Title: Kernel - Zimage
Post by: Seb on February 18, 2006, 05:26:46 pm
on other linuxes there is a "/boot" directory with vmlinuz or someting like that

where is my kernel in my directory/ file structure?

this question has probably a very simple answer..

and: is there a lilo/ grub "replacement" somewhere or how does my zaurus know it has to load the kernel when starting?

regards

your kernel is under a partition of your flash memory called "smf" (/dev/mtdblock1 if I remember well ... don't have my zaurus with me to check but you can see it during boot time)

as far as I know there's no lilo/grub replacement yet, but there's boot scripts to load init scripts from different partitions ... nothing for different kernels though

it *may* be possible to reflash dynamicaly the kernel at boot time (using dd for example) but it seems a bit risky to me and I don't want to fry my zaurus trying this one

hm..

mount /dev/mtdblock1 /mnt/tmp
gives
mount: you must specify the filesystem type

just to check i tried
mount /dev/mtdblock2 /mnt/tmp
this gives
..already mounted or /mnt/tmp busy

but:
umount /dev/mtdblock2
gives
..not mounted

so what is right? ALREADY mounted or MOT mounted?

and, after this, how can i "see" my kernel?

why do you want to "see" the kernel image?

If you need the file, it's in tools.tar for pdaxrom, zImage for other distros

The bootloader used by the zaurus is closed source.

There are solutions for true dual boot now,  see your post
