Linux Laptop w/ 3.5" Disk, USB, and No Hard Drive? 396

ryewell asks: "I have an IBM Thinkpad 390 Laptop, PII 266Mhz, 128 MB RAM, with USB 1.0 port and a 3.5 floppy drive being the most important stats I would assume for this question. So my hard drive died, and I've been using a DOS boot disk and a program called Mel to do my word processing.Would it be possible to boot the laptop in Linux using a 3.5 disk, then using drivers access the USB memory stick that had an adequate Linux system on it?" With USB thumb drives getting to be as large as 512 megs, memory sticks weighing in at 1 gig, and Compact Flash cards getting into the 2 gig range, this might not be such a bad idea. There's the Linux Mobile System that looks to implement something like this, but are there other distributions or similar projects that might be of interest? If you were going to put together a custom system for something like this, how would you do it?
"If Linux can be configured this way, I would need no hard drive, and the created docs/info could be saved on the USB drive memory stick. This way, no hard drive means no moving parts, which means better battery life, and I won't have to buy a hard drive which at the best deal I can find is about $130 US after taxes, shipping, etc. And how cool would it be to run a laptop off of a memory stick! Unfortunately, I know nothing about Linux, but this might be a cool problem to solve for those smart and knowledgeable enough to figure it out. Thanks for any help you can provide!"

      Look into a flash file system [axis.com] to minimize writes to flash and to deal with inevitable bad blocks.
    • If you can get card services up with your boot floppy, and you should, it should not be hard to mount the CF as a disk there. Access time is faster than most CF devices and PC card adaptors do not require you to open the laptop.

      I'd just get another hard drive. If the system does not have a CD, do the install on another machine, move it and tweak it as required. Mepis [mepis.org] and other Knoppix based distributions should work without much or any modification. Moreover, they should work very well on that hardware

    • If you are going to use CF cards you have to make sure that you _DO NOT_ swap to it, CF, SD and company only have a finite number of writes to them. If it is an old laptop it will be swapping alot and your CF card will fry in a matter of weeks

      I know of disasterous results where people have decided to swap to a memory card

    • Well...

      Since CF Cards are pin compatible with IDE hard drives, and CF cards are currently the most durable (and cheapest) flash memory (even below USB Memory) I would put a CF card in the hard drive slot of the laptop...

      The only problem is that flash memory is no good at writing (very slow) and so turn off swap and try to minimize writes to the disk (ie, don't run too many cron's etc..)

    As other people are constantly pointing out whenever somebody posts an idea like this, "non-volatile" memory like MemorySticks and CompactFlash has a limited lifespan. It wears out after a certain number of erase/write cycles. That actual number is probably in the hundreds of thousands, but if you've got a Linux swap partition on there you'll be pounding the silicon pretty hard. Add to that a floppy disc as your boot partition, and ... well ... this sounds like one of the more head-scratchingly silly ideas I've heard in a while.

      Correct, and that is the main limitation of such devices. Just off the top of my head here, I can come up with an idea that just might work, but the OP had better be damn well prepared to use a very lightweight distro.

      Step 1: Partition that USB drive. You're going to need a very small / partition, and a much larger /usr partition. These are not to be messed with. You'll also need a /home-flash partition large enough for your personal use, and of course, a backup plan for when that drive fails.
      Step 2: Build your kernel. This can be tricky. Building a kernel that accesses the USB drive can't be that difficult, but you'll also need initrd support. Why? Well, because you've got 128 MB of RAM, and you certainly don't want to write to that flash drive all the time. Make a small, perhaps 32 MB initrd and mount it at /var. You can modify your init scripts to populate this directory safely. Symlink /tmp to /var/tmp, and now you've cut down a lot of your writes to your flash device.
      Step 3: Make yourself another 32MB initrd and mount it a /home. Again, your init scripts can safely populate this with all your dot-files. Anything you definately want to save must be manually copied to the /home-flash partition. Optionally you can take a look at the scripts included with Slax [slax.org]. One script (IIRC configsave) will make a tar.gz of all those pertinant files and save them to a partition on a USB flash drive.

      It should be noted that I don't know if the linux kernel can make and support multiple RAM drives at once. If not, just make one RAM drive, mount it a /var, and make /home a symlink to /var/home.

    It's a piece of cake. I've got a board at work running Linux (not uClinux, real linux) with the entire file system in flash. It has no moving parts and works great. Just build a kernel with support for the USB drive. In your fstab mount this drive as /. Follow the linux from scratch instructions to build the smallest system possible. You'll probably want to use busybox to the maximum.

