I had no problems with booting and running my copies of Tiny Core Linux 12.1. This was in Legacy mode.
As I've noted before the onboard embedded flash appears as /dev/mmcblk0
One strange thing I noted was in the report of the available memory in the 32-bit kernel case.
The figures I saw in the dmesg
output were:
32-bit kernel Memory: 1644384K/1680000K available 64-bit kernel Memory: 3616600K/3777152K available
With 4GB of RAM fitted I would expect the available memory in the 64-bit case to be down by the amount of RAM put aside for the display memory - perhaps 256MB or 512MB. In the 32-bit case (and a non-PAE kernel) You have the 4GB address limit so you need to add in the chunk of memory reserved for the PCI address space as this overlays some of the 4GB of RAM. This normally drops the available RAM by maybe 1GB? I've never seen 2.5GB vanish before.
Subsequently, for a short term project, I tried Linux Mint (linuxmint-20.2-xfce-64bit.iso
)
and Ubuntu (ubuntu-20.04.3-desktop-amd64.iso
). I started off with Linux Mint but had similar problems
to those that others had with running debian on the HP t620.
It installed OK but then there were issues with getting it to boot the installation.
Rather than spend time on this I switched and tried out ubuntu. This installed and ran without any problems.
