Hi Ceel, mojo
Based on your suggestions i tried several different things.
First off, I booted a working distro and created a 200MB swap space, althought I don't really get if I can count on that for "FRUGAL_RAM" values (I mean: does FRUGAL_RAM values mean the amount of ram + swap space or just ram?).
Anyway I created this swap partition, it can't hurt.
After that I followed Ceel instructions and installed mtools, after that the unetbootin.bin program was able to give me a bootable usb key, however when I proceeded with "Slitaz Live" using boot options "nomodeset screen=text" (and sometimes also noapic nolapic, 'cause whatever..) I get to an error:
VFS: Cannot open root device null or unknown-block(0,0)
Please append a correct "root=" boot option: here are the avaiable partitions:
..and proceeds to show me the two partitions on my laptop hard drive and the cd-rom. Then kernel panic and I have to manually power off.
I don't really get why it doesn't work with the "screen=text" parameter. What differences has it got from slitaz base?
@mojo
I've put slitaz-loram on the usb key and
"The default boot selects the best flavor according the RAM size."
well that's not true. i tried the base mode and it worked, but when I tried the "default mode" it showed up and error followed by kernel panic. The error was similar to the one above (VFS blahblah..)
I don't even know what is this thing in bios where I can dedicate from 2MB to 32MB of those 64MB to the video card. i don't know what that means in relation to X. How many MB of video memory does X need to go?
I think I am making confusion, it's just that there are too many variables in play.
Even if I yet didn't solve the issue, I want to say thank you for your support so far.
P.s. I don't remember what version of slitaz I installed some time ago.. I just remember this slitaz that would bring me to a graphical login and then give me a terminal window without a desktop environment, but was able to open other windows like leafpad.
P.p.s. I also tried unetbootin downloaded from the ubuntu packages. It had a slightly more eye-candy look but it didn't work. And also, the unetbootin.bin in order to work for me has to be executed with sudo. kdesudo doesn't show the files when I go look for the iso. But I guess that's a separate issue.
