Additional 200k On Floppy. How To!

Announcements of packages that are now released.

Postby Uri » Sat Jul 05, 2008 4:22 am

Hi, All!

I have released good idea - how to free additional 200K on floppy.

In one word:
  • Download <a href='http://freesco.linux.kiev.ua/packages/utils/ramdisk' target='_blank'>RAMDISK (0.3.8)</a> and <a href='http://freesco.linux.kiev.ua/packages/utils/ldlinux.rar' target='_blank'>LDLINUX.SYS (as .rar archive)</a> and put it on your floppy (do you hear something about "backup" word?). Now you will have 200K free space for anything.</li>
Alternative download links you can find at end of post.

Known issues:
Please, be patient. This is a Alpha release, fully workable, but it has some limitations and not fully user friendly.
  • No indication of unpacking progress. However it needs approx 3*time for unpacking Gzippped ramdisk. Simply wait a minute after "Unpacking ..."</li>
  • Not available for hard drives (Do you really need additional 200K on HDD?)</li>
  • No error notification.</li>
In next releases i hope this will fixed. I'm waiting for your responses!

----------------------------

In steps:
  • Unpack with Gunzip original RAMDISK from Freesco floppy.</li>
  • Pack with <a href='http://www.7-zip.org/' target='_blank'>7-zip</a> gunzipped RAMDISK using this settings:
    • Archive format: 7z</li>
    • Compression level: Ultra</li>
    • Compression Method: LZMA</li>
    • Number of CPU Threads: 1</li>
    </li>
  • Using modified utility (7z-unp) - get from archive compressed RAMDISK (7z-unp .exe p RAMDISK.7z RAMDISK). Now you have LZMAed RAMDISK file.</li>
  • Replace GZIPed RAMDISK on floppy (970K) with this LZMAed RAMDISK(760K).</li>
  • Replace ldlinux.sys on floppy (5K) with modified ldlinux.sys with lzma ramdisk support (8K).</li>
  • Well, now you have free 200K on floppy.</li>
----------------------------

New ldlinux.sys you can find <a href='http://www.gigasize.com/get.php?d=pz9jlx625yb' target='_blank'>here</a> and <a href='http://www.megaupload.com/?d=LGLZN78Y' target='_blank'>here</a>.

Already packed RAMDISK from 0.3.8 <a href='http://www.gigasize.com/get.php?d=mf2vjxljlkf' target='_blank'>here</a> and <a href='http://www.megaupload.com/?d=LXCLPKVS' target='_blank'>here</a>.

7z-unp.exe <a href='http://www.gigasize.com/get.php?d=8vw2lvj4nhc' target='_blank'>here</a> and <a href='http://www.megaupload.com/?d=16J3LEFE' target='_blank'>here</a>.

This sounds very promising, I hope they keep developing it. The other drawback that I saw was that it says 66MB to decompress. So I am guessing that you need at least that much memory in your system as well ??
If you are afraid that you might make a mistake. The chances are high that you will never learn anything.

Looks like no one use freesco without hdd :)

I'm using two floppies and no hard drive for freesco. For last 2 months proposed scheme with increased free floppy space works fine.

I'm happy ;)
