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.
