Question Was looking for TinyCore forum but this isn't established here yet


First of all I've started this same thread somewhere else within the forum but haven't received a usable answer in some days, so I'm editing that thread here hoping this's a better place for it. The original thread is at:
http://www.linuxquestions.org/questi...f-size-838492/

Downloaded tinycore.gz file (which resides in my iPod) & was thinking of installing it in my 128 MB CFCard (which happens to hold now Lucid511). Although finally I managed to boot up this VAIO VGN AR250G notebook from the card (this notebook has no HD) it was functioning at a crawling pace which isn't acceptable. So now you know why I've tinycore: thought that the size of the OS had an impact on the speed with which it functions, probably too the place from which it's loaded (in this case, the said card), too.
Is it possible to install tinycore in the card without burning it first to a cd? Even more, can I have a live cd with more than one distro there &, of course, a menu at startup for making my selection of which distro to load?

If all puppy OS run from RAM I still don't understand why it (Lucid 511) was so slow in all its reactions (mouse pointer movement, keyboard characters input, etc.) & nobody answered my implicit question around this to this date (in still another place here). Any hint as to where to look for some info will be very much appreciated.

PS. How safe is for the info already in my iPod (photos, music & other files) if I try GParted to change (if possible) the boot flag within the iPod in order to make it a bootable device? Does someone here has tried this before?

Thanks in advanced!

Well, Let's give this a go.
You haven't given us much. I am going to take it you have eliminated issues around why your notebook is so slow. Lack of Ram? Access speeds? Lack of swap space? Usb 2 properly driven should give you 12 Megs/S which is slow, but not disastrous unless you're running kde.
If you haven't got swap space make some
dd if=/dev/zero of=/tmp/some_file bs=1M count=20
mkswap /tmp/some_file
swapon /tmp/some_file

Last few steps need root or sudo.

Let's pretend you have enough ram. I would start by building a kernel, with everything your viao needs compiled into it, and absolutely nothing else. Build this on another box! Make sure the cable from your phone is good, or you're down to 1MB/S and usb 1.0 which is crap.
If you have battery life in abundance, you might be able to suspend to ram most of the time, and leave it booted up.
As a computing option, btw, I think it's crap. Get some hd/usb disk for your viao, or else use the brains in your poser phone, which you'll probably get more out of if you can read it. I've been driven onto my Android pda in College and I find size a pita, but otherwise it functions.
Beware that with tiny distros (DSL, Tomsrtbt, tinycore) you're compiling against uclibc. If you need a uclibc based system to compile with, kevux does that in a live cd.

Question

Thanks for responding business_kid! I'm sorry I left out much of the useful data for receiving help with this but I had in the back of my mind that in the thread I was receiving help with the issue of installing Lucid within the CFCard I had all the relevant points covered. I overlooked that this's another/different thread within another forum-space that was about to be seen by different people, sorry!

First of all, this notebook has 512MB of RAM. When you say "access speed" I get confused, are you referring to access to the internet or to the card itself? In relation to the card I must say it came with a usb adapter & I found it in a Motorola cell phone box. It's a 128MB (as advertised, but it always show that in reality its useful capacity is around 114MB). I tried the Lucid installation connecting the card in 2 different ways: with the adapter in a usb port & inserting the card itself in its intended slot. The final working installation was made when the card was inserted in the appropriate slot.

Now, I'm just about to tell you some assumptions I've made. When I startup the system with the live cd I've the same RAM as when I start it with the card. The card is inserted in its slot & I assume it's as fast or even faster (its access speed) than a usb connection. The startup process is, probably, slower than with the cd but I'm referring strictly to the performance of the programs running after Lucid is running, properly. Here I'm comparing its performance with DSL running from a 64MB mp3 player (reformatted to be used as a regular pendrive a few years ago) in another defunct laptop (older than the one in this issue) which had just 128MB of RAM & a slower cpu.

In relation to the "Swap space" thing I've my doubts, too. Do you mean to reserve some ram for that purpose manually? Within the card itself? If the answer is the latter one then I must say that at the installation of Lucid I partitioned all the space available as a single one to be used whole for Lucid; I'm not sure if I can change that now without having to install it anew...

With respect to the usb point I'll just say that the card runs from its slot & not with the usb adapter. I must say with respect to the kde clause you use that I think I'm not using it.

With respect to making some swap space I must say that this notebook has no internal HD (the main reason for thinking of putting a 'resident os' in the card in the first place).

The commands you suggest in your post remind me that yesterday I finished reading a document in relation to the linux shell. This's an area that I need to practice to get acquainted with (this means that I'm lacking in knowledge of the shell/terminal). By the way, I'm running xorg as my wm, not xvesa.

