Last post by Grunchy - March 31, 2024, 17:22:13 PM
Laptop is from 2002 or so, 512MB ram, 149GB PATA. I consider it the perfect DOS/Win9x/WinXP machine & even works well with Linux.

My plan is to multi-boot "Dos6 + Win3.1" from primary 1 (2GB), "Win95" from primary 2 (10GB), "Win98" from primary 3 (10GB), "Kolibri OS" from logical 1 (2GB), "WinXP" from logical 2 (40GB), "Lubuntu 16.04" from logical 3 (83GB + 2GB swap).

Plop V5 working with Linux doesn't make any sense to me. We have this warning, "Warning Linux users: Install LILO or GRUB to the boot sector of your Linux instead of the Master Boot Record (MBR). The Plop Boot Manager is not a Linux loader and cannot start Linux without LILO, GRUB, Syslinux and similar!  See Linux Boot Managers."

And of course if you click "Linux Boot Managers" all you get is a cryptic message, "LILO, GRUB / grub4dos, GRUB2: I had no time to write some short descriptions how to install them to the boot sector."   <-- I DIDN'T FIND THIS INFO VERY USEFUL TO ME.


Well the laptop did work with Plop V5 (for DOS and Win9x), though I could never figure out how to boot Linux/Lubuntu with it.


So then I thought, perhaps I can boot Linux with PBM6? But when I try to boot up PBM6 from floppy disk it comes to a screen and "freezes" (no response from keyboard or mouse).

It says:

Hard disk     [IDE, PM, P1] >
CD/DVD drive  [IDE, SM] >
Floppy drive  [FDC, 1] >

Viewer, File Commander
Setup
About
Shutdown

This is the 12/02/2024 version, I also tried the latest "pbm6-20240301.zip" and got the same result.

Maybe I don't need such a fancy bootloader as PBM6, perhaps Plop V5 is good enough for this older Laptop.
But then, is there any possible way to write an instruction or perhaps sequence of events for configuring Plop to work with Linux?

One imagines someone at some time was able to achieve this, perhaps a "how to do it" for the next guy.

How crazy is to boot an encrypted ubuntu in a tiny usb 3 drive plugged into a cheap expresscard?

And the best thing is the expresscard adds no volume to the laptop.

Thank you!!

Now, I have an ancient desktop PC, I think I can upgrade it with a usb 3.0 ports card.

I wonder if...  ;D

There is no "/boot" folder in the ext4 partition, I had to make one to put the plopkexec.cfg file in.


For your encrypted system use this plopkexec.cfg
label Ubuntu - Encrypted
kernel /vmlinuz
append root=/dev/mapper/vgubuntu-root ro quiet splash
initrd /initrd.img

Write this plopkexec.cfg file into the same directory as vmlinuz is. You will see there also files like vmlinuz-6.5.0-18-generic and so on. vmlinuz is just a symlink to the latest kernel.

Wow, that worked in a regular ubuntu installation!, boots much faster, it was /dev/sdd2.
Thank you!

However I'm now trying to boot an encrypted installation, with no luck.

The regular ubuntu installation has two partitions, a small FAT partition and a big ext4 partition, I put the plopkexec.cfg file in the ext4 partition, "/boot" folder where the files vmlinuz and initrd.img can be found.

The encrypted installation, has three partitions, the same as above and a third encrypted partition.
There is no "/boot" folder in the ext4 partition, I had to make one to put the plopkexec.cfg file in.

The files vmlinuz and initrd.img are in the "/" folder instead. I changed the plopkexec.cfg file accordingly and the ubuntu installation is detected by plopkexec, and it starts to boot but it doesn't boot correctly, it asks the password in a different way and then it gives some errors and ends up in a "busybox" shell asking for commands.

When booting normally in a usb 2.0 port, whatever I put in the ext4 "/" folder, will appear in the "/boot" folder of "computer".

Hello,

Quote from: fasterubuntu on February 18, 2024, 22:20:21 PMIs there any way to make it boot anything or at least an already installed ubuntu?

Yes.

On your Ubuntu installation create the file /boot/plopkexec.cfg
label Ubuntu - Hard disk
kernel /boot/vmlinuz
append root=/dev/sda3
initrd /boot/initrd.img

Maybe you have to change the 'append' line and change /dev/sda3 to your Ubuntu partition.


PlopKexec will find this configuration file and you can boot Ubuntu.

Hi there.

I like installing ubuntu on usb drives.

My laptop has usb 2.0 ports only. I bought an expresscard that gives my laptop two usb 3.0 ports. It is fantastic and works very well, except I can't boot from these usb 3.0 ports.

I've been experimenting with plop software and...

Plop boot manager 5 doesn't seem to be useful.
Plop boot manager 6 freezes.
Plopkexec works!! , it blew my mind, unfortunately I can boot only ubuntu/lubuntu usb installers.
It doesn't recognize usb drives with ubuntu already installed.

Is there any way to make it boot anything or at least an already installed ubuntu?

I'm not a linux wizard.


Thank you.

Hello SelfRef,

please try this floppy image. I rewrote the loader.

Last post by SelfRef - February 04, 2024, 16:50:12 PM
Hi, I noticed the latest version of PBM6 (pbm6-20230818.zip) contains non-working floppy image (pbm6.img). On either Qemu or real hardware it just doesn't boot without any error. On real hardware floppy drive is active for a while then nothing happens.

For the comparison, the previous version (pbm6-test-20221118.zip) doesn't have this issue and works just fine.
