============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0701 08-07-91 ============================================================================= PREMIUM EXEC SERIAL MOUSE/BACKLIGHT TIMEOUT When the "Mouse Connected to.." field is set for "Serial Mouse" in the Premium Exec CMOS setup, the Backlight Timeout feature will function correctly only if a mouse driver is installed in the CONFIG.SYS or AUTOEXEC.BAT file. This anomaly is caused by a Hardware/Software Interrupt conflict that occurs when the Serial Mouse field is set and no mouse driver is installed. To correct this problem, install the correct mouse driver in your CONFIG.SYS file or execute the correct mouse driver command either at the DOS prompt or in the AUTOEXEC.BAT file.
