BRAVO 486/33 AND PIXEL WORKS RA-1280
PROBLEM: When using the AST Bravo II 486/33 with the Pixel Works RA-
1280 graphics board installed, the diagnostic software bundled
with the RA-1280 may hang when running board tests, requiring
a cold boot to restart the system.
CAUSE: The RA-1280 is a bus-mastering card that is not compatible
with the Premium II, Premium CLEM, and Bravo II 486 series of
computers.
AFFECTED
SYSTEMS: AST Premium II systems.
AST Premium CLEM systems.
AST Bravo II 486 systems.
SOLUTION: AST Sustaining Engineering has determined that this problem
will not be fixed. AST suggests using an alternate graphics
adapter.
