Hi Glen,
many thanks.
Problem was, that I had no clue, how to bypass the error to enter the setup mode. As Ctrl
C was not working.
I have in the meantime found in the KDJ11-D/S dokumentation, that (CTRL + O) (4)
Enter" do it.
Now I have set all setup parameters to the same as on the working KDJ11-B and it boots up
without errors.
Here my parms:
Type a command then press the RETURN key: 2
List/change parameters in the Setup table
A - ANSI Video terminal (1) 0=No, 1=Yes = 1
B - Power up 0=Dialog, (1)=Automatic, 2=ODT, 3=24 = 1
C - Restart 0=Dialog, (1)=Automatic, 2=ODT, 3=24 = 1
D - Ignore battery 0=No, 1=Yes = 0
E - PMG 0-(7) 1=.4us, 2=.8, 3=1.6, 4=3.2,...7=25.6 = 7
F - Disable clock CSR 0=No, 1=Yes = 0
G - Force clock interrupts 0=No, 1=Yes = 0
H - Clock 0=Power supply, 1=50Hz, 2=60Hz, 3=800Hz = 1
I - Enable ECC test (1) 0=No, 1=Yes = 1
J - Disable long memory test 0=No, 1=Yes = 0
K - Disable ROM 0=No, 1=Dis 165, 2=Dis 173, 3=Both = 0
L - Enable trap on Halt 0=No, 1=Yes = 0
M - Allow alternate boot block 0=No, 1=Yes = 1
N - Disable Setup mode 0=No, 1=Yes = 0
O - Disable all testing 0=No, 1=Yes = 0
P - Enable Unibus memory test (1) 0=No, 1=Yes = 0
Q - Disable UBA ROM 0=No, 1=Yes = 0
R - Enable UBA cache (1) 0=No, 1=Yes = 1
S - Enable 18 Bit mode 0=No, 1=Yes = 0
The trick was Parm "H" which was set to "0".
Many Greetings
Ulrich

If you have one M8190 KDJ11-B which works fine and another one which
has this error when swapped into the same system you should check the
EEPROM configuration options between the two and see if the LTC
options are configured differently between the two.

2.3 EEPROM CONFIGURATION PARAMETERS
Table 2-6 Configuration Parameters
H - Disable clock CSR (0)=No (1)=Yes
I - Force clock interrupts (0)=No (1)=Yes
J - Clock frequency (0)=Power supply (1)=50Hz (2)=60Hz (3)=800Hz
If the LTC parameters are configured differently between the two try
changing the parameters of the non working one to match the parameters
of the working one.
