- AST RAMPAGE/EGA for AT AND PREMIUM 286
-
-
-
- The AST Rampage/EGA for AT does not operate correctly in systems
- that utilize the Chips and Technologies 80286 processor set. This
- includes the AST Premium 286 system.
-
- An incompatiblity exists in the way that the video section of the
- Rampage/EGA for AT board is accessed by this particular 80286
- processor. One of the timing signals used by the processor is not
- recognized by the Rampage/EGA video circuitry.
-
- The symptom is that the machine will sound one long and three
- short beeps and fail to boot.
-
- The AST Rampage/EGA for AT works in systems not based on the
- Chips and Technologies processor.
