Building Another Logger
MTCAT:
Hi Rich,
Thanks for the help with the images and code insertions, will give that a try.
With the help of Gparted on my Slackware desktop, I was able to delete the swap partition (sda1) but even with doing that, before I could resize sda5, I had to expand the "extended" partition sda2 to it's largest possible size of ~ 120 GB, after doing that, it was no problem to expand sda5 as well and now I have sda5 as ~ 120 GB, so that should be good now.
Thanks,
David

Hi Rich,
As seen in the image below, there's a symbolic link which connects /home/tc/data to /mnt/sda5/data.
With Lubuntu fired up, do you think it would be correct to simply make a directory called data in the uppermost directory level on the CF-card? (as regular user in Lubuntu), just trying to prepare the playing field ahead of time as much as possible for TinyCore.
Thanks,
David

If you want to do this using Lubuntu, you should probably do something like this:
--- Code: ---mount TinycoreStorageDevice
cd TinycoreStorageDevice/home/tc/
ln -s /mnt/sda5/data data
chown 1001:50 data
--- End code ---
This assumes /mnt/sda5/data is still correct for the new system.
I'm not familiar with Lubuntu, so you may have to perform some
of those commands as root or using sudo.

A DOS partition table only has space for 4 primary partitions.
If you want more than 4 partitions, you need one of those
partitions to be created as an extended partition.
An extended partition acts as a container for multiple logical
partitions. One of my machines has 12 partitions on its drive.
Since the extended partition is a container, you can't make
the logical partitions inside it larger than the container. That
is why you had to expand the extended partition first.
Since you use gparted, you will see choices of Primary, Logical, and
Extended when creating partitions on a device.

Hi Rich,
Oh, okay, thanks for the explanation of what the extended partition is, didn't know that.
Bad news is, I think I wrecked my main backup pen drive with all the thrashing in the BIOS, I was having issues with the Quick Boot and Enhanced Boot and POST tests where it seemed that sometimes the pen drive would get completely missed and would end up booting in Lubuntu even, and other times, would hang halfway through booting TC (like before loading extensions even), and other times would hang at the vesamenu screen (to select regular or real time TC) after the 10 second count-down was complete (would hang at second 1), so with all this thrashing many times I couldn't shut down the computer properly, and I think it finally "bit" me.
Image below shows what I get now when I try to boot with my "primary" backup pen drive, I get an "input/output" error from /opt/bootsync.sh, I even went into /opt and tried to look inside bootlocal.sh, and some of the other scripts (with cat, and tail), and also got an "input/output" error. Also, my home directory, /home/tc is completely empty.

Luckily I have a second, almost complete backup pen drive, it's only missing the digitemp temperature sensor software. So that seems to be running okay and I think I'm done hacking on the BIOS now, it seems to be working okay, hopefully?, using the same settings as in the BASE and with the updated video BIOS for the PixelQi screen.
So I think I'm going to pull apart my BASE receiver anyway, and make about 6 copies of its boot pen drive, and can then also change out the U-Blox CMOS battery since that one has been in there for a couple of years already.
Thanks,
David
