Still boots 3.4.9 like it should. Give up, wondering if the low memory msgs is telling me the cpu cache is dead? So I give up there and continue with the new build. write a 5i25-7i76-x2.bit to the 5i25.powerdown reboot, power up and verify it, good. The 7i76 with the same dble male cable I've used for yonks, even try 2 more off the wall cables, both leds on the 7i76 are lit. w1, w2 right hand position because I've a 5 volt hooked up for the logic stuffs, and an isolated 15 volt supply on the field power hookups. But the leds are lit normally. But nothing in dmesg indicates sserial is running, and the exit message when I try to run linuxcnc -l makes no sense.
Its as if the hal file has no linkage back to the ini file to get setp stuff of the [JOINT_0]SCALE values for a setp stepgen.0.position-scale. And my logins are crippled, can't highlight slide a copy/paste, mouse clicks comeout as data echo's on the command line. Started another terminal, logged into it now I can copy/paste gene@shop:~$ linuxcnc -l LINUXCNC - 2.8.0-pre1-4590-g584314c Machine configuration directory is '/home/gene/linuxcnc/configs/6040-5i25-7i76' Machine configuration file is '6040-5i25-7i76.ini' Starting LinuxCNC... . Found file(REL): ./6040-5i25-7i76.hal ./6040-5i25-7i76.hal:107: parameter or pin 'stepgen.0.position-scale' not found Shutting down and cleaning up LinuxCNC... line 107 of that hal: setp stepgen.0.position-scale [JOINT_0]SCALE It exists in the ini file. So something is fubar. memtest86 won't run from grub, claims low memory is too small, crashes and reboots to grub in 4 secs or so. dmesg looks pretty normal. Except no hint of the 7i76's presence can be detected.

Turned into the next days project. Legs/feet played out last night. And I haven't really learned much. I jacked the cards up a half inch so the power supplies would fit under the cards with 1/4" to spare & hooked up the power supplies. Not much use doing anything else till the cards talk to me. And the 7i76 is muted. Just prowling the net. looking for someplace to src a couple sticks of memory for one of these intel D525MW atom motherboards, and all the usual businesses have dried up, not willing to talk to a customer unless you have a business account with them. What I want is a couple 2Gb sticks of dimm, only 800 mhz so both slow and old, lappy style, to fit the above motherboard. Where are you folks getting your stuff these days? Thanks all.
