The Question is:
I have computer Digital AlphStation 255 Family
how can I bypass cache memory by using jumpers?
The Answer is :
There is no cache-disable jumper on the AlphaStation 255 series.
The AlphaStation 255 series has a 32 kilobyte primary cache, and a
one megabyte secondary cache. The DECchip 21071-AA (APECS) chipset
provides the cache and memory interface (and a PCI bus adapter).
It would appear the system has a hardware error. For maintenance and
diagnostics, please contact your hardware support organization or
contact the Compaq Assisted Services (see the OpenVMS FAQ) group for
assistance with self-maintenance.
