- ATTACH
The CPU(s) must be attached with the following command:
DS> ATTACH KA820 HUB KAn msiz id
where:
n is different for each CPU (normally, the operator would start
with 0 and increment for each attached processor)
msiz is the size of memory in kbytes <decimal>
Note: If 0 is specified for memory size, the program will
size for memory and print the result in test 25. It will
not result in an error and all available memory found will
still be tested in all memory tests.
id is the CPU node's ID <Hex>
DS> SEL KAn
The SEL must be done for each processor, or simply type SEL ALL.
If external loopback on SLU 1, 2 or 3 is provided, attach each wrapped
SLU as follows:
DS> Attach SLU KAn TCA0 extlp rate ;TCA0 is SLU 1. TCB0 is SLU 2
; and TCC0 is SLU 3
where:
extlp is external loopback provided? (Y or N)
rate is desired baud rate (from 150 to 19200)
Note: Baud rate is not used by EBKAX, so any value can be input.
DS> SEL TCA0 ;or TCB0 or TCC0
- HELP
This program tests portions of the VAX KA820 CPU cluster
hardware which are not specified by the VAX architecture, or
which require manual intervention. This program must run
in a standalone environment under control of the Diagnostic
Supervisor.
Type HELP EBKAX ATTACH for attach details.
- SECTIONS
By default, all tests are run except the manual intervention tests,
the RX50 full read/write test and the longer moving inversion memory
test (sections MANUAL, RX50 and MEMORY).
- Manual
Runs tests 4 through 20, and 44 which are tests requiring operator
intervention.
- Memory
Runs tests 25 through 31, which does a more extensive Moving Inversion Memory
test in addition to the default memory tests.
This section will take several minutes to run per memory module.
- RX50
Runs test 39 on drive 0 and/or drive 1 depending on the setting of EV 3
and EV 4. This test writes and reads every sector of a scratch floppy
inserted in the drive. This test will take about 6 minutes to run per
drive.
- DEVICE
The diagnostic supports the following devices:
One or more VAX KA820 CPU(s)
Note: Use the B node command to run on attached processors. e.g. B 9
will boot attached processor at BI Node 9. When this diagnostic is run,
the attached processor will be tested.
Type EXIT to return to primary processor.
Dual RCX50 drive (Optional KA820 Console Load Device)
3 onboard SLU's (1, 2, and 3). SLU0 is normally used for the Console
Terminal.
- EVENT
Event flag 1 allows reporting of all SBE's as hard errors, which identifies
which RAM chip is causing a Single Bit Error.
Event flag 2 turns cache on for memory tests to speed up execution.
Event flags 3 and 4 specify scratch disks in the console RX50 floppy 0 and 1
respectively (set indicates that a scratch disk is loaded). This is for
use on an 8200/8300 system.
- QUICK
Setting the quick flag turns cache on for memory tests and skips the
unaligned memory test (test 28). Execution time with 2 megabytes of memory,
no SLU external wrap, and no scratch disks is under 60 seconds with this
flag set.
