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.
