README.TXT -- NOTES ON YEAR 2000 FIXPAK FOR IBM PC DOS 7
This README.TXT file contains important information about the Year 2000
Fix Pak for PC DOS 7.
YEAR 2000 FIX PAK FOR IBM PC DOS 7
==================================
PC DOS 7 customers concerned about displaying or processing date
information after 1999 should upgrade to IBM's Fix Pak for PC DOS 7
or to IBM's PC DOS 2000 product.
Testing Your System for Year 2000
---------------------------------
After you install PC DOS 2000, you should thoroughly test the remainder
of your DOS environment to make sure dates are being processed and
displayed correctly.
If you experience a date-handling problem, ensure that your application
programs and hardware are handling the date correctly before contacting
PC DOS service and support.
Contact your application program manufacturer to see if there are any
known problems or an update available for your application program. PC
DOS 2000 cannot fix date handling problems that are being caused by
application programs. Only the application program manufacturer can
correct these problems.
PC DOS 2000 contains a fix for the "century roll-over" problem in some
BIOS programs. Your PC's BIOS may have other date-handling problems
even with this fix applied. Contact your PC manufacturer to see if
there are any known problems or an update available for your PC's BIOS.
How to Specify the Year
-----------------------
When you specify the year using two digits, PC DOS interprets 00 to 79
as years 2000 to 2079 and 80 to 99 as years 1980 to 1999. For
example, 7/15/78 (in mm/dd/yy format) is July 15, 2078 and 7/15/81 is
July 15, 1981. To avoid ambiguity errors, whenever possible, you
should specify the year using four digits. For example, specify
7/15/2078 for July 15, 2078. PC DOS does not support dates before
1980 or after 2079.

Installation
============
To install this Fix Pak, you will need:
- IBM PC DOS 7 installed on your system
- 2M bytes of free space on your system's Drive C:
- a formatted 1.44 MB diskette
Install Part 1
--------------
Create a Fix Pak diskette by following these steps:
1. Receive a language-specific PC DOS 7 Fix Pak file from IBM.
The file name is in the form DOS7xxY2.EXE where "xx" is the
language version of your installed PC DOS 7 as shown
below.
BR = Brazilian PO = Portuguese
DK = Danish RU = Russian
FR = French SP = Spanish
GR = German SU = Finnish
IT = Italian SV = Swedish
NL = Dutch US = English - USA and United Kingdom
NO = Norwegian
See README.JP for installation instructions for the Japanese Fix Pak
(CSD PC DOS J 7.00C/V); the following is not applicable.
2. Place a formatted 1.44MB diskette into Drive A:
3. From a DOS command prompt, enter:
DOS7xxY2 A:
Where "xx" is the two letter language code from the list above.
For example, to create an English version Fix Pak diskette in
drive A: you would enter:
DOS7USY2 A:
4. Label this diskette "PC DOS 7 Year 2000 Fix Pak"
Install Part 2
--------------
To install the Fix Pak, follow these steps:
1. IBM PC DOS 7 should already be installed on your system.
2. Insert the "PC DOS 7 Year 2000 Fix Pak" diskette into Drive A:
3. From a DOS command prompt, enter:
A:UPDATE drive:
Where "drive:" is the drive where PC DOS 7 is installed.
This is an optional parameter and defaults to drive C:
This program may take several minutes to update your system.
4. Remove the Year 2000 Fix Pak diskette from Drive A:
The update is now complete.
Eurocurrency Symbol Support
===========================
PC DOS provides support for the new Eurocurrency symbol defined by
the European Community as part of the European Monetary Union (EMU).
The symbol is provided in code page 850 at offset 0xD5. You can
invoke the symbol through the keyboard by using the same AltGr or
AltCar + character key sequence that is used for many other
country-specific symbols (the AltGr and AltCar keys are the same as
the right-hand Alt key). For additional information, see the
"Multiple Characters on a Key" section in the PC DOS 7 Keyboards and
Code Pages book which is sold separately. The table below shows the
particular key sequence for each country supported.
The symbol comes in 8x8, 8x14 and 8x16 pixel resolutions in code page
850 in both the EGA.CPI and EGAX.CPI code page information files, and
in 8x16 pixel resolution in code page 850 in the ISO.CPI file. These
CPI files are specified in the MODE command that is placed in the
AUTOEXEC.BAT file by SETUP.
SETUP automatically installs the Eurocurrency symbol support for
the countries listed in the following table. The support is activated
in the same way that code page 850 support is activated, as the
following examples shows.
Note: These examples assume PC DOS has been installed in the \DOS
directory on your hard disk. For additional information see the
section "Customizing Keyboards for International Use" and the specific
commands in the PC DOS 7 Command Reference and Error Messages book.
1) When you install any keyboard or country other than the default
U.S., SETUP adds a command to the CONFIG.SYS file to allocate a
buffer for the code page:
DEVICE=C:\DOS\DISPLAY.SYS CON=(,,1)
2) Commands are also added to AUTOEXEC.BAT to load, prepare and select
the code page:
MODE CON CP PREP=((850) C:\DOS\xxx.CPI)
