has anybody installed slackware on a lenovo T480?

cI recently bought a Lenovo T480s laptop. I plan on installing
slackware 15 when it's going to be released.
I used the contents of the usb.img on a thumb drive to get
rid of windows 10 and repartitioned the disk with fdisk.
My first surprise was
Code:fdisk -l /dev/sdadidn't work. Then I finally figured the (solid state) hard drive
device name was nvme0n1
Next stage, I tried to use the latest (2021-09-08) slackware live
(the xfce variety) installed on an external USB hard drive:
I copied the files from the extracted iso and added an entry
in an existing menu on the (syslinux) bootable drive.
I got a kernel panic message.
I tried porteus and was able to access to it. But it lacks
some tools (grub, etc.).
I tried systemrescuedisk. It boots ok but it can't find the partition of
the root filesystem... I'm still working on it.
I have a couple of questions?
Does anybody know of a small console-based linux live system
with tools such as grub (I prefer legacy, but grub2 would do)
recent enough?
Has anybody successfully installed slackware?
