Multiple BOB's and parallel ports, and different driver card issues

IF only ONE board is installed, the port not found error may pop up once at some point, then never again. Wtih TWO boards installed, it always pops up right when I load the GUI and crashes the GUI load.

Assuming that the error box pops up, can you click the "select all" button, then Ctrl-C and paste the error listing to a text file and attach it here.

What "loadrt" line are you using when attempting to start both cards?

can we see here your HAL and ini file of the mashine
also pleas can you tell us here what general system did you setup

and where did you get it from
on a standard parport base period shoudt be 100k this leads into a 60k step per second no stepper will meet that so you got lots of time and no following error

Attached are the files I've been working with.
my-mill.hal is the setup for TWO parallel ports which won't load due to real time timeout and port not found errors.
my-mill 1port workfing.hal is the variant the seems to work A-OK.
my-mill.ini works with either .HAL file.

LinuxCNC was downloaded from the LinuxCNC site at the ADM64-Stretch-R13 version, on the recommendations of the forum. The computer is a Dell desktop. 64 bit, 8G memory, ~1.9Ghz. The parallel port cards are SIIG Legacy PCIe. ECP/EPP/SPP.

What model of Dell desktop ?
