reboot again, all working...
again error after reboot...
reboot, normal boot...
again error after reboot...
reboot, normal boot...
...why it happens?

are you using an USB connected external cardreader?

yes
pc>usb hub>sd card reader

Hi @deepforest

share your menu.lst so we can help you...

I use the same type of installation
sdcard formatted to ext4 with usb adapter using grub4dos

This is mine, I hope it serves as an example for you.

title Puppy fossapup64 9.6 (sdc1/F96-CE_4)
find --set-root --ignore-floppies --ignore-cd /F96-CE_4/initrd.gz
kernel /F96-CE_4/vmlinuz psubdir=/F96-CE_4 pmedia=usbhd pfix=nocopy
initrd /F96-CE_4/initrd.gz

maybe this can help

Cheers!

Change in the entry the pmedia=cd to pmedia=usbflash

See if that helps?

@deepforest :-

Yup, I concur with my colleague. Either pmedia=usbflash OR pmedia=usbhd (as given by PipzDex, above) should work. These will tell the bootloader exactly what type of install to look for.....and crucially with USB, it allows those extra few seconds to get things detected.

I'm beginning to think myself that the pmedia=cd statement is perhaps getting long in the tooth, and in need of finally being retired.......especially given that not many machines come with an optical drive any more. For most Linux users, USB is now the preferred interface for either trying-out OR installing from/to. Either way, Puppy - to the best of my knowledge - remains the only distro I know of that, uniquely, can still 'save' a session back to the very same CD/DVD that it was loaded from.......provided the disc was burnt (and left) in the 'open' condition.

pmedia=usbflash, working for sd reader but booting to default session with no my saved session restoration,
i am now also make frugal installation at hdd, puppy

only if the settings in @deepforest 's menu.lst are correct, which most likely they are not (see the listing he posted).

The reason why pmedia=cd works better for him lies in the questionable "feature" of this parameter to scan all HD partitions for a suitable savefile or even main sfs. If found Puppy would load them, giving them preference, essentially ignoring files that exist on the boot device. It assumes that the user appreciates the much faster loading time compared to loading from a slow CD. In @deepforest's case this "feature" seems to work as a crude error correction by ignoring insuffienct grub4dos settings

@MochiMoppel :-

Mochi, is there actually a list of 'definitions', tucked-away somewhere, for all these boot parameters? And if so, where would I find it?

Cheers.

pmedia=cd means "search all partitions", while pmedia=usbwhatever means "only search USB devices". The former is a superset of the latter, but the latter also activates PUPMODE 13.

pmedia=usbflash, working for sd reader but booting to default session with no my saved session restoration,
save session to local hdd, sdd3

Copy this save to the SD card install.
Same location as the Puppy SFS files.
Have the same save at both locations.

Then the booting with the SD card, should find and use it.

The pmedia=usbflash is telling the boot process to only look on the USB device for the files.

pmedia=cd for booting from a USB does not work.
Because it is telling the boot process that the Puppy OS files should be on a CD/DVD and not on some other external device.
But it does tell it to look on other internal drive devices, for the save. Which also lets it see the Puppy OS stuff, on internal drives, during the search.
Booting from a CD/DVD, is most likely going to have to put the save, on some other drive.

Booting from USB and looking for the save on another device, is getting into the very,very newest versions of Puppy.
But it is still in testing, to make sure it will always work.

Best thing to do, is always have the save file/folder on the same drive, as the Puppy install.
At the same location, on the drive, as the Puppy OS SFS files.

also every time if i rebooting from sd reader session to frugal hdd session i have error, but afeter reboot all booting normally

First you are assuming all the hardware in this computer is working 100% perfect all the time.

Rebooting does not totally make sure everything in RAM is totally removed.
Assuming it is, may or may not be true all the time, or some of the time.

So, the best way to change to a different operating system, is to do a total OS shutdown and power off.

Wait one minute.
(totally makes sure nothing is still in RAM or partially still in it)

Then do a power on boot up, of some other operating system.

Plus a complete power on boot up, forces the computers bios to do a complete new, power up of the hardware.

Yes, I have seen this work as fix for strange issues, if all I did was just reboot into something else, without first doing a power off, wait 1 minute, and power on boot up.

Thanks, Peter. I had vague memories of something in the Wikka, years ago, but this is even more comprehensive that what I remembered... And it shows I don't read everything that gets posted here; even old dogs CAN learn new tricks!

Cheers.
