Please use win32diskimager if using a windows machine to write image to disk.
In Linux dd is recommended.

Unlike other images I posted this has been created using a virgin install of Mint 19.2 on real hardware.
To apply updates to fresh install open a terminal and use the following, this should not upgrade the kernel.
ISO Image:
No longer available do not ask for access

MD5 Checksum:
No longer available do not ask for access

All issues and support should be directed to this thread.

Downloading............

This failed for me. Made usb stick fine and booted to live disc no problem.

But then is seemed to copy files over ok and got to the end where it said reboot but then the screen flashed to quick to read, but something about kernal not compiled. Then after some time a message came up.

"could not update ICEuthority file /home/cnc/.ICEauthority"

Ok it would be nice if you say when these particular messages pop up.

But I’m guessing on reboot purely on the user name.

The “not compiled” is not an issue unless you are worried about spectre, look it up.

What happens after before the ICEAuthority message and what happens after ?
If you google about this there is a simple fix.
Although I didn’t go through the installation process on real hardware I did on a virtual machine and it went smoothly.
Could you check the md5 sum of the iso ? Google for the procedure if you don’t know how to. We were having electrical storms in our area and I’m on a 4g wireless network for my internet.

Downloaded, used Multisystem, it boots and works on a Lenovo T420S, graphic at 1024X768, sluggish but usable from USB, but the latency is strange, like really strange at 41000 !!! This laptop never does under 300000 no matter what or how or what kernel! Will have to do some more testing, but if that proves to be correct after installation, i owe you a beer or two.
Have to check also the Dell E6510 as it also has terrible latency, even with Ubuntu 10.04 and RTAI, Debian Wheezy RTAI, whatever else i could try, latency=terrible, on both of them.
Later with more useful info, unlike most of the above.

Big thanks really have to go to whoever configured, built and uploaded the kernel. I just put the jigsaw together. Only downside is the Nvidia nouveau driver doesn’t play nice hence the resolution.
But yeah it is a really low latency kernel, really will have to see how it goes on the T60 with docking station as the station has a Parallel Port.

I’m really curious how it would go with XFCE edition of Mint. Could it bring some older 64 bit systems back to being a viable proposition ?
