EMS 4.0, the page frame held four pages. Now you can define a page frame of up to eight pages in memory above 640K. The size of the page frame is limited only by the amount of available memory. There has also been a change to support the smaller than standard (16K) memory pages used by some expanded memory boards. Is EMS 4.0 compatible with my old expanded memory board? The EMM 4.0 driver works with existing hardware. You don’t need to buy a new expanded memory board. However, until you use applications that have been written to take advantage of EMS 4.0, you probably won’t notice much improvement in performance over your older version.

They have been removed from the list because Micron no longer produces ISA memory boards. Q12. A. How do you expand the memory of the Equity 386/20? Memory expansion in the Equity 386/20 can be accomplished by adding SlMMs (single in - line memory modules) to the CHET - RM board. Both 256K and 1Mb SlMMs are available from Epson America. The 256K SlMMs are sold in 1Mb kits and the 1Mb SlMMs are sold in 2Mb kits. Compatible third party 1Mb SlMMs are available from Matsushita, Toshiba and CDC Enterprises. You can also use third party memory expansion boards such as those listed above for the Equity II +/Ill +. PSB No: S-0047C 5 of 6 Page: Q13. A. Are there any guidelines to installing the SlMMs in the Equity 386/20? Yes, when SlMMs are installed to increase memory beyond 1Mb, they must be installed so that banks of SlMMs are installed as matched pairs. See the matrix below: Memory Bank 0 1MB 2MB 4MB 4MB 8MB 10MB 16MB 4X256KB 4X256KB 4X256KB 4X1MB 4X1 MB 4X1 MB 4X1 MB Note: Bank 1 Bank 2 Bank 3 4X256KB 4X256KB 4X256KB 4X256KB 4X1 MB 4X1 MB 4X1 MB 4X256KB 4X256KB 4X1 MB 4X1 MB Refer to PSB S - 0095 for 18MB RAM Setup information. Q14. Is there a driver supplied with the Equity 386/20 to allow the use of the extended memory as expanded memory? A. Yes, the Equity 386/20 system software includes the device driver EEMM386EXE. This driver emulates LIM EMS 4.0 memory using the extended memory supplied by the additional SIMMs. It will support only the onboard memory above 1 MB, up to 15MB. This is the maximum memory that can be installed on the CHET- RM board. It will not support memory installed on memory expansion boards. Q15. Are there any expanded memory boards that are compatible with the Equity LT? A. No, the option slots on the LT require a special connector. The hard drive controller and the LT cartridge modem are the only option cards currently available from Epson America. Q16. What expanded memory boards are compatible with the Apex by Epson? A. The Above Board PC from Intel Corporation has been tested by Epson in the Apex. 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. For example, the Intel Above Board 288 and Above Board Plus allow you to set up the bus speed and chip speed in their installation programs. Q19. What is meant by backfilling memory when using software such as DESQview? A. Backfilling is a function of many expanded memory boards which allows a portion of the board’s memory to be used as conventional memory. In this way, you could turn a 256K system into one with 840K memory or more. In certain situations, you may want to disable some of the computer’s conventional memory and the use the memory on the expansion board (i.e. DESQview). Q20. Which Epson computers have memory settings that allow backfilling memory? A. The Equity I, Equity I +, Equity II + and Equity Ill + allow backfill. The Equity I comes with 256K standard and the Apex comes with 512K, thus allowing backfill. The Equity I + has DIP switch settings allowing system memory to be disabled to 256K or 512K. The Equity II+ and Equity Ill + have jumpers on the system memory boards to allow memory to be disabled to 256K and 512K. EPSON EPSON AMERICA INC.

NUMBER: S-0037 Epson's MS-DOS II and Equity On March 1, 1988 we discovered that the system date did not change correctly to 3-1-1988, but indicated 2-29-1988. As you may have guessed, MS-DOS 3.1 did not handle the February 29th "leap day" change correctly. Both the Equity II and Equity III use a Real Time Clock/Calendar with CMOS RAM to retain the date and time after it is set with the SETUP utility program. Even though the RTC has the correct date (03-Ol-1988), DOS interprets it as 02-29-1988. The easiest method of correcting this anomaly is to set the date in the RTC's CMOS RAM one day ahead as follows: 1. 2. 3. 4. 5. Run the Select Set the EXIT to Re-boot "SETUP" utility program. REAL-TIME CLOCK. DATE to the current date + one. save the new date. the system! When MS-DOS 3.1 retrieves the date from the RTC it subtracts the extra day and will display the correct date for system operation.

SERVICE DEPARTMENT SUPPORT PRODUCT 6/8/87 DATE: EPSON SUBJECT: EQUITY ENHANCED KEYBOARD NUMBER: COMPATIBILITY S-0012 The purpose of this bulletin is to provide information regarding style Equity Plus series the compatibility of the enhanced "AT" keyboard with the Equity family of computers and a general statement on software support. With the introduction of the Equity It and III+, Epson brought out an enhanced keyboard design - very similar to the enhanced keyboard introduced by IBM on the Model 339 AT. There are a couple of areas to make note of. 1. Keyboard Compatibility The enhanced keyboard cannot be used on an Equity -‘I, II or III. The enhanced keyboard (as with IBM's) requires explicit ROM BIOS support. The Equity It and Equity III+ incorporate this support; the earlier machines do not. It is possible, however, to use a third-party "enhanced-style" keyboard (such as the Datadesk Turbo-101) which offers switch selection for PC/XT or AT usage. (Please note that early versions of the Equity I and II did not support any third party keyboards.) The correct jumper Equity I: Equity II: settings for non-Epson keyboards are: J2 and J3 jumpered J 3 , J4 and J5 set for position 1 Also note that once the above jumper changes have been made, attempting to use the Epson keyboard will result in damage to the keyboard-and main board. 2. Software Compatibility Not all applications "know" about the enhanced keyboard. The and mapping are subtly different. If you experience scan codes difficulties with certain applications (particularly any that re-program the keyboard), contact the software vendor and ask about enhanced keyboard support.
