Porteus 4.0 and a NVMe drive

What's needed to boot the 4.0 ISO on a NVMe SSD drive on a new Dell notebook. The ISO boots fine on the old SATA SSD drive on my old Dell. The problem is it doesn't find the porteus .cfg file when booting. Using the same approach Porteus 5.0 ISO boots fine.

My grub2 menus.

Code: Select all

menuentry " Porteus 5.0rc3 ISO - AF+"  --class slackware   --class icon-porteus  {

     set bootparms="volume=33 reboot=cold extramod=$linux_folder/Modules;$linux_folder/rc3Modules noload=kde;jinn;lxqt;xfce;lxde;mate;open;mychanges;menu3" 

     search -f $iso --set=root
     loopback loop $iso
     linux (loop)/boot/syslinux/vmlinuz from=$iso $bootparms
     initrd (loop)/boot/syslinux/initrd.xz
     }

Code: Select all

menuentry " Porteus 4.0 ISO - AF+" --class slackware   --class icon-porteus  {

     set boot_parms="volume=33 reboot=cold $extramods$linux_folder/Modules noload=cinnamon"

     search -f $iso --set=root
     loopback loop $iso
     linux  (loop)/boot/syslinux/vmlinuz from=$iso $boot_parms
     initrd (loop)/boot/syslinux/initrd.xz
     }
Do I need a different initrd.xz or a different vmlinuz?

It would be nice to boot Porteus 4.0 without having to pull out my old Dell. :)

Use a kernel that supports booting on nvme

hi Ed_P this is ok? from=$iso $boot_parms the porteus4 boot line and this is the porteus5 boot line from=$iso $bootparms maybe is not

Ed_P,

Rename vmlinuz and initrd.xz in porteus-4.0 ISO, and copy same from porteus-5.0-rc3 ISO. copy *.cfg file also to porteus folder and try. Most probably you will succeed.

Assuming both ISOs remain in different partitions & in root.

Actually I've tried 2 that I use with Porteus 5.0. Neither works.

Code: Select all

Porteus-CINNAMON-v4.0-x86_64-5.16.11.iso*
Porteus-CINNAMON-v4.0-x86_64-5.16.15.iso*

Yea, they're ok, just user created names given to a variable.

Oh raja I think you've nailed the problem. The nucleus files that I copied to the 4.0 ISO are created on my 5.0 system and from the 5.0 ISO and the *.cfg files are most likely named porteus-v5.0*. :o Thank you raja. :beer:

Well, I tried renaming the /porteus/porteus-v5.0*.cfg file and that didn't help. :o :wall:
I should have tried tome's cfgfile= cheatcode idea.

Ok. Are you referring to the one from my Porteus 5.0 ISO? The kernel I'm using with Porteus 5.0 is created by fulalas's Simple Kernel Script and it only creates 000-nucleus.xzm, vmlinuz and 06-crippled-sources*.xzm files. No initrd file.

hi Ed_P we have to know the steps for the boot of the iso, the file system that hosting the iso maybe the initrd do not have the nvme driver inside,but i can go wrong on this....

The ISO files are on a Windows NTFS partition along with many Modules and save.dat files used by the Porteus systems. This arrangement has worked for years on a Acer notebook and an older Dell notebook. The ISOs are booted when I boot the computer and get a grub2 menu system that allows me to select which and how to boot the ISOs.

The same configurations and layouts were copied 3 months ago to a new Dell notebook I received and that's when the problems started. The new Dell has a HVMe harddrive. Actually it's an SSD drive, and my old Dell had a SSD drive also and it is a SATA system. And both Dell's have Windows 10 systems driving them.

When booting the ISOs all booting starts within the ISO via the grub2 loopback linux (loop) and initrd (loop) functions.

Neither cfgfile=porteus-v5.0-x86_64.cfg nor cfgfile=porteus-v4.0-x86_64.cfg worked with Porteus-CINNAMON-v4.0-x86_64-5.16.15.iso. :(

hi Ed_P take the porteus 5 initrd.xz and use it to porteus 4 mount the iso and change the inirtd.xz from porteus 5 to porteus 4 the initrd seem that have a different way to manage ntfs partition,btw i am not shure for this but that worth a try,don't change the vmlinuz that is kernel related only the initrd.xz

It's quite possible the porteus 4 init.xz is the same one.

The one in 5.0 is not new. I'll boot the old Dell and bring up 4.0 and see what it's using.

Such old, old dates.

But the initrd.xz does proceed the one in 5.0. :happy62:

If Porteus 5.0 can boot on nvme then you can use initrd.xz, vmlinuz and 000-kernel.xzm from 5.0 to 4.0
