Hello,
I am tuning my extlinux.conf for starting another OS.
This is a SD card:
- boot partition ext2
- second partition FAT32
So, how to setup that textlinux.conf for making booting the kolibri.img with INITRD? (see below).
I dont know how to make INITRD searching on another partition, different from the boot partition. The reason why I want that kolibri.img on that FAT32 is: kolibrios.org can write new kolibri.img on FAT32 partitions (and save the setups), where it can only read ext2 partitions (= cannot write kolibri.img on it =setups cannot be saved).
Any help is welcome.
THIS IS NOT a tinycore specific topic, only extlinux specific.
Code: [Select]
#
LABEL core4 fonic/lan/xorg/de stellite peter
MENU LABEL core4 fonic/lan/xorg/de stellite peter
KERNEL /boot/core4/vmlinuz
APPEND quiet showapps pause nozswap kmap=qwertz/de waitusb=5:UUID="cc9e97b9-67de-4e85-8f80-750a7d0f8841" tce=UUID="cc9e97b9-67de-4e85-8f80-750a7d0f8841"/tce4 lst=setxorg.lst mydata=setdata
initrd /boot/core4/core.gz
#
LABEL kolibrios
MENU LABEL kolibrios
kernel /boot/diverse/memdisk
initrd /?wheretogo?/kolibri.img
TEXT HELP
kolibri is on sdb2 (sdb1 is the boot partition)

You should be asking the kolibrios folks.

Hi floppy
Please make use of code tags when posting the contents of files. It's the button with the # sign on it.

Are you sure that all plays any role when specifying memdisk as kernel?

sorry, I dont understand.

With grub, it works. I have to put in menu.lst something like (from memory, probably not the correct syntax)
# distro on first partition
(hd 0,0)
kernel ..
initrd ..
# distro on second partition
(hd 0,1)
kernel ..
initrd ..
And I was searching such a method in extlinux.
The new though I have now, is a workaround: start grub from extlinux for using that parameter setting I have already working in grub.

That the filesystem from which an image is loaded with memdisk might not be of any relevance for the OS (though for the bootloader it might).

ok I can see why your kolibrios partition is fat32
Quote
What File Systems are supported?
Read/Write: FAT16, FAT32, FAT12 (floppy only)

but honestly, sorry for casting opinion but fat32 is dinosaur technology

since you know grub legacy works, why can't you make grub legacy your boot loader for TC and and kolibrios?
you could use all of your append line to append to the kernel grub legacy line

I guess you may like to add lang=de?

So, I use the quickest way = I putted the kolibrios.img on the ext2 boot partition (same as per memdisk) and I start it with initrd.
The workaround is:
- I save a kolibri.img (with new setups) on a FAT32 partition (it cannot be saved on ext2 or ext4)
- I copy that kolibri.img from the FAT32 on the ext2 back (now with my DE keyboard setup)
I personally recommend a try with that OS:
- tetris
- snake
-.. old fashioned games which are soooo nice. A very good thing I will show around me.
It is now on my SD card for use in train and spare time.
