Run Win98 From 16MB Flash Disk

    ... the folks at litepc.com offer small Win98 installations for flash cards, too.

    Cheers

  2. Disk-on-Chip by bobthemonkey13 · · Score: 4, Interesting

    M-Systems makes a device called the Disk-on-Chip that I believe can do this. Although it doesn't interface through IDE, it can be made to emulate a hard drive at the BIOS level, using M-Sys's TrueFFS BIOS. Therefore, operating systems (like Windows 98, I believe) that use BIOS calls to access the hard drive can use the Disk-on-Chip as if it were a hard drive. Other operating systems like Windows NT and Linux need the proper drivers / kernel modules to access the disk. The upshot of all of this is that I was able to get my own hacked-up minidistribution of GNU/Linux (which I naturally called Asshat Linux), to boot and run off of the 16-Megabyte Disk-on-Chip in a Visara 1783 thin client machine (formerly running QNX). I believe that the same could be done for Windows 98. If anyone wants info on how I did this, email me or post a reply.

    Skimming through the website, they appear to have a process to create an instant-on OS image that is custom-fitted to your application. As far as I can tell, it does something like this:

    1. Analyze your application to determine which system components it needs to run properly (which DLLs, device drivers, COM components, etc.).
    2. Create a Win98 install set up to only load the minimum necessary components.
    3. Snap a memory image of the Win98 machine with your program loaded.
    4. Compress this memory image onto a flash card.
    5. At runtime, expand the memory image back into RAM and pass control back to Win98 as if nothing had happened.


    There would probably have to be a few device drivers involved, but it sounds like a pretty cool idea to me. This way, you don't have to rewrite existing apps or retrain the dev team to make them work in an "embedded" environment.

    Coding those widgets in assembler is pretty time consuming.

    As for crashing, they'd probably have a custom GPF handler that forced a hard reset. You'd never see the BSOD and the longest downtime you'd have would be 6 seconds.

  5. wine+embedded linux by JohnFluxx · · Score: 4, Interesting

    What's the smallest you can get wine down to?

    It would be interesting to see if you can do this with embedded linux + wine.

    Advantages:
    * You can disable all the gui stuff (if it's embedded, then you might not need any gui)
    * You can hack it to make it smaller
    * You don't need a windows license

    Does anyone know how big wine is normally when compilied? libs and all.. I have no idea if it is a few MB, or 10's of MB's.

  6. Re:On the mac side by longbottle · · Score: 5, Informative

    You can install OS 9/X directly onto an iPod and boot up any mac that has FireWire with it. Very handy for full system backups and disk fixing.

    You don't install onto the iPod's buffer RAM, you install onto it's hard disk (5GB-30GB, depending on model).
    The filesystem of the hard disk inside is actually HFS+ (the extended mac filesystem) so this really isn't that difficult. The cool part though, is the firmware. Open Firmware (it's in all the "new world" macs) makes it possible to boot from any device that can hold system software, not just iPods.

  7. Re:Reliability? by Chelloveck · · Score: 4, Interesting

    Agilent and Tektronix (and probably others) have been using Win9x in their oscilloscopes and analyzers for years now. The truly "embedded" part is running on a separate CPU on a PCI card. Windows is simply used as a front-end to render the user interface.

    It seems like a win all the way around. These companies can focus on what they do best, which is high-speed data aquisition and analysis. They don't need to get into GUI design. They can use off-the-shelf parts for the chassis and peripherals. And end-users don't have to figure out some obscure UI like on the older equipment.

    Windows is reasonably solid, as long as you're not mucking around with DLLs by installing new software. Typically these devices ship with the app pre-installed, and nothing else is ever run.

    I still don't think I'd trust it for an unattended (eg, ATM) application, though.

    I give up on debugging. From now on, SIGSEGV is a feature.
