VGA PLUS - IRQ 2 CONFLICTS
|
|
|
|
|
|
The VGA Plus adapter, part number 202262-003 revisions A or B, causes a
|
|
conflict with other adapters in the computer that requires the use of IRQ 2.
|
|
Such adapters include the IBM 3270 emulation adapter, or networking adapters
|
|
which may be configured to use IRQ 2.
|
|
|
|
This conflict is due to the VGA Plus seizing IRQ 2 on the system bus and
|
|
preventing any other adapter from utilizing this signal.
|
|
|
|
To resolve this incompatibility, replace this VGA Plus adapter with one that
|
|
carries the part number 202262-003 revision C (or above).