    Also when building the kernel try to minimize the number of modules you build. Build things into the bzimage if you have the option. But at the same time only include the bare minimum things necessary.

    Lastly when you are building things with gcc be sure to use Os to optimize for size.

    Since its an x86 system if the USB drive is supported by the kernel this shouldn't be difficult at all.

    A couple of things to keep in mind with Memory Cards:

    1. Memory Cards usually have a "number of write times" which is sometimes around 100,000 writes. This is much more than enough when you're using the card for saving photos, and a card could probably last you a lifetime for this purpose. However, when you put an operating system with a swap filesystem on it, which reads/writes tons of times constantly, 100,000 becomes very restrictive and you could easily damage the card in a month or so depending on ussage. NOTE however that not all cards are created equal, so do some research on this. Try searching for MTBF (mean time between failures) along with the type of card you're planning on using on google.

    2. Although it is true many flash cards are slow compared to hard drives, some can be as fast or faster (depending on your system). For example, the SanDisk Ultra II CF cards have a *minimum* sustained write speed of 9 MB/s (that's MegaBytes per second, or aprox. 72 Megabits per second) which is VERY fast (however I do not know its MTBF specs). You can get such a 1GB card for about US$220. However, nowdays it is still MUCH cheaper to buy a hard drive.

    There are linux distros that will boot and run from CD-rom, but of course they access the noisy cd-rom all the time.

    There are network based distros but they go so overboard, they want to get everything from the LAN, which is not so fast and slow to boot up.

    In fact, in many cases the hard drive in the laptop is still there, it's just not perfectly silent.

    I would like a distro which booted from hard drive (or CD-rom, or floppy) and after loading what it wanted, and mounting network filesystems, shut down the noisy boot device for good, or at least until some unusual activity called for it.

    I don't know why noone has said this yet, but why not stick a copy of Knoppix in one partition on a large USB keychain device and boot it using a floppy with a boot manager on it? Then use the other partition on the keychain device for data storage.

    Booting Knoppix will eliminate the need for massive amounts of read/write, and you'd still have a bit of space to store whatever it is you are working on.

    Is anyone building one of these things as a Proof of Concept? I understand that memory uses more battery juice than the HDD itself.

    I think my ideas below and my question above come from my curiosity of how long the portable/hand-held DVD players last. I also wonder how long MP3 device batteries last. Days? Aside from the LCD and CPU chewing up maybe 60% of the battery life, at LEAST the storage and boot and system file devices could be on CF/Smart Media. Maybe someone might want to take the LSB to a new level: Optimizing the installation and locating of system files based on the type of medium to which the OS and user files are being written during install. And, suspend-to-disk, ACPI, and APM problems could be made to go away to a good extent, probably because the disk spinning is eliminated. i am not sure about communicating devices (modems and NICs), tho.

    Imagine this:

    -- Multi-slot CF/Smart-Media bay
    -- O/S Memory sticks/ in each CF/SM bay
    -- Energy-efficient/Solar or ambient-light-powered LCD
    -- Ability to swap O/S on the fly
    -- IR or compatible/comparable input device with own power supply (like the battery-powered Logitech mice...)

    Can't laptops go Solid State now? I imagine much of the laptop industry is sustained by momentum to keep cranking out mechanical disks. If an efficient CF/SM platter or storage surface can be optically read by something that is not having to spin at some 7,000 or 10,000 RPM, a lot of other savings might be made.

    Also, it seems laptop boards have fewer and fewer soldered components. Further reductions should lead to greater opportunity to bring solid-state laptops to consumer hands. If the OS could be on one the disk, and be swappable, the data on another swappable, disk, then when will a light switch on to make solid-state laptops that hold VMWare or Win4Lin in a Linux environment? VMWare and NeTraverse could then reduce their costs of product just by jumping to distribution/deployment of millions vice 10s of thousands. This would probably devastate ms' foothold, especially of XUL or XML or other code and W3C standards were followed better.

    I've netbooted an iPaq IA1 using a similar setup, CF to load the kernel (replace with floppy in this scenario) and a USB nic to netboot over. Just using a USB HD also works. As long as you can compile support for the device into the kernel, you should be able to use it as a root file system. Load the kernel, and it'll handle the rest.

    I have an ancient laptop with a broken keyboard. The HD/FD are both fine, as are the PCMCIA slots. No CDROM.

    What I would like to do is boot a single-diskette that contains enough code to fire up the PCMCIA networking, and either ENBD [uc3m.es] or something like it.

    That way, I could mount the HD in the laptop as a remote block device, and copy an OS across.

    Any ideas?