In relation to building my own kernel (as of this moment you might have grasped the idea that I'm more a newbie than something else) I've no idea of how to even start that with. Don't get what's behind the clause "make sure my phone cable is in good conditions". I've an even fainter idea of what/how to do that thing of "suspend to ram", at this point I must say I'm completely lost: don't understand the purpose nor the mechanics.

In your last paragraph you use the letters "btw" which I can't comprehend. Also, what's that of "poser phone"? In relation to my issue of installing Tinycore in the said card in substitution of Lucid I must say that now that I've downloaded it I'll keep it until I find out how/where to put it (just for the sake of looking at it & seeing it in action) but, Ive the intention of keeping Lucid there & try to make all the necessary configuration changes that permit it to run as I think it should. Just one thing at a time! Thanks a lot!

PS. How frequently does the os needs to access the card (shouldn't it be running out of the ram, solely)?

Thanks for the detail in the reply. Sorry I was unclear.

The access speeds I was referring to are usb access speeds. A favourite problem is to connect 2 usb-2.0 devices and wonder why they are so slow; the cable only lets them do usb-1.0. If you're running from sdcard, fine.

As for swap, you need to reserve some 'disk' space for swap.

The problem is that a distro has to make a kernel capable of everything, which is big.You download a kernel source, and only add the bits you want. It's one way of making a leaner meaner machine, but leave it for the moment.

Suspend to ram is a way of switching off. Everything is stored in ram, instead of being powered down, and the box goes asleep. then you can wake up without a long boot process. Get going first.
BTW = By The Way - there's a lot of these acronyms in use. That's a common one
poser phone - I was being facetious. Mobile Phone
The last question about hard disk access would normally get you a complicated paragraph, but I'll spare you. Frequently.

A point in specifics...

I remember having downloaded & extracting DamnSmallLinux in a folder (within Windows XP) many years ago; the said iso file(s) were then copied to a bootable, appropriately formatted pendrive. It still works in some systems that the BIOS permits usb-booting. I used the same method for installing (frugal) Puppy Linux 412, 421 & 431 in its hdd. [Have the disk but not the means for connecting/installing to this unit.]

All these without the need for 'burning' anything into a cd. The problem is that the computer where this was done is dead & I've forgotten the application I used.

Do you or someone else knows of an application that can do the same in linux (Lucid511). It might depend on the form of the downloaded file: I downloaded & saved Tinycore.gz file. Was I better off with another form of the file?

Thanks for any help that you might provide!

run 'file tinycore.gz' and see what it is. the gz means it's gzipped. Probably a gzipped iso file. iso9660 is usually a recognised format. you can mount one with -o loop (best to modprobe loop first). Do exactly what DSL tell you to do with it.

Thanks for responding business_kid! I'm pasting the output of that command below:
"# file tinycore.gz: gzip compressed data, was "tinycore.cpio", from Unix, last modified: Tue Oct 12 22:14:17 2010, max compression"
In relation to that format (iso9660) you mention don't have an idea what it refers to. In relation to the other commands I'll fetch some info maybe by way of google. The last sentence of yours make me think that you beleive I'm using DSL for all this. If this's the case I'm sorry that I might have misled you to think that.
DSL is sitting down comfortably in a pendrive that used to be an mp3 player. I'm running Lucid511 from a live cd since this computer doesn't have a hdd (the last point I mention here is the reason I was confused at your point on 'swap files' before).
PS. Lucid comes with a file decompressor that's located on the desktop that says only "zip" & I don't know its name. It can't decompress the Tinycore.gz file. BTW, tinycore.gz is saved inside my iPod Nano, which isn't a phone, just a little more than an mp3 player & a headache!

Ok. Try this
unzip tinycore.gz
that leaves you with a cpio archive. make some directory, cd into it, and run
cpio -i ../tinycore.cpio
ISO9660 is used primarily with cdroms. CPIO is an old style Unix archive, commonly used in initrds. I always find the options messy - man cpio top be sure.
.zip files are handled by zip/unzip, .gz is handled by gzip/gunzip, .bz2 by bzip2/bunzip2. Those are some of the many archiove formats available on a normal linux box. I think even tomsrtbt (single floppy linux distro) has them all).

I'm sorry I left this discussion for so long but it was getting as long as my headache with this issue, probably it was & still is out of my reach (beyond my capabilities to understand what's next).
I hope soon I'm going to have accumulated enough mental strength to make another attempt.
I've read the whole thread again today &, if you explain a little what the command lines in your last post are supposed to do I'll jump into it sooner. I was thinking of rearranging the files I've accumulated in the CFCard within a folder & leaving the rest of it as free root, where I'd put the tiny thing. Not sure yet, though.
Happy New Year for you & your family!
