Specifications

11.2.11 Test 20: Universe NMI Test
This BIST checks the ability of the universe to generate a NMI to the processor using the
software generated interrupt via LINT1.
Error codes:
0406h - no interrupt generated or spurious interrupt
11.2.12 Test 22: RAM Data and Address Bus Test
This BIST checks RAMs data and address bus.
First part of the BIST checks data bus wiring for each memory row in specified memory range. It
tests each bit of data bus with walking ones and zeros.
Second part of BIST checks address bus wiring.
Default memory range is from 1 Mbyte to the top of fitted memory.
Error codes:
0401h - Error on data bus
0402h - Error on address bus
0403h - Memory was not filled with zeros
11.2.13 Test 23: Local RAM Read/Write Test
This BIST is a simple non-destructive read-complement-write test. The range of memory to be
tested depends upon the test handler from which the BIST was invoked.
When the test is executed from the slave test handler, e.g. during soak testing, the test range is
limited to 64 Mbytes; however, each time the BIST is executed it tests a different block.
Therefore, over the duration of a soak-test run the whole of memory will be tested a number of
times, but the overall test coverage will be improved for large memory capacity boards.
When the test is executed from the master test handler, the test range is from 1 Mbyte to the top
of fitted memory. However, BIST parameters can be used to specify a different test range. Note
that the video memory hole between A0000h and BFFFFh must be avoided.
The test operates on double words throughout the range selected. During the test, PCI Bus Error
interrupts are enabled. If one of these should occur the test is aborted and a diagnostic message
displayed.
To reduce execution time this BIST runs from DRAM; however, the area of memory from which
the test code executes is first tested by the ROM-based version of the routine.
Error codes:
0300h - Test failed. For details see accompanying message
0402h - PCI bus error occurred
0403h - PSB Error occurred
