IBM PC300GL - Video corruption in OS/2 with magnetic stripe reader
Applicable to: World-Wide
Symptom :
IBM PC 300GL Series 6272 & 6282 systems may exhibit the following symptoms in OS/2 3.x or 4.x with Cirrus video drivers and the IBM 4777/4778 Magnetic Stripe Reader drivers installed:
A. OS/2 WARP 3.x intermittently fails to boot. When the system does successfully IPL, operation is erratic. An OS/2 Full Screen may take up to a minute to display.
B. OS/2 WARP 4.x boots consistently, however, opening an OS/2 Full Screen takes approximately a minute to display.
C. In 800x600 resolution, switching from a DOS Full Screen to the Desktop and back to the DOS Full Screen causes video corruption.
Problem Isolation Aids :
The failure does not occur when using the native OS/2 VGA device drivers.
Fix :
Use the "/X" parameter (do not report error messages) when installing the 4777/4778 drivers in the OS/2 CONFIG.SYS file. This parameter will allow OS/2 to boot consistently, however, the OS/2 Full Screen in OS/2 WARP v4.0 will be displayed as a window.
To eliminate the failure on both versions of OS/2, use the native OS/2 VGA drivers in place of the Cirrus video device drivers.
This problem is still being investigated. This tip will be updated with additional information as it becomes available.
