AST RESEARCH TECHNICAL BULLETIN TB-0191 6-24-86
|
|
|
|
|
|
RAMPAGE AT/8 MHz
|
|
|
|
|
|
It has been determined that the original version of the AST
|
|
Rampage AT board will not operate consistently in the IBM Model
|
|
339 AT (8 Mhz clock speed). This condition has been verified by
|
|
AST Research.
|
|
|
|
What may happen with this board installed in the Model 339 AT is
|
|
that either the REMM.SYS program will not recognize any Rampage
|
|
AT memory, or "Parity errors" will be generated when attempting
|
|
to address the memory.
|
|
|
|
These boards can be identified by their revision level. This
|
|
number can be found on the back (solder side) of the board,
|
|
etched along the edge of the board that is opposite the mounting
|
|
bracket. Any board with one of the following numbers should be
|
|
considered suspect:
|
|
|
|
202079 - 301 -A, -B, or -C
|
|
202079 - 302 -A
|
|
|
|
These customers should contact AST Research to have their
|
|
Rampage AT exchanged for a later revision.
|
|
|
|
If the revision level is the following (or above) the board will
|
|
operate in the Model 339 AT:
|
|
|
|
202079 - 302 -C
|
