Page(s): 1 of 2
This bulletin announces the availability of enhanced display drivers for the Epson EL
4S/33+ and EL 486UC+ computers running IBM's OS/2 2.0 or 2.1. The 32-bit
Service Pack for version 2.0 from IBM must be installed before installing the new
display drivers. Also, the current system configuration must be VGA or SVGA.
These drivers can be downloaded from the Epson Bulletin Board System (BBS) that
can be reached at (310) 782-4531. They are located in one self-extracting file
(OS2_20.EXE for Version 2.0) or (OS2_21.EXE for Version 2.1) in file library
DRIVERS. Once downloaded, extract the files to a high-density diskette (1.44MB)
by entering the command:
OS2_20 A: or OS2_20 B:
OS2_21 A: or OS2_21 B:
depending on which disk drive is being used. The diskette must have the volume
label OS2 DRVS.
To install a driver, place the Display Drivers diskette into drive A:. Open an OS/2
session, either full-screen or window, and enter the following command:
A:INSTALL A: C:
INSTALL.CMD on the driver diskette copies files to the hard drive and starts the
OS/2 Display Driver Install utility DSPINSTL, which prompts the user.
When the Display Driver Install main panel appears, the Primary Display should
indicate Video Graphics Array. If so, click OK and proceed. If VGA is not selected,
select Primary Display and click OK.
Highlight the Driver/Resolution desired and click OK.
When the Source Directory panel appears, choose the floppy drive ( A: ) which
contains the Driver diskette and click on Install.
When the main panel appears again, click on Cancel.
The new driver has been installed. You must shutdown and then re-boot your
system for the changes to take effect.
