Subject description: Replace BionicPup64 kernel to Tahrpup64
 

My internal SD card reader does not work with BionicPup64 kernel (installed frugal to HD), but it does work with Tahrpup64 kernel.
as pictured, I open iso file of Tahrpup64 and place vmlinz on the top slot and BionicPup64 zdrv_bionicpup64_8.0.sfs on the bottom, and reboot.
after reboot uname -r command shows the original BP64 kernel (4.19.23). Kernel did not change and SD card does not work.

what am I doing wrong here?

thanks

That info on that page is misleading for the bottom slot.
The slots take the files from the new kernel source.

Quote:
I open iso file of Tahrpup64

Drag and drop the vmlinuz in the Tahrpup64 iso and place it in the top slot.
Drop the tahrpup64 zdrv sfs in the bottom slot.

The kernels button, at the bottom, will take you to the web page, where all the kernel packages, for most Puppy versions, are stored.
You can also get the needed files from them.

Whatever name the file you use from the new kernel source.
This program will correctly name them in the frugal install you are changing kernel.
Should also make backups of the files you replace.

thanks for the instructions, I placed correct files (from Tharpup64.iso) as shown on both top and bottom slots and rebooted, but the kernel did not change. Still 4.19.23 (BP64)... no SD card recognition...

Change kernel program is already in Bionicpup64 8.0
Quickpet->Info->Change kernel

I did already run Quickpet->Info->Bionicpup updates


Worked OK for me.

you did click on OK?
Got a message that change was made and backups of changed files?

Can you post an image of what is in the location of all the Bionicpup64 8.0 files.

try the simple manual method of changing the Bionic 4.19.23 kernel with the Tahr kernel. First ensure you are using the correct 64 or 32 bit version.

in the Bionic directory rename the vmlinuz and zdrv_upupbb_18.05.sfs to something like vmlinuz-4.19.23 and zdrv_upupbb_18.05.sfs-4.19.23

then copy the vmlinz and zdrv_upupbb_18.05.sfs from the Tahr directory or from the Tahr ISO and paste them into the Bionic directory then reboot into Bionic

This should work ok

PostPosted: Wed 29 Jan 2020, 16:07    Post subject: my mistake  

I have found I was not able to change the kernel since my PC was not installed to HD, only had sav folder on a HD partition. I was booting from a USB stick.
I appreciate the help but I will take it from here to get my internal SD reader working by changing the kernel. Sorry about my mistake.

It still should have worked as long as vmlinuz and the zdrv are on the USB stick.

The image you posted shows no vmlinuz on the location of the zdrv.
Also, I see no backups that should have been made.
Is that image what is on the USB stick?

I assume there is free space on the USB stick that will hold changes and added files?

image is wrong, not the USB stick. I was able to change the kernel per your and rockedge suggestions but ran into nvidia driver issue..., giving it all up for now...

01micko,

This is a very good program, but there is some confusion, with the information on the programs, main window.

It is not clear, to a lot of people, that only stuff from the new kernel package, goes into the input slots.

The info for the bottom input slot is confusing.
Could you change it to just say:
New kernels zdrv sfs or kernel modules sfs if built with kernel-kit.

Maybe a statement at the top, that all inputs are from the new replacement kernel package.

Yes I was just thinking that yesterday when I used it in fossapup.

I'll fix it in woof something like zdrv_xxx_xxx.sfs maybe?

Ok, done in woof.

One other issue with change kernels - 64bit libau kernel kit files in slacko derivatives go in /usr/lib64, whereas those for ubuntu derivatives go in /usr/lib with /usr/lib64 as a symlink. That's why I specify which flavour each kernel is.

01micko,

Thanks for the change. Very Happy

I know I am being a pain in the a@#s.

You would not believe how many times I had to tell someone this:
That all inputs are from the new replacement kernel package.

Maybe add as a statement at the top.

I have been working on a Chromebook I have. Turning it into a Puppy laptop.
This change kernel GUI is getting well used, trying out different kernels.

Thanks!
