Booting slitaz-rolling with Memdisk

I'm trying to boot current Slitaz-rolling.iso from USB stick from an approach different from guide: memdisk.

I'm basing on these docs:

https://wiki.archlinux.org/index.php/Multiboot_USB_drive#Using_Syslinux_and_memdisk

https://mbusb.aguslr.com/howto.html

So I basically got ready a USB stick, installed grub2 on it, downloaded syslinux-6.03.tar.gz from kernel.org, extracted only the memdisk binary and copied it to USB.

Created menu entry for slitaz like this:

[CODE]

menuentry "slitaz-rolling" {

  iso_path="/path/to/slitaz-rolling.iso"

  bootoptions="iso raw"

  linux16 /path/to/memdisk $bootoptions

  initrd16 $iso_path

}

[/CODE]

Result:

Slitaz initial language menu does boot, but after selecting any language and hitting return one of 2 things happens: either next screen with just the kernel parameters but no "boot:" prompt, in fact, gets freezed here; or next screen doesn't enter at all and whole system reboots, as if a strange error...

How can I make memdisk work with Slitaz, if even possible?

Re: Booting slitaz-rolling with Memdisk

Hi,

Bootloader used in SliTaz is syslinux (aka isolinux, etc.). First, version is old (so I doubt, your new-version downloaded module can cope with it). Second, SliTaz (Pascal Bellard, to be precise) adds many patches to it since years, I think no one here have skills near to his to describe how this patched syslinux works.

As for me, sorry, I can't help you. Booting still like magic for me.

Re: Booting slitaz-rolling with Memdisk

I have never get memdisk working.

Can you try something like

[CODE]

menuentry "slitaz-rolling" {

loopback loop "/path/to/slitaz-rolling.iso"

chainloader ($loop)+1

}

[/CODE]

I use grub4dos (or grub4dos-linux) from linux iso.

[CODE]

title slitaz-rolling

    map --mem --heads=0 --sectors-per-track=0 /path/to/slitaz-rolling.iso (hd32)

    map --hook

    chainloader (hd32)

[/CODE]

Sorry for the late response.

Tried your code for memdisk, only got

"Error: no server specified. Press any key"

Then back to grub2 boot menu.