    See, I've got this old Chevy Nova. It runs fine and everything, but it's out of gas. Does anyone know of a way I could hook it up to my wood-burning stove?

    This way I would save on gas money. Have you seen how much gas is?

    I'm just wondering if this laptop is used in a portable, carry around with me manner, or if it's one of those laptops that says plugged into AC 99% of the time doing word processing.

    If it's the latter, do you have a network and at least one other machine? If so, how about a TFTP and network boot? I'm not sure if you have a boot rom in your laptop but it's possible or maybe you could find a cheap network card for it with one. Once the laptop's booted up it should be fine as long as it stays attatched to whatever network FS it needs to read files off of.

    I assume your bios does not allow boot from usb, so that's kinda out... Again, if it's a "static" laptop, one option might be a 44->40 pin IDE adapter, run the wire out of the case, and hook it to a standard 3.5" HD and use an old AT powersupply to keep it spinning. I'm just trying to think up ways to fix this thing with the typical "junk" around the average geek's house. I know there's usually half a ton of old cables, drives, cpus, cards etc in mine. If you're working on the premise that $130 is too much to spend I'd suspect that digging for junk or getting it from a friend may be an option in your case.

    I hope you recheck this posts to get this, because wow what a shit response you got from slashdotters! I have been trying to do the same thing for the last week or so and have found some good resources. Wierd that all the slashdotters say is "get hard drive". Yeah, thanks for that one!

    One of the best resources I've found so far is over at damnsmalllinux.org (in the forum, here [damnsmalllinux.org] they have a pretty good how-to on this. I also found a really good discussion of it in the Gentoo forums somewhere, but I forgot to sync my firefox bookmarks today, so I don't have it.

    For the project Im working on I can't use a hard drive, but Ive got heaps of memory - so Im just going to use ramdisk for swap space and stuff. That gets around the trashing your key thing. Probably not an option for an old lappy though! Good luck!

    from the i-r-teh-cheapest-mutha-fucka-evah dept.

    The power cord on my laptop just went fashizzle and I was wondering if anyone here could give me some advice how to run MacOS X on the digital clock on my Google shwag pen. I am hoping to spend no more than $.10 on parts for this. Oh, and I'd like to boot it remotely from my wireless MP3 server. Thanks in advance!

    If you value your time at anything more than about $0.50/hr, you'll find that the least expensive route is to buy a new harddrive.

    You're going to have cost for materials anyway, maybe not quite as much, but still a substantial cost.

    Lots have commented on the slow write performance of the memory stick. An even more pertinent issue is that all I/O through USB 1.0 (presumably this is USB 1.1) will be slow.

    Like others, I think a key question is whether there is an operational CD drive. If so, it would seem sensible to boot Knoppix from that and only use a memory stick for backup purposes.

    DSL has been doing this since at least 0.6.x. See: DSL USB + Floppy ~ 50 Mg [damnsmalllinux.org] and change the /dev/hda3 entries to /dev/sdaX, whatever your USB block device is recognized as. From damnsmalllinux.org, see the save settings to HD, and again use the USB instead. Rather amazing what they include on just 50 megs, and all apps are light weight enough you may actually get some work done.

    This is just the sort of thing RUNT Linux is great for. I don't think you can boot directly from USB, so you can boot the RUNT floppy, and it will run Linux off of the USB drive. RUNT is based on the umsdos filesystem, which is great if you want to use the pen drive for other tasks, but if you want to use it just for linux, you can reformat it with ext3 and copy all the files in. RUNT doesn't come with any graphical environments, but you can easily install the appropriate slackware packages to make it complete to your liking. Check it out!

    How abou you just give me a mailing address and I send you one of the two old HDD's I have collecting dust beside me?

    I have a Seagate 1.4gig and A Fujitsu 1.6gig. Both work. Hell I'll send both in case one fails in a year.

    Sorry it doesn't solve your battery problem but at least you won't have to be screwing around with boot floppies and killing flash drives.

    Geeze, for 130 bucks on Ebay you could probably buy and entire laptop which contains a 2-4gig HDD and just throw the rest away.

    Work smarter not harder.

    This may or may not be of help to you.

    In my spare time, for the past fifteen months, I've been writing my own low-level logic, which can be blown onto an EEPROM chip. The EEPROM chip is then soldered to a project board (Radio Shack P/N 26-117B) along with the necessary connectors and solid-state circuitry to allow you to use the spare (32k) memory in the popular "Speak N Spell" series of educational toys as a CompactFlash device!

    With the addition of a CompactFlash-to-USB adapter, one can use this setup just like a regular USB storage device! Think of the Linuxing you can do with that!
