Recognition point in time of G4D partition?

[JASpup]

Odd scenario: by design an old 32 laptop boots by USB or internal HD but not by SD card.

HD is in a failing read-only state so I am experimenting.

I am trying to boot the SD card by USBFLASH. I've both created a manual boot menu as well as automated G4D (they look similar). The menu is on USB, and while USB distros boot, the SD output is the following:

Code: Select all

Error 22: No such partition. 

Is the problem that in a boot state the system cannot read an SD card despite having a UUID for it?

@JASpup :-

It's more likely that the BIOS in that machine simply isn't written to recognise the SD card as a boot device. Such also requires chipset support for it to be fully-functional.

SD cards are almost always capable of being written-to-/read from, but booting requires some other stuff which has to be supported by the machine's motherboard chipsets......that, and a compatible BIOS, of course. Without these, it's a complete "no-go".

I have an SD card reader in this new HP desktop. I also have a 'minimal' Slacko 560 on a 2 GB SD card. It won't boot from the SD card slot, so I simply use a USB to SD card adapter that I bought several years ago from one of our local 'budget' stores for the grand sum of £1.....

Works perfectly, and is by far the easiest way of doing what you want. (Most of these nowadays consist of a rectangular body, with the SD card sticking out of the side. Mine is a somewhat older, neater design, where the SD card plugs into the end of the adapter's body, then has a cover that goes over it to "enclose" it. Can't seem to find one like this anymore...)

Failing that, you could perhaps try PLOP, although I think this is more for USB than anything else.

What is the computer make and model?

How exactly did you do an install of Puppy Linux to the sd card?

WHAT PUPPY VERSION?

If the install on the sd card is not correctly done.
Nothing is going to boot it.

I would intuit the boot media limitation is itself limited to media available in BIOS.

In other words, any bootable media should be able to refer to recognized devices even if SD in this case is not a boot medium in BIOS.

Then if not the case the question is the basic reason why.

@bigpup

Long-time memory serves you are booting SD on a much newer computer (this one is a little over 10 years old).

I wanted to experiment pfix=nocopy and getting browser config and repository databases out of /root on a SD card for maximum ram, but reality is sinking in (a newer 64 notebook w/>= 4GB ram to waste).
