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

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!"

I would not use MemoryStick

I would use a CF card and ATA adapter.

I would also keep in mind that write times for CF devices can be ...g...l...a...c...i...a...l compared to disk.

I LOVE GOOGLE.

Small Linux

[homeobocks]

Small Linux should have everything you need, on two floppies, to mount a USB filesystem. If not, it is simply the matter of compiling a kernel and sticking it on one of the floppies. Good luck with your project!

Puppy Linux allows you to boot off of a usb card

PUPPY Linux http://www.goosee.com/puppy/flash-puppy.htm
allows you to boot off a usb card and does not require a hard drive. Damn small linux and dynebolic are two other distros that work well with underpowered hardware and don't require harddrives but they both require cd drives.

Limited lifespan

[PCM2]

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.

I use a CF adapter in my notebook.

I have an older 400mhz Dell notebook. I am currently using a CF to IDE adapter in it.

It works great, i am using a 256 meg sandisk compact flash card and feather linux.

Overall the performance is not too bad. Battery life is MUCH better without the hard drive. Write speed is not too great, but since I usually ssh into my server and leech from there, i dont need to worry about that much... :)

it's possible

[Da_Slayer]

There have been many projects over the years to run Linux on just one floppy disc and within other very tight space/memory requirements.

Some examples of Linux distros that do this are:
http://sourceforge.net/projects/byld
http:/ /www.fdlinux.com/

But I really think you are looking for this:
http://linuxmobile.sourceforge.net/

Linux Mobile System (LMS) is a full Linux system whose support is the new USB Flash Memory Drives. The intention is to boot any PC with USB support with our system and therefore we will have every administration and analysis applications that we have selected, so we will not need install it. This way, always we will be able to get our Linux system ready to use in our pocket.

Now if you cannot boot the laptop with the USB connection I am sure you can use a mini/micro distrobution to boot the system with USB support and then have it read and run off the USB drive.

I hope this information is helpful in your quest. =P

Damn Small Linux...

DSL has been doing this since at least 0.6.x. See: DSL USB + Floppy ~ 50 Mg 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.
